Don't know if I can justify buying a flat bed sander for this one temporary fix. ;)

It seems to be a problem only a handful of people are having. Very frustrating.

Tried everything..

No auto sleep after upgrading erisin 3015 with px5 board.

Tested malaysk Rom, actually on dasaita ha stock Rom.

Tested several mcu.

Tested several wiring options in vw Touran.

No auto sleep.

May it depends on the rom?

May it depends on...?

De installed head unit and px5 board and attached again to be sure it depends not on contact issue.

No auto sleep.

Getting crazy.

Using ha Stock Rom from 03.08.2017. with HA 2.59 to get best compatibility.

No auto sleep.

I am very frustrated.

Updated my unit yesterday and btw all works great. i took apart the heatsink screw and fitted perfectly. (i think i have broken the internal mic because no sound on it, problems taking apart the radio). I also take off the DVD because i dont really use it.

Maybe the autosleep depends on the Canbus or something. I updated the MCU from KGL to HA and then replaced the Som and i have the Autosleep option. (Before changing the Som i had the option of 10 min-2 hour shutdown dealy).

[MTCD Android Head Units General] pinkpanther28:
I offered to pay $80 usd but I just got the same reply again to cancel my order. I showed how I did buy a headunit from them before the upgrade offer and it would work with mine. My guess is they have no products, just a middleman that forwards the order to be filled. Just a couple more days before my order gets auto cancelled.

The px3 to px5 should not be limited to HotAudio MTCD. The px5 chip works on all px3 MTCD with RK3188 CPU
[MTCD Android Head Units General] Naglees:
Great, I was quoted $95 + shipping when ordering multiple units, so maybe they're starting to open up about shipping the SOM separately as an upgrade.

Thanks for the info dongali, I was under the impression that only specific PX3 could be replaced with a PX5 based the SOM type, that is good to know.

So I’m not 100% clear on what is happening here.

Winston are selling PX5 boards to individuals or there is going to be a group buy?

And we are 100% confirming that board can replace any PX3?

I was going to put together a group buy, but they would only sell to one person who then would have to distribute it to everyone (which makes sense). At the price they quoted me... $95 per/unit + shipping ($45 to me) and then additional shipping costs for everyone in the group buy. I think it would come to like $135 a person which was not worth doing if Winston was offering it for so much cheaper.
[MTCD Android Head Units General] typos1:
It sounds like you have an MTCB/C unit (see settings/about device to check) which means you cant upgrade.
[MTCD Android Head Units General] Skrallex:
I am also very interested in a potential upgrade here if possible. I have the MTCD with the pin-header daughter-board setup, which is easily removable, I assume the RAM is also on this module? I did not have a proper look when I had the unit open to install the heatsink onto the CPU (Australia, so high ambient temps during summer, sometimes car gets up to 50 degrees celsius in the sun).
[MTCD Android Head Units General] markze:
I'm also interested in the PX5 for a Witson unit, also located in Australia.

I have been messaging Witson the last few days and they recommend that I buy a new head unit. Glad I found this post because I have forwarded them the video saying I want the board!

So if you own like an Xtrons 1GB version, you can just swap out the board and it'll work? Or is this only for a specific product?

No need to ask that question if you read the thread !!

There are no "Xtrons" units - Xtrons are a seller, they sell units from several manufacturers, the letters after "MTCD" in settings/about device will tell you what version you have.

Went to my car with my screwdriver and try again.

Installed the PX5 again and tried with all the BT options in the factory settings with no luck. No WiFi neither BT work. The weird thing is that it works with the PX3 on the same BT setting on MD725 but it won't work with the PX5.

Any suggestions?

BR
[MTCD Android Head Units General] typos1:
That is weird. I can only suggest [MENTION=4974080]marchnz[/MENTION]'s Cross Compatible MCU thread to see if another MCU type will get it working.
[MTCD Android Head Units General] hmotwr:
Thanks for your response Typos, I just noticed something though, When My PX3 board is installed, the BT options on factory settings is WQ_MD725, when I install the PX5 board the WQ_MD725 is not present as an option, only MD725. My guess is that the WQ_MD725 option is a cobined BT/WLAN module you talked about on previous posts.

