I'm happy to file down the tabs, but yeah, like you said, the unit really needs to be working before I start making wholesale irreversible changes. At least a new climate control unit is only £49 off eBay. Could be worse.

They've sent me an RMA too and offered to pay for postage; like you though, I'll end up potentially having no radio while they fiddle and piss around for a few days. I don't think the radio works properly (or even at all) without the canbus box either. If it works partially, I can live without it, but I really don't want to be driving around for a week while they fanny about sourcing a new canbus decoder for me. I'd need to look though which I'll do tonight or early tomorrow morning. I'll update once I know. If it does work, I will get it posted tomorrow so I can get a new one back next week. I wouldn't be surprised if it doesn't fix it though.

The other option is I could rip it out completely and put the OEM one in loose or partially re-fit it, but hardly ideal is it? I never had these problems with Erisin :D Mind you, that had no canbus at all :)

Did you watch the video I recorded? The fact, your description sounds exactly the same as mine, means I'm pretty sure our problems are the same. Are you a UK customer as well? Be interesting to see how quickly they operate.

The 30 second ACC fix should work, assuming your canbus hasn't bugged out already!! It's really really important to note that. Once you've bugged your CANBUS, it's done. Dead..... and it'll be dead for half an hour to an hour or so regardless of this setting. I'm not uber clued up on the car, but I found an article discussing BMW canbus and aftermarket radios and essentially, there's some kind of lockdown system. If any kind of discrepancy is detected, the canbus circuitry for the radio is shutdown. So with that in mind, I think the car detects the unit powering down, but the unit should be powering up as the door has just been opened. This then puts the car into a fail-safe and canbus into a shutdown mode. You could disconnect the battery for a quick answer, I suppose, but no point. Just wait an hour or so. Then you'll have working canbus everytime you enter the vehicle, assuming you have that 30 second mode activated.

This isn't a fix though is it? This is simply booting the radio from cold everytime you enter the car and that really shouldn't be necessary. It was one of the selling points of this particular piece of equipment.

I will try those settings tonight/tomorrow before sending it back. Has to be worth a try.
[Android Head-Units] erronr:
I have used the unit with the canbus disabled. The radio worked, that is all I tested. I was trying to figure out why my canbus stopped before reading this post.

As of now, I don't have the 30 second thing selected and since swapping my canbus to my old one ive kept canbus working. That being said, I havent done a quick turn off/turn on. I will try that shortly.
[Android Head-Units] Jamble1984:
No luck, i finally got the headunit to accept the firmware, only for error messages to appear, have now officially given up with it, Ive kind of got used to getting in the car and immediately toggling the network time on and off, apart from that, the unit is great.

Tasker is your friend.
[Android Head-Units] Elmore78:
Hi guys, been keeping tabs on these posts before buying so I can troubleshoot any issues when installing. Have taken the plunge and bought one, went to hook it up to my 2010 E91 but had real problems getting the wiring harness to fit. It seems to push up on the left hand side as I pull the securing lever across and will not clip shut. Then blew the fuse when I started up (obviously). Anyone else had this? All the wiring corresponds on both wiring harnesses, I have all 8 speaker cables.
[Android Head-Units] Legolas8911:
It was a very snug fit on my unit and the security lever did not quite latch on so I had to force it a bit but other than that it works perfectly
[Android Head-Units] Elmore78:
Thanks Legolas8911. I'll give it another go with a bit of brute force. Was a bit worried I'd snap something in the car. I've tried it a few times and every time I manage to force the latch even half way across it refuses to sit straight, popping out on the left side where the speaker cables connect. I've got a couple of blue plastic pins in the sides and bottom of the BMW harness - should I be removing these? I don't think they're helping with the fit but it seemed to be the same when I gave it a go with them taken out. Will perservere, and if no luck will see if Xtrons will mail me a new loom.
[Android Head-Units] skezza:
Those quad lock harnesses are evil.
[Android Head-Units] Elmore78:
They are absolute evil, Skezza! Utter cack. Abby from Xtrons tried to flog me a fibre optic adaptor to fix it?! But brute force won through in the end :)

Now I'm all up and running I seem to be having problems with Wifi Hotspot. Anyone else encountered any issues?

