reverse sounds you mean pdc? if so yes it works, but no constant beep when very close to an object. anoys me to no end. anyone found a solution to this?

as for climate control, what do you mean? mine doesnt show anything to do with climate control

---------- Post added at 06:29 AM ---------- Previous post was at 06:16 AM ----------

anyone managed to fix some of the simple bugs, like auto answer? programing steering wheel keys etc?
[Android Head-Units] sd_dracula:
I never went for one of these but in my searches a while ago I came across this harness which might help with keeping the factory reverse sound: https://www.ebay.co.uk/itm/CTRBM001...724764?hash=item3cf48a091c:g:ubUAAOSwJ3RaviAA

Would be nice to know if it actually works :)

I've been slightly out of this for a bit. How is everyone getting on with their units? Mine is still going strong. Snappy, brilliant to use and impresses everyone who gets in my car.

I also have the corresponding Audi model in an A4.
[Android Head-Units] skezza:
Obviously you'll never know until you try, however my first impression is..... No.

The reversing sensors do work with this unit. They just don't work as OEM because the CANBUS module isn't replicating the same functionality as OEM When you install a generic aftermarket radio, you basically cut all CANBUS communication. It becomes a dumb radio (POWER, POWER_ACC, GROUND, FLEFT_SPEAKER, FRIGHT_SPEAKER, RLEFT_SPEAKER, RRIGHT_SPEAKER... and so on). You've cut all data communication. This is why our radio doesn't work without the CANBUS module, it is essentially translating the CANBUS to the radio and to the vehicle. A dumb radio works with a power line and accessory line. Our radio actually does have CANBUS, hence PDC, steering controls, blah blah blah.

By all means, give it a punt, but my educated guess would be.... no.
[Android Head-Units] Carlosjpt84:
hi, never had the battery draining issue but might help other people out. btw(e bom ver mais um portugues por aqui)lol do your sensores work correctly? continuos beep when you have to stop?
[Android Head-Units] djkostt:
Hi yes my sensors do work correct and all beep fine , i have read somewhere that alot of people is having issues with the sensors , i also think all has to do with the CANBUS box provided by the supplier when the headunit was purchased and also the MOST network being broken ... The one provided to me was a

Bagoo (BMW-BG-O4)

For : BMW E90

HW : V1(49)

S W : V101

P/N :

S/N : 001205

If many still fighting with this headunit most of your faults is due to the MOST network of your vehicle being broken , your removed oem headunit acts a bord computer and once removed network will be broken and then most signal will be lost in the network and modules won't be able to communicate , relocating the headunit and connecting the fiber optic will fix the problem ... I recommend the boot of the car or beside on the glove compartment you will need to splice from the radio wire loom the

Green - Can High Pin#9

Orange - Can Low Pin#11

+12v (yellow permanent) To Pin#15

Ground (Brown) To Pin#12

Leave them long enough to reach the glove compartment , you also need to get a connector that will connect to the back of your oem headunit , if it has the (ground , +12v yellow permanent , Twisted green+orange(Can +/Can-) , Ground - brown) hanging from this connecter even better you will need to connect with the wires you just spliced , connect also the 2 fiber optic that is connected on the radio wire loom , this should fix the MOST network .

Ya eu estou sempre por aqui no silencio , nao posto muito a nao ser que seja um topico que precise mesmo , acho que o topico deste autoradio e muito interessante por causa dos diferente tipo de falhas que a dar ao users do xda e por ser um autoradio que instalei e no meu bmw e pensei ser plug and play e que nao iria ter de usar muito a cabeca mas ate foi bom diagnosticar o autoradio.
[Android Head-Units] Luka26:
Hey everyone. I think I have the pb7890bp system, but I'm not exactly sure. It certainly looks exactly like it, but its os isn't Android 8, it's Android 6. I guess I have the older model. I think I bought it before 2018 (I'm not entirely sure). It's 2/32, it's the same res, and has octacore mediatek @1,5ghz.

Anyways, the radio started lagging (the sound stutters) about 3-4 months ago. Sometimes it stutters every 5-10 seconds and it's really annoying. The radio itself doesn't lag. Only the audio does.

