Xtrons TR100

Processor type- UltraOcta-T8
Android version- 7.1.2

System ver- v9.2.2_20180314.153952_TW2-FD
I have the Xtrons tr100 which has been a very great upgrade from the last unit I had, especially the sound quality. The only problem I'm having is an issue with the bluetooth which will not connect to my obd2. When i search for bluetooth devices the obd2 does show up, when I press and hold on obd2 3 options pop up which are ok, obd2, and cancel. I tried all options with no success. I went into the extra settings and chose bc6 and/or bc8 with no luck. Anything elee I'm missing or could try?

Hi, Your unit appears to be an allwinner unit and so posting in the android auto forums you might not get a response. Here's a starter for you:

Thanks a lot

Hi Marchnz,
you said above that "trigga_b Your unit appears to be an allwinner unit and so posting in the android auto forums you might not get a response." would be better on a different thread why is that?
I have the same head unit TR100 and after searching for Xtrons TR100 I ended up here do you not consider this an android head unit it is running Android 7.1 nougat

BMW e90 keeps displaying metric instead of imperial on start up

I installed the Joying JY-BO124N3 Android head unit which works great. The problem I'm having is the car is displaying metric units on start up. To fix this, I have to go into the head unit settings and change to imperial/American units which will then display the correct units on the dash/climate control. The headunit itself always displays the correct Imperial units (mph, F, etc). I contacted the manufacturer who said it wasn't possible to permanently change through the head unit. The Eunavi Android head unit in my Toyota doesn't have this problem so I'm assuming the problem is with the BMW. Is there anyway I can permanently program/code out metric units so only Imperial information is displayed on my dash?
I did a review on the head unit and show this problem at 3:23:

Bump

Anyone?

I can’t help other than to say I had the same issue with my BMW E90 and an Eonon unit so it seems like this might be an E90 thing with these aftermarket head units?

Ah, thanks for the reply. This is super helpful. I'm just relieved to hear that someone (unfortunately) had the same issue as me. If my Joying and your Eonon are doing the same thing, then I can pretty much narrow down that it's on BMW's end.

"REAKOSOUND" 9" head unit no sound from any app

Hi, I got a "REAKOSOUND" 9" head unit for my 2005 Citroen C4 Coupe, it has "android 10" or an imitation of it. I have no sound coming from the device (tried Youtube, radio, music app, and others. I manly want the main radio cable connection for sound, not RCA although I have tested the RCA connections which have no sound either.
What I tried:
- Reconnected wires multiple times
- Hard reset more than 3 times
- Seller provided "update" that did not change anything
- Tried an RCA speaker into RCA "Aux R Out" - no sound at all (Speaker from a 5.1 PC speaker set)
- Oscilloscope measured from the CANBUS/radio harnes from one speaker line coming out the head unit: 60Hz sine wave less than a millivolt, think that means no sound coming out the Head unit output.
- Tried all avaliable CAN Type options for citroen, steering wheel buttons work with all of them, no sound with any of them.
- Volume has been set to max "40 units".
- Original radio still works.
- Tried to look for some apps on google play that may control sound output, found only one, did not do anything.
- Tried all the apps: Radio, Music app, BT music, Aux mode, Spotify, Youtube, phone call (mic works) - no sound output from any app.
- Canbus works, the steering wheel buttons work and travel distance data is being transmitted to the head unit.
- Tried asking for OS update files from other Ali sellers, all refused to share (not compatible and such).
What I noticed:
- All the Citroen Canbus models in the head unit settings have 2008-2015 models, the ad said compatible with 2004-2008 car models - maybe the Canbus is incorrect for my car (I have Raise PSA-RZ-15)?
- There is no AMP wire coming from the cars side.
- There are no audio settings in the Head unit, Only an equalizer and a balance setting front to back and left to right, that's it. Other head units seem to have more options in the OS.
My Questions:
1. Should audio work without CANBUS?
2. If there is an amp in my car and it communicates with CANBUS, can I turn it on without canbus? (I have not seen an AMP wire in my car - nothing blue with a white stripe or similar)
3. Does anyone have any suggestions what to try to get any sound?
4. Are there any other car androids I could install and test?
a. (EDIT: I found this post on XDA, and this post, and this post, as far as I understand there is an MCU and a MTCD, one of them carries android the other is like bios that bridges the car system to the android, in my case, the sound issue could be from either of them)
5. If it's not android, what hardware should I check? I am decent with soldering and similar electronics, just Head Units are new to me.
Device info that I could find:
Brand: REAKOSOUND

Hi new member, posting in MTCD general forum.
Is it an MTCD/E device?
Your post is difficult to follow without formatting and spacing.

Thank you for the response. I improved the format, hope it helps. I unfortunately don't know what MTCD/E means, I did not find anything on google. Therefore I am not sure if I have an MTCD/E device. I am familiar with electronics but head units are new to me. My first experience with them has been severely disappointing. Hope I can get this unit working and learn something along the way.
What does MTCD/E mean and how do I know what device I have?
If I am in the wrong place, is there a better sub forum on XDA I can post my question to?

Hi, I have requested a Mod moves to [Android Head-units] forum.
Your post is likely to have visibility there. You'll also find your device listed/discussed there - mcu version.

Loss of reversing beeps with Android PX6

Hello,
By installing a PX6 car radio on a 2006 Peugeot 407 coupé, I lost the following functions; Back-up beep forward and Back-up beep back.
The reversing beeps are materialized by a drawing of the car on the screen and green, yellow and red lines depending on the distance from the obstacle. (cf attachments)
Is my CANBUS system well suited/adapted to the car?
Is it possible to reprogram it?
Do you have any other solutions to offer.
Thanking you in advance for your help.

Ok Thanks for the explanation

@marchnz What’s the point between the MCU version and the lost of fonctionnalities like the beep forward and backward.

Finding the exact type of head unit, placing post in correct forum, getting question exposure to users of similar units who might know menu structure or provide assistance.
Dumping a question in a forum is likely to result in zero responses, you may as well post the question on a dating site

It seems the post was place in the correct forum, in "Head Units",
but Thks for the moral lesson, it's always a pleasure.
this will help to solve my problem for sure.
you'll find the new post in the right category i hope...