Can see the routers up the entire street so Wifi seems to be scanning properly, but my phone's hotspot whilst sat in the car WITH my phone? Nowt.

Android compatibility maybe? I seem to remember seeing something about it not being tested on versions about 7 so I'm a little concerned.

I'm using a Huawei P20 Pro Android 8.1.0.

Hope I can get this resolved - otherwise it's bluetooth audio and crappy radio for me for now...
[Android Head-Units] suhail_kapoor:
Latest update works fine. Resolved the usb error / permission message. Volume output seems more louder than before.

Mute is still a mess.

clock problem and change the appearance

Hi,

i was reading the 19 pages about these threat. I have the Xtrons PB7890BP and i have too the issue with the time, clock always freeze when you turn off the car.

You found it some fix for that?

And my second question is how can i change the theme or the app icons, i dont like they have a square around the app icon, i prefeer see only the app icon and not that square around them in every app.

sorry for my english, iam from southamerica :)

thanks in advance
[Android Head-Units] jagman96:
I'm having a problem with my car battery dying since installing the 9"head unit. I also cannot get the clock to work. I have the yellow wire hard wired to the positive terminal of the battery. I had to plug the two blue wires together to get the amp to work so I could hear sound. My battery is on a trickle charger overnight. Hopefully the battery isn't dead in the morning. Once the car starts I'm going to try the settings posted at the very beginning of the thread forcing the unit to power down after 30 seconds without acc power. Hopefully that fixes the power draw. Frustrated.

Also, I have not rooted this device. I would love for the mic button on the steering wheel to activate Google Now voice. I would also love to have the head unit ignore when I tap the change source button on the steering wheel. Lastly I would love to control hanging up the phone from the steering wheel. Any way to make these changes without root?
[Android Head-Units] Elmore78:
Issue now resolved - my bad. WiFi hotspot is set by default to 5ghz AP band in the advanced settings. Changed to 2.4ghz and I'm off and running.

Has anyone managed to figure out if there is a way to stop the music cutout when reversing? Is this something that could be done through Tasker? It's pretty much the only thing that's irritating me about this unit so far. I don't have a reverse cam fitted as of yet
[Android Head-Units] jagman96:
This
[Android Head-Units] skezza:
No idea why Abby was trying to flog you an adapter? The reason the quad lock thing is a pain is because it's really tight. The OEM BMW is only slightly better. The Xtrons Quad Lock is horrendous. It's so so tight. I have removed this radio a few times and honestly, the hardest part of the entire removal, is trying to disconnect that quad lock. Junk.

I spotted that you fixed it later on, but here's a tip, some phones also add devices to a 'Authorised list' (basically a dumb form of MAC filtering). I had this problem, my head unit refused to connect but once I disabled the 'Authorised list' it started working no issues.

When you say resolved the usb error / permission message? What was there to be resolved? I don't think I've seen an issue with permissions.

Volume seems louder? Really? Are they driving the amplifier harder? I'm half tempted now, but my unit has been modified with useful things I've added.... Can I be arsed to update it, if I'm unlikely to benefit? :rolleyes:

Why is mute a mess?

Tasker is how I fixed the clock issue.

However, I've been doing further research and the fix is probably to disable the clock sync in MTC Manager which will then stop it pushing to the ECU which sets it around the various clocks in the car.

You can install Nova Launcher or any other launcher if you want something more Android like. I really like the OEM UI :)

Regarding your battery drain. Not a clue, but I would put an ammeter on the car and start pulling fuses. If you've wired directly into the battery, is it fused?