I want to update it. Maybe that would fix the problem. I can't find the firmware to update it. Could anyone help me?
[Android Head-Units] jerkeife:
The canbus powers the radio, but I don't know if the decoder has anything to do with that.

That is exactly what I am seeing. I am in the US and the return address they gave me is the US but who knows where a new one will ship from and how quickly it will arrive.

This is absolutely not a fix, but a work around. Share the article if you still have it. I have a background in vehicle controls but never worked on the CANBUS system. Perhaps it is even something I can code on the car itself.
[Android Head-Units] skezza:
If you do a quick turn off and on, with the 30 second thing, you should be fine, because it takes more than a few minutes. It takes somewhere in region of 2-5 minutes for the bug to manifest itself. I sat in the car, locked it, unlocked it, got in, got out, and never had an issue. It seems to be having left for a minute or two. Something changes, then you open the drivers door and bang, the unit powers up..... in a powering down state and then the canbus gets fragged and goes tits up.
[Android Head-Units] erronr:
Maybe if enough people complain to xtrons they will come up with a fix. Or they just have no idea how.
[Android Head-Units] skezza:
Is that correct? I was under the impression the ignition powered the radio, but the canbus provided the interface between the car ECU and the radio. Hence the radio operates erratically without the canbus decoder, but you can see it powering on?

The only good thing about a few of us seeing it, is that the guys at Xtrons can't easily ignore it. If it's a software bug, it needs fixing. If it's a hardware bug, it needs fixing. I would suspect it's a software bug, because they've been knocking out these units for years and the canbus, as far as I'm aware, has never been a major problem.

Do the US have a service depot for Xtrons? The UK, does but it's operated by an outside company. I guess they just post/receive items and not much else. Probably one guy in a building somewhere. I would drive round, but it's a solid 2-3 hours away so not worth it.

I'll have a look for the article. I spent hours yesterday searching for aftermarket radio canbus e90 and there were lots of discussions on it. Most of them were suggesting the canbus isn't compatible with aftermarket radios at all, but that's the whole point of this decoder right?

Like I said, it's a hack..... and it's a working hack and in the grand scheme of things, I would probably still keep this unit because other than this one issue, I'm really starting to fall in love with it. Why the **** can't they get such a trivial thing right though?
[Android Head-Units] skezza:
There will definitely be a solution to this problem. They just need to debug it. Perhaps the problem lies in what jerk said above, regarding coding of the car.

I need to buy the coding tool off eBay as i can't do it right now.

Edit: Hello, so there are certain door configurations you can code..... I wonder, I wonder.

I now NEED to buy a USB cable to code this car. Problem is, I'm used to VAG. This is a minefield for me.
[Android Head-Units] skezza:
I'm looking at codes now. Will update if I find anything.
[Android Head-Units] jerkeife:
I missed this. Good to see.

Hopefully.

Let me correct my phrasing. Full disclosure - I need to check wiring diagrams but this is what I assume to be correct. The radio should have a designated power circuit (through a power bus - think fuse box). However the radio has an enable mode to actually pull power from that circuit. Some sort of built-in switch that cuts the power (like an accessory-on circuit.) When the ignition is turned on the controller (ECU or whatever BMW uses) reads the ignition on and sends the signal to allow the radio (and anything else that should be on with the ignition on) to pull power. I don't think power is actually run over the canbus but the canbus is the logical place to control the state of the radio. This "accessory-on" circuit could be built into the radio itself or it could be outside the radio. I suspect that an outside module controls the state of the radio. This would mean we don't require on the aftermarket decoder to turn on the radio (tested and proven by erronr) . The decoder is only needed when the two modules need to communicate with each other. For instance I believe that the radio actually stores and shares the time with the message center on our instrument cluster. This means the radio sends out an encoded message that the instrument cluster needs to decode. So in the case of our car, the xtrons radio sends out a coded message for the time. Our decoder translates that from xtrons language into BMW language and passes it along to our message center. The message center reads and

I'm assuming the US is a similar situation.

Same as above.

