[MTCB Android Head Units Q&A] ImitableBeatle:
I got an app called "GPS Odometer" by "GPS Tools" from the play store, installed it in system/app folder, and used a root tool app to force open the app after the HU boots up and it's been working perfectly. Sadly I can't put in my current Odometer value.

I did find another app called "DS Speedometer" by "DS Software" and on that app I can put in my current values and it continues on from there. Problem is you must upgrade the app to paid version to use that feature.

I don't mind paying the upgrade charge for the app but I don't know if it will work on boot and will continue to run in the background while I'm driving without shutting down.

Check my post #17975 http://xdaforums.com/showthread.php?p=62618210

I'm using the stock ECU. I downloaded Torque and bought one of those Bluetooth OBD2 ELM327 scanners but I can't get it to work with my car. I got it working on a Honda Accord but it just won't read or connect to my ECU. If I could get it to work that would be perfect.

***Beer :beer: money for whoever can get Torque or another app to read my ECU.***

Off-topic: My car is completely stock. It only has about 37k miles on it. It's my daily driver but basically for school/work.

How do you get mirror link working? I have a KGL using JY 4.4.4 20150609 with 2.55 KGL1 MCU with sleep and redesigned sound processor from darkleo and my phone is a Sony Xperia Z3 Compact.

I have seen many videos showing mirror link working but none showing how to get it working in the first place. I have gone into settings on my phone, Xperia Connectivity and started MirrorLink but it does nothing at all.

If you need help installing the update.img look on the first post.

That being said,

First, find the latest MCU for your KSP.

Install.

Then, find the latest ROM for your RK3188 1024*600 display.

Install.

Most ROMs already come rooted just download the Superuser app on PlayStore once your done. Good luck :thumbup:

ADB-over-WiFi working

Hey, sorry for the late reply, had to order another one since first one bricked through a ROM update that went wrong... thanks for the help, it successfully connected and working so far. Just another quick question... seems I can backup the device to a file... think there's a way of having it saved as an image (trying to copy entire flash and file system)? I'll also try to get ADB-over-USB working as Oxygen Forensics could get a physical dump from USB and Bluetooth (if ADB-over-Bluetooth is a thing). In the meanwhile, I'll try the commands and see what I can do.

Have placed a diode on the ACC line and no change to the original problem, after the 30sec delay I can lock the doors

Tried the updae of MCU and no change to the door locks but did lose the radio so had to go back to 2.64 to get the radio back.

So I guess I will just have to wait each time I start the car to get the radio etc, still I much prefer to have the Android HU than the stock

I loaded tthe Bluetooth app, then paired the obdII adapter in the settings menu (I believe, sorry been a while since I've done it) I searched, it appeared, I tapped it then hit tthe icon that has a phone icon in thd middle (believe it had a circle with an x in it) then on bootup it would always connect and torque would eventually work fine with no issues, prior to 1.86 my torque would list 4 different devices to connect tto and nnone would work correctly.

I don't suppose anyone has a photo of the two fitting brackets supplied with their Audi A3 stereo? I sent the seller a photo but they are telling me they have sent the correct ones for an Audi A3, and if it doesn't fit I should go to a local fitter to find the correct fitting kit. This doesn't seem right to me, surely a local shop is unlikely to have a kit to fit a Chinese stereo.

I think they have sent the wrong brackets as they don't even fit the unit properly.

Hmm no, I shall give that a try when I get a moment, I did find a version that did work as I wanted but it has a new HUD feature that I can't find anywhere to turn it off, so may go back yo the other version that went full screen and try that entry and see what happens.

Hmm no, my signal is fairly decent, it does have its moments where it fades in and out mind you. I don't have the switching enabled (as I'm not sure which option does that to be honest) and my Rds works, just wish it was inverted with the radio frequency

Hi all, just waiting for a couple of parts (replacement LCD as digitizer gave up, 12v to 5v 3AMP buck converter for the USB mod, soldering kits, and the radio booster for my stock boosted antenna), and I'm hoping to spend the entire weekend next week sorting it all out rather than doing it piece-by-piece.

I thought I might as well do the diode-capacitor mod so as to fix the issue with the unit immediately turning off as you cycle from OFF-ACC-ON. I have an electronics store I can drop by locally for to purchase both diode and capacitor, but my electronics know-how is very limited.. With that, can anyone share a couple of images and specs to the diode and capacitor that I'll need for that mod?

PS I know there's a suggestion to use a solid-type 1000 microfarad cap, but wanting to get a picture of what I'd be really looking for when I get to the store. I'd prefer having a higher-rated diode and cap by the way even if it delays the headunit's shutdown by almost 5 seconds. Better that than buying a lower-rated spec and ending up with the caps not having enough charge to discharge for the HU.