The music shouldn't cut out. It should quieten slightly.
[Android Head-Units] Elmore78:
Yep I politely declined the fibre optic connector from Abby! The music used to fade down on reverse with the OEM (I have parking sensors) but now cuts off from whatever source I'm playing (Spotify/bluetooth audio). As soon as I go out of reverse the music comes back in, slightly quieter with the parking sensors over the top, as expected. Might try disabling the parking sensors and see if its related, the beeping is a little annoying anyway and there's no solid beep when close to objects, as others have commented. Will investigate further and see if I can shed any light on it.
[Android Head-Units] skezza:
I only see this issue with YouTube.... this is explained by YouTube's non-background audio though. When you go into reverse, the radar overlay technically puts the YT app into background mode. Disabling the overlay stops this from happening, but the overlay I find very useful.

As you said, no constant beep so you need the overlay and camera really. I have the camera. Worth the few quid I spent installing it. Honestly it is.
[Android Head-Units] Elmore78:
Thanks for the tip Skezza, I'm up for getting a camera but a little nervy about the wiring for the install. Someone mentioned the Xtrons ones come prewired to power from the HU? If so has anyone got a part number to steer me in the right direction, there are tons on the site?

Also, how do you turn off the overlay? Don't really want to switch off my sensors but would like to have a play around and see if it works with the cutoff.
[Android Head-Units] jagman96:
No fuse. I have an E92 M3 (not sure if that matters). If I were to tap into a fuse in the fuse box, which one would you tap into?

I jumped started the car last night and got it running so I changed the setting to shut down the head unit 30 seconds after turning the off the car (as explained on the 1st page of this thread). Will see if that helps.
[Android Head-Units] skezza:
The overlay i believe is called 'radar' in the settings. Just disable it :)

The wiring of the camera is so easy and by the sounds of it, I did the hard part. Apparently the camera can be powered from the head unit. I should have checked, but I didn't. I cut the insulation on the reversing lights and wired it in the good old fashioned way, with a relay and some wire. The whole thing took a few hours and went very smoothly. The camera is an aftermarket OEM replacement and is absolutely fine for the job :) :fingers-crossed:
[Android Head-Units] skezza:
Well, it's dangerous. Running an unfused wire from a battery means it can, in effect, deliver an unlimited amount of current up to the batteries capacity. Now we know that isn't what happens with electricity because before you get to 'unlimited' amps (or over 9000 :D ), you get warmth.... then melting.... then fire. You turn your wire into a fuse.

The auto shutdown feature is useful for this, because it does power down properly, not go into standby. I suspect that won't be your problem though. What USB devices are connected to it? I wonder if something is preventing it from entering a deep sleep.
[Android Head-Units] valient1008:
Hi skezza

can you tell me how can i use tasker, you know, iam new in android, all my life i have iOS.

So can you tell me the steps for do that you told me?

thanks!!!
[Android Head-Units] jagman96:
No USB devices! Not sure which app is keeping it from going into standby. I'll rewire it through the fuse box to be safe. Which fuse do you recommend tapping into?
[Android Head-Units] skezza:
https://xdaforums.com/showpost.php?p=76926343&postcount=99

If you're used to iOS there's a small learning curve with Android but you'll quickly begin to prefer it to iOS. I certainly did and I don't think I'll ever go back to Apple now. Customer lost on their part.

I don't remember which one I used..... pretty sure it's discussed on this thread though and I copied someone else. I used one of the central locking fuses.
[Android Head-Units] Elmore78:
Guys I have solved the issue with the music cut out for those that may be interested - go to Settings>CAR settings>Extra Settings> Reversing Volume.

By default this is set to 'off'. You would assume that this switches off the parking sensor sound but actually controls the volume dip when you put the car into reverse.

Switch in to 'On' for no dip in volume. Or you can set the volume dip by various degrees from Attenuation -1 to -9. Have set mine to -1 for a tiny dip in volume and all working correctly when tested this morning with Spotify. Happy days :)

Seems fairly obvious in hindsight but wrongly explained in the useless manual!