Like I said, it's a hack..... and it's a working hack and in the grand scheme of things, I would probably still keep this unit because other than this one issue, I'm really starting to fall in love with it. Why the **** can't they get such a trivial thing right though?[/QUOTE]

The trivial things are often missed because they are secondary or tertiary considerations.
[Android Head-Units] skezza:
I'm returning the canbus on Monday but I am really not convinced it's a hardware issue. It's clearly a software bug and i'm not even convinced it's the car now, because earlier when i tested, the steering wheel was still able to communicate with the air conditioning unit.

Xtrons need to look at this and work out a fix asap.
[Android Head-Units] erronr:
I've noticed my old canbus has a different software version than the new one. But could be different manufacturer and make no difference. I haven't run into the canbus issues since swapping them out, but not extensive enough testing yet.
[Android Head-Units] skezza:
So are you running your old canbus box then? Is it working fine whereas the other canbus it isn't? If so, I think that answers the question really. It's clearly a buggy canbus box, not even the software. The big problem is, if their replacement doesn't fix it, then it's a hardware issue with that decoder and we need the same one as you, and I cannot see us getting hold of them easily. They're car specific after all and each manufacturer does it differently. I had a look on Erisin they have their own canbus, maybe they would sell me one. Be interesting to see how much they wanted.

I've fitted the unit more permanently today. I tried my best to make the climate control unit fit flush. Filed the tabs off, modified the bracket etc, but nah, I can't quite get it flush. I think if I keep going at the bracket I could get it nearly flush though, so I'm half tempted. It's only the bracket after all. Xtrons would probably sell me a new one for a few quid. I'll have another look in a few days. Had enough of it today.

The unit is good. I like the unit. Therefore, when I weigh it up, I would still keep this radio over sending it back. Yes, the sleep thing is annoying but we'll see if a new canbus decoder fixes it. I would still prefer to keep it though.
[Android Head-Units] skezza:
I've asked the guys at Erisin for a price on how much for one of their canbus decoders. There's a fair chance it'll be different to the Xtrons one so might work better. I've noticed something very strange today. When I pop the boot on my car, a little logo appears on the head unit to say the boot is opened. This doesn't happen for the front drivers/passenger or rear doors. Should it? It also doesn't read anything from the AC climate controls? Again, should it? This is all pointing to a bad canbus box to me.
[Android Head-Units] skezza:
OK, so today has been pretty much a **** sandwich as far as this is going.

Firstly, there is zero chance you'll get the climate control flush with the dash. Modifications to the bracket will shave a few mm, but today, I ditched the bracket altogether as a quick experiment and it still stuck out at the bottom. I think the fascia on the unit is slightly bigger than, say, the Dynavin unit, which fits perfectly and flush and everything lines up beautifully. Problem is, the Dynavin unit is **** in comparison imo, and is way way more expensive. I suppose you have to weigh up what's more important, style or substance. Right now, I'm going for substance. Some people get funny when they drive BMW's and Merc's, they like everything OEM and lining up beautifully. I like my equipment to work, hence I won't spend a grand retrofitting the iDrive system.

This unit utterly blows the Dynavin away and I'd go as far as saying it beats the current generation iDrive as well. With a few tweaks and apps, you've got probably the best piece of kit available in any car at this current moment. if you're willing to spend time configuring it to your needs, then the possibilities are almost endless. Mine, currently, calls people via Google Now (Mtcdialer), plays Spotify via Google now, is almost 100% handsfree etc and I've used widgets to make the home screen look unbelievable. It blows any iDrive system away imo. Even with this stupid canbus issue, the boot time is only about 25 seconds. Hardly enough to bother me, that said, I am returning the canbus box tomorrow....... which leads me onto my next problem.

Secondly, and more importantly, the ****ty part of the **** sandwich (The above was just the bread)...... NO, the unit does not work without canbus decoder. So once I return that decoder box tomorrow, I will be left with a £300+ paperweight in my car. I've tried disabling canbus in factory settings, but the car is clearly shutting it down and the reset pin simply causes the unit light up and nothing more. This is pretty much all bad. No radio for 3 or 4 days, or maybe longer while Xtrons piss about deciding what they're going to do. Let's hope they've got a quick turnaround. I'm thinking, next day, not next month!!! Luckily it's going to an English depot, not a Chinese one. My hope is they've got them boxed ready to send out immediately. Fingers crossed.