I have been installing different ROMs and I can't get the WQ_MD725 option to appear on the BT options on factory settings.

[MTCD Android Head Units General] Cid6.7:
Thanks for the link, :) I think I'll wait & see if they'll drop in price. For $150 CDN I'd spend the extra $$ & just get a whole new unit.
[MTCD Android Head Units General] typos1:
Waste of money unless youre gonna buy one with a different facia.
[MTCD Android Head Units General] schriss:
Looks like it's PX3? Still, it's 2GB RAM and Android 7.1 so it's all that matters. Any BT or WiFi problems to expect? Will it change my radio from MTCD_KD to something else?
[MTCD Android Head Units General] typos1:
Yes you can buy both the RK3188/PX3 with 2Gb RAM and N or the RK3368/PX5 with 2Gb RAM and MM, both are the same price.

You will still have an MTCD unit because youre not changing the motherboard.

There are some reports of BT sound issues (but there are for all MTCB, MTCC and MTCD units), these have been traced to an RF shield near a screw that holds the SoM in on octacore units.

Not heard anything about BT or Wifi issues with teh RK3188/PX3 2Gb models
[MTCD Android Head Units General] schriss:
I see, there is PX3 with quad-core and Android 7.1 AND the other one octa-core (assuming a bit faster) but only Android 6.0

I wonder which is a better choice, why there is no PX5 with Android 7.1?
[MTCD Android Head Units General] typos1:
Nougat is in development for the RK3368/PX5.

Personally I think the RK3188/PX3 with 2Gb is good enough, I d kinda expect at least 3Gb of RAM with an octacore processor, but the RK3368/PX5 is perfectly good.
[MTCD Android Head Units General] Cid6.7:
Whats a waist of $ ?

Spendin the extra $ for a whole unit?

Or the chip being $150 lol
[MTCD Android Head Units General] schriss:
I think I will go with PX5 then, simply because I already have PX3 hardware: CPU/Graphics (just less RAM) and benchmarks from other posts did suggest more than 2x speed increase in CPU/Graphics alone and more RAM on top of that means even faster overall. Also its easier to get 7.1 later via software update than update CPU/Graphics some time later. And I kind of don't see the difference between 5.1, 6.0 or 7.1 - their stripped down android seems to always look the same and Bluetooth support is always bad. So even if I will be stuck with 6.0 for long time, I don't think I will be missing anything at all.
[MTCD Android Head Units General] typos1:
Yes, as both SoMs are the same price its seems better to go for the octacore.

What do you mean about BT support ?

---------- Post added at 10:55 AM ---------- Previous post was at 10:51 AM ----------

Spending money on a whole unit.
[MTCD Android Head Units General] schriss:
I mean it's almost non existing, many devices can not be paired at all, it only supports very few bluetooth features when paired with a phone. I bet Bluetooth PAN does not work. It feels almost as if Bluetooth was built on top of android. But as long as my phone and my OBD tool pair like they do now, I'm fine with it. Oh and that thing with some apps which complain about Bluetooth not turned on, when it is on. I get this whenever I get into Torque settings.
[MTCD Android Head Units General] typos1:
The MCU controls BT, so you only get BT calling and AD2P, thats why there arent other features like filetransfer etc, its effectively a car handsfree BT kit, thats all - Android tablets and phones dont support controlling another device with a phone, they only support having their phone app being controlled by other devices. This is also why some apps will complain that BT is not turned on - Android has no BT on these units so those apps cant see it (read the MTCB and MTCD wikis for more info). Personally its never bothered me - as long as I have BT handsfree I m ok, I use usb for OBD (its faster, more secure and BT is designed for when one or both devices are going to be moved around and both the headunit or the car's ECU are fixed in place so its pointless) BT streaming I use occasionally if passengers want to play something and I can live with using the sd/usb for file transfer, anything wireless (BT, wifi etc) is never as fast as wired.