Here's where I found it - its a thread for the Pumpkin HU but basically the same OS by the looks of it -

https://www.autopumpkin.com/forum/viewtopic.php?t=647
[Android Head-Units] Elmore78:
Is anyone aware of a way to disable the parking sensors completely through the HU options without having to cut any wiring? They're hyper sensitive to everything and the noise is driving me slightly crazy.
[Android Head-Units] skezza:
Yeah I've noticed they're more sensitive than OEM, but I'm not sure it's worth disconnecting them lol :D
[Android Head-Units] skezza:
So there's a new MCU... 2.93

https://docviewer.yandex.ru/view/0/...mcmFtZSI6ZmFsc2UsInRzIjoxNTM4NTYyMTE1NzY3fQ==

Has anyone tried this yet?
[Android Head-Units] Elmore78:
Yeah I know skezza, probably not the best idea :) It's super annoying when you have front sensors, as I often park near to a wall outside my house and they will not stop bleating at me until I turn the ignition off even when the car is stationary (E91). No differentiation from front or back sounds so it just winds me up, and doesn't really serve its purpose as a warning sound. Im assuming you've not had this? I think the connection was loose for my PDC on off button (connected to the a/c, rerouted to ashtray), have taken the whole lot out and refitted, so if it comes to it hopefully I can manually turn them off and on if they're bugging me. Not the best fix and never needed to use it before, but hey...
[Android Head-Units] jerkeife:
I have not but Abby (Xtrons) did have me update my firmware in an attempt to correct the time issue. I am happy to report that my time updates via GPS every time I turn the car on now, without root. This is the link to the firmware she sent me.

https://1drv.ms/u/s!AjrY0uqbW_kBklRpld7xEiS8BqW-
[Android Head-Units] skezza:
I would say those are fairly big improvements that might actually justify the update. The only problem (for me I guess) will be that I lose my Whitelist'd functionality and any modifications that I've made. Not the biggest deal in the world though really.... something I could easily fix again with an hour or so. Might install the update in a few days :)
[Android Head-Units] skezza:
Still yet to update lol :D
[Android Head-Units] Badboyhamsta:
I updated in the hope that I'd be able to connect my Bluetooth game controller to it successfully. But alas, even though it sees it, and apparently pairs with it, it never actually connects to it. It connects fine to my phone. Any ideas what's going on? Have I missed something?

Further to this, how many people are actually on the Malaysk rom? Im thinking of giving it a go and seeing if its any better
[Android Head-Units] carloperatoner:
Hal9k Rom

I just upgraded to the HAL9k Rom v 3.0 from Malaysk V2.0. I would highly suggest that you update to the HAL rom. Everything is working smoothly. No canbus synchronization issues, it's fast and my steering wheel keys work every time. The only challenge is getting a new launcher in place, actually not that hard really. Just need to install one of the canned ones in the rom and then switch to the one that you downloaded.

I am disappointed that some of the software is not functional. The only door that shows that it opens is the trunk. Not a function of the unit, just the poor implementation of the software. Now that things are working better, I hope to develop some tools to control more features in the car. Heated seats, locks, lights, etc. It will likely be some time before I get to it, but now really happy with the investment of time and money on the head unit.

If you guys have any suggestions on canbus control apks, I'm keen to try new stuff.

Carlo
[Android Head-Units] Badboyhamsta:
I'm literally just setting up my system again as I decided to try the Hal9k rom. It was super easy to Install compared to what I read about malaysk. I still have the same Bluetooth issue however so it seems its just not something the Unit is capable of. Like I said I've only had it on around an hour but so far it's nowhere near as ugly and as much of a faff as malaysk looks, and so far it seems to run smoother than stock. Lots more setting up / testing to be done yet though, but I am hopeful.

My usual launcher was carwebguru but I may try FCC launcher because of its live map widget, hope either of them work. :good:

Hello,

I have XTRONS PB7890BP. I also had a problem with saving radio stations and playlists on the player.

Help me change my settngs: in factory settings change power status to memory of last status and ACC OFF to 30sec.

Everything works (steering wheel, radio, time and date, ...), but it hurts the radio every time you turn on the android - it's slow.

Help connect long yellow cable to the battery? I'm afraid - to have a radio on a battery - ontinuous energy consumption.