Finally, just to rub salt in my wounds, the adapter I ordered from Germany promising to integrate the diversity antenna on the E90 with the DAB dongle doesn't work. In fact, it causes the USB dongle to fritz and go funny, so there's obviously a short of some kind. I will be contacting them to ask how to proceed. I have another DAB adapter that is designed not for the E90, rather for a ****ty old Mazda and it's crappy unamplified antenna, but it worked incredibly well for over a year, so I'm going to give that a go despite all the instructions stating it won't work. It specifically states that it's designed or non-amplified antennas and the E90 has a specially designed diversity antenna with 2 separate amplifiers, so yeah, not holding my breath. Still, no harm in trying eh?
[Android Head-Units] erronr:
Correct. I out my old canbus in and I can't for the life of me duplicate the issue we have had. And opening the doors, Trunk show up on the screen as intended. On the canbus that came with the unit, at least for me, it would just show the car not the door opened. Also the head unit is displaying in f instead of c which I wouldn't find to change before, so I'm guessing that may have had something to do with it?

[Android Head-Units] skezza:
This is excellent research and pretty much clears up the debate. The canbus box is clearly not working correctly. Do you know who supplied that canbus box? Erisin? Xtrons? Eonon? I assume it came with your previous unit.

I am going to give Xtrons a chance to replace it and hopefully all will be well, but if the replacement is broken as well, I want them to acknowledge that it's a problem and they need to do something. Erisin got back to me this morning and have said they'll supply me one. The problem is, as we all know, most of these companies buy wholesale don't they, from the same suppliers. How do we know Erisin won't just send me the same box as Xtrons. :crying:

I might send your photo to Erisin and ask if they have the same canbus box as the one that works. See what they say.

We're making progress. Once this is sorted, we really have a top piece of kit.
[Android Head-Units] jerkeife:
I asked Xtrons what I was supposed to do without a radio until I got the new decoder and they said they would send me a new one to try and see if it helps. Perhaps ask for the new one first?
[Android Head-Units] skezza:
Too late :( I've already posted it lol. So that's happened; I'm now stuck with the most expensive paperweight in history fitted into my car. £300+ for a big black box currently. Let's hope Xtrons don't mess about. I've posted it 1st class tracked so I will know when it's arrived and I will send them the tracking number so they are aware that I know. I can't really fault them so far, they've said they'll pay for the return postage etc (not expecting miracles) so let's see how it goes. I'm happy to live without the radio for 3-5 days if they can get this right. What I'm not happy to do, is sit around for a month while they decide whether the box is faulty and needs repairing or just needs replacing.

We'll see.
[Android Head-Units] skezza:
[MENTION=4386175]jerkeife[/MENTION]

I'm also concerned because [MENTION=426596]erronr[/MENTION] has already been able to make his unit work with a different canbus box from either an old Xtrons or a different radio altogether. If there is a hardware design fault inside the canbus decoder, then no amount of replacements will fix that. The design/software needs fixing, but getting a company to admit their product is faulty isn't always easy. I'm waiting to hear back from Erisin. If Xtrons send another bad canbus, I will point them in the direction of this thread and show them that a member has it working with a different version. I will also wait to see how much Erisin quote me. If they say £15 shipped, then it might be worth the money.

Even this morning, this unit never ceases to amaze me. I can tell it to play a totally random album from Spotify and the microphone is so clear it picks it up. What's everyones biggest complaint about these units? Rubbish mic quality and rubbish Bluetooth quality. These two issues don't affect this unit. We potentially have an absolute gem here. I really hope it's not ruined by something as stupid as a ****ing canbus decoder, something which these manufacturers have been making for years.

Oh and btw, I hammered it last night. Had it playing Spotify via WiFi, and using maps. Temperature? 57 degrees. They've even got the freaking cooling right. Good audio, good bluetooth, good microphone, good screen, good processor, bug free ROM....... Come on Xtrons, you're on the verge of greatness here!! Don't let this trivial issue ruin it.