You could, theoretically at least, add a BT dongle to the Android side of it for other BT functions, but youd probably have to add a BT stack to Android to get it to work, some units like the Newsmy Carpad have 2 BT modules, one MCU controlled for the handsfree and the other controlled by Android for all the usual Android BT features.

I have a lot of experience with these units and reading/posting on these forums and I ve never experienced one that wont pair and maybe once or twice read about a problem with paring with an iphone. Have you gone into factory settings and made sure its on the corect BT module ? What trouble are you having ?
[MTCD Android Head Units General] schriss:
For me it's all good as long as my phone pairs and OBD works, I know it's not native bluetooth so I take it as it is. My OBD module is bluetooth, but very good, it's OBDlink MX, reads more protocols and is super fast compared to generics (I do have 2 other cheap OBD readers and I did read rate test in Torque or other app, HUGE speed difference, something like 10x-100x times faster) and was expensive so I'd rather keep using it. Luckily I got it to work, as long as it all works at least the same way on upgraded PX5 I will be happy.
[MTCD Android Head Units General] erronr:
Hey, thought I posted this yesterday but I guess not. I upgraded my px3 1gb unit to a px5 yesterday, after ordering on aliexpress. It is titled "FOR WITSON Coreboard Octa-Core +2GB RAM +32GB Flash For Android CAR DVD [Android 5.1 system Upgrade to Android 6.0 system". Cost $115 and I got mine in about two weeks. Everything works great. BT(odb with torque), wifi, radio, gps.

It's a night and day difference on speed and responsiveness. On PX3, id open maps and it would take about 5 mins before it would catch up enough for me to input the address to start navigating. PX5 is about as quick as most mid range phones these days.

Upgraded my bmw e90 android unit if anyone with one is considering, plugs right in.
[MTCD Android Head Units General] randeez:
Alright guys... I'm trying to find the "Shut down delay timer". My unit has been good since the PX5 swap but it is now starting to do full shut down more often then going into deep sleep.

I can search settings, it shows the tab for shutdown delay, I click it and it brings me to the "Extra settings" menu but the shutdown delay option isn't there.

I've played around with the factory settings to adjust a few things so I'm not sure if something I toggled has hidden the menu.

[MTCD Android Head Units General] Phredeee:
I am about to pull the trigger on this for my Joying branded HU RK3188 currently with 1.90 JY MCU running a Malaysk ROM. I plan on going to the HA 2.58 MCU also

My issues are:

God Awful Poor BT audio quality with only front right speaker (MCU?)

LAGGY to the point of volume freezes

FM pre-sets are useless they only display part of the streaming RDS (ROM?)

I would like it if A2DP mode remained active after cycling the power but not a big deal (Tasker)

DVR software does not always start.

LAGGY

Screen brightness is lacking at times

This unit has a custom fascia that matches the car, 2012 RAV4, well and has a CD slot I never use.

I would like to correct these issues understanding screen brightness is not going to change. What about the other things?

I would love to be able to use the unit for Google maps while running the DashCam DVR and streaming audio via WIFI thru a phone hotspot. Too much? I currently use A2DP and the rest on my phone. Manually starting the DVR on the HU..

If it were not for the OEM look of the fascia, including hard knobs and buttons, I would replace the entire unit with the latest and greatest. I wouldn't mind even swapping entire motherboards if I could find one that would fit and interface video wise. Life is a compromise, I just would hate to drop $120 on the upgrade and still not have a working BT phone or have a better gut and replace option available for a few dollars more.

I have a dash cam, backup cam and interior cam that I run thru the A/V in. It is a little glitchy about the audio source sometimes if I go to the A/V in but it does work. I must say the GPS and WIFI are strong performers.

Thoughts, Comments, Advice?