How do you get it from the car settings? After disconnecting the original radio I do not have how to set the car parameters (door lock, 24h time, ...).

On the radio I have 24h format but on the dashboard shows me 12h and I can not change it. - Should not it allow radio?

Steering wheel works well.

Thx for answer.

[Android Head-Units] wooshman:
Hi

Well done [MENTION=627785]skezza[/MENTION] for such a comprehensive thread and to the others who joined in with input, testing and findings. Your original work and contact with Xtrons make life easier for everyone else down the road due to the upgrades / fixes.

I am now looking at buying the Xtrons PE9890BPL 9" head unit. Would you still say this is well worth the money skezza? On Amazon for £250 at the moment.

Would the ODB connector be worth buying too?

I am looking at getting the reversing camera but I am new to this side of things and know nothing about relays etc. If I buy a third party number plate camera, will the power from the unit, as other have said is there, work with a third party camera?

Does the DAB radio dongle work well?

Has the fitting alignment been improved any or anyone managed to get it flush yet?

Thanks in advance.

Please help me !!!

Hi I hope you can help me with my problem So I've bought a new GPS radio for my bmw e90 325i xtrons there is a CanBus while everything works very well except for the multifunction steering wheel buttons because I have a problem and indeed the volume Button must always be typed to increase or decrease the volume before I could hold the plus and minus buttons moved to quickly down high to regulate that does not work anymore !! Is there a way the canbus the included was to learn or program ??? If so, I would be very happy !! Or any firmware update or would it work as another canBus from another manufacturer? Please help please:confused::crying:
[Android Head-Units] mapleridgebc:
great thread.
[Android Head-Units] Z1rcon:
Really useful thread this thanks.

Some issues / advice I have to throw in:

1/ Does anyone else have an issue with the traffic announcement soft button on the FM radio when after pressing it goes searching through frequencies and never stops?

2/ Mine auto dims when the lights turn on but it is still very bright at nigh if you have something white on screen so I have set my home screen to have PowerAmp audio widget controls in a basic layout colour coded to my Orange dash light with a dark background. This makes it much easier to drive at night.

3/ PowerAmp is waaaay better than anything that Xtrons have loaded to control music and allows you to adjust the sound quality to a pretty reasonable level on the base stereo system.

4/ If you set the shutdown timer to 10 minutes then you font have to wait for the system to cold boot after getting petrol. This also means your wheel keys will work without having to wait for the boot sequence.

5/ I have sourced different screws than those supplied so my unit is rock solid and aligned vertically between the unit and the heater controls below.

6/ Be careful to align the a CD you put in to the incline of the drive slot. I destroyed my TopGun CD by putting it in horizontal as the case scratches the underside badly.

7/ Can anyone get the steering wheel key programmer software to work? Mine doesn't and so to advance a song I have to push down
[Android Head-Units] Carlosjpt84:
steering wheel controls programmer doesnt work for me either. i have just gotten used to pushing down for next song.
[Android Head-Units] tro_m:
Does your reverse sound and climate control visualisation work? if yes, which canbus version did u select in factory settings?
[Android Head-Units] tomf90:
Same issue happening after two years?!

Just read through all 23 pages.. finally a thread about this unit with the same issues as me!

Unit arrived today and I began installing it. First time I switched it on it loaded fine, no radio stations but could connect to my phone and play music. Turned the car off, now it won't even turn on.. do you think I also need to get a replacement CANBUS connector or just change the settings for the shutdown time thing. If one of you live in Hampshire, UK, could you PM me, I might need a hand as once I've got it working I'd love to be able to get it to do all the stuff you've managed to get it to do. Thanks

Update: Its blowing fuse 14 for some reason. If I put the old stereo in with a new fuse it works. Plug the new head unit in, blows the fuse again after turning on for 2 or 3 seconds.. any ideas why?

Update 2: Worked out why I kept blowing a fuse. It's working now, radio still isn't great but it's working. Now to read back through and do some of the mods you talked about! Anything anyone would recommend?