That is the seller I purchased my old unit from. I have sent them a message to get a quote on the canbus unit I have. I will keep you guys updated.
[Android Head-Units] skezza:
Very useful. You can't beat Aliexpress for stuff like this. They'll probably be cheaper than Erisin and they'll be able to source the matching part. If they can do us one for a reasonable price, I will happily pay and wait for a month instead of arguing with Xtrons.

Do the climate controls now work with yours too? Mine never interacted but I've seen videos of them showing changes to air con on the screen?
[Android Head-Units] erronr:
I didn't know there was climate control on the radio. Where is that located?
[Android Head-Units] skezza:
I mean the climate control in your car? I assume you have it. If you have manual AC then it wouldn't work because that's mechanical, but my car has the dual climate installation and on the video, when you press the AC on and off a little logo appears on the radio. It never did on mine. It didn't remotely bother me. It's a nothing feature, but it's something else pointing to a problem with the decoder.
[Android Head-Units] erronr:
Mine does not do that at all.
[Android Head-Units] skezza:
Not a big deal. Not a feature I'm greatly arsed about.

What I want preferably is not to lose the canbus integration when the unit returns from sleep. That's what Xtrons need to fix in this new canbus box they're sending me. Like I said, I hope they're ready and waiting. I would like it by Thursday or Friday latest.
[Android Head-Units] erronr:
Well, the place I bought the old radio from quoted me $45 on the canbus. :/
[Android Head-Units] skezza:
Wow 45 dollars? I assume that includes free shipping? That's still a lot. Erisin haven't got back to me yet, I'm still waiting.

Let's hope Xtrons are going to come good here. I will post them a link to your replies about the old canbus box working, if their new one doesn't. They've got an opportunity to show their customer service is better than the rest here.
[Android Head-Units] jerkeife:
So I finally found a fuse that I am confident in using for the 12v constant. It is one of the central locking fuses but the opposite of what I used before. Fuse 56 seems to have saved the radio presents but the clock will not save. I am guessing that is because I am currently turning the radio off every time the vehicle shuts off to "reset" the decoder. It also doesn't seem to cause the radio the turn on at random points.
[Android Head-Units] skezza:
Which did you use before 56 or 57?

I still haven't wired mine in. No point currently, but I was hoping to use one of the standard sized fuses as I have the correct size fuse tap. Otherwise i need to order a new fuse tap, grrr.

Don't forget your clock might be lost if you have it auto update from GPS.
[Android Head-Units] jerkeife:
I was previously tapped into 57. This gave me errors with losing radio presets, clock, intermittent radio powering on, etc. I am now tapped into 56 and the only issue I have is the clock not staying correct. Auto update via GPS is off.

Got this today after they said they would ship me a new CANBUS before I sent mine back:

Hi,

We have already ordered the canbus from the factory, hopefully, we can send it to you next week

Please do not hesitate to contact us should you have any further questions.

Kind regards,

Abby
[Android Head-Units] skezza:
I'm also dealing with Abby. She has said "we'll get it out to you this week". I'm going to ask if they can get it posted out to me tomorrow because I'm now driving to work in bloody silence. There's only so much engine noise you can listen to before it gets tedious!!
[Android Head-Units] erronr:
If you set it to get time via gps that should work? Mine seems to be getting the itme via canbus.

Thanks for the fuse info ive been slowly working through several fuses.
[Android Head-Units] skezza:
Like I said, I'd prefer a full size fuse rather than micro, otherwise I'd have to buy a new fuse tap grr.
[Android Head-Units] skezza:
They're posting a canbus out to me today. Hopefully get it tomorrow or Friday :)
[Android Head-Units] jerkeife:
I found many posts that say various fuses work. This is the only one that's worked for me so far. I have tried with get time via GPS on and off with no difference in outcome.

Great news! Let me know if it fixes your problem.
[Android Head-Units] skezza:
Credit where credit is due, they shipped it today. Sent me a tracking number, via DPD who are a pretty good delivery company. I expect it'll arrive tomorrow or Friday ;)

Will let you know.
