Hey guys,

In regards to OBD ELM bluetooth connectivity, the scenario as follows:

Scenario 1:

0. xposed framework enabled, all modules enabled

1. elm connected to the odb port

2. bluetooth settings - pin set as the elm -in my case 1234

3. rescanned all bluetooth devices

4. device available, device name OBDII - cannot pair

Scenario 2:

0. xposed framework disabled

1. elm connected to the odb port

2. bluetooth settings - pin set as the elm -in my case 1234

3. rescanned all bluetooth devices

4. device available, device name OBDII - device PAIRED - tested in Torque -> WORKS

Afterwords i enabled exposed and no othermodule, that being said, Scenario 3 :

0. xposed framework enabled, but all modules disabled

1. elm connected to the odb port

2. bluetooth settings - pin set as the elm -in my case 1234

3. rescanned all bluetooth devices

4. device available, device name OBDII - device PAIRED - tested in Torque -> WORKS

I enabled xposed modules one by one, till i lost the connection to the ELM adapter, everytime with a full reboot of the unit and restart of the OBD device.

I can conclude that the connectivity issue is related to the Xposed MTC Manager module, as once is enabled the pairing does not work, even if the device is present in the " paired devices " list and not on " Available Devices " list.

Perhaps you guys can confirm this so we can try and address this to MVG-70 in order to find a long term solution.

In final words, ELM327 Bluetooth device is now paired, torque works (i will test with dashcommand as for the moment does not connect to the ECU (perhaps something is fishy in the dashcmd settings)), MTC Manager Xposed module is disabled, once enabled connection is broken again.

Hope this help

Hi,

I have a problem with my back and forward knobs on my headunit and on my steeringwheel as well. When for example spotify is playing a song i can use the knobs to go back in forward in the playlist. When i switch to another app like tuninradio and i use the back and forward knobs, spotify reacts to switch a song and tunin radio does the same. So The problem is that the knobs keep controling the app on the background. Is there a simple explanation for this?

[MENTION=6738895]kumarai[/MENTION], Doctorman sells Joying units and they have not managed to get 5.1.1 working with MTCB units, this may explain why he is a little sceptical .

I opened a separate thread for Lollipop here :

[MTCB Android Head Units Q&A] typos1:
Yeah I know, I was just saying that maybe your slightly sceptical attitude that it really is 5.1.1 is down to Joying not being able to do it, thats all :)

Next question is, will 5.1.1 be easier or harder on resource utilization? I've read that 5.1.1 actually slows down some devices over 4.4.4.

Bluetooth phone call back screen

Hi, I just updated my rk3188 hHU to a new SW (Malaysk) It worked fine as long as I have started to play with it. Everything is ok except when I receive/start a bluetooth phone call. When I start it the screen goes black. I can still hear the person on the phone and vice versa, but the screen doesn't come back. I have to restart the unit. I think it's not normal. Could you tell me how to fix it? Thanks in advance!

Theres no "right version" just try all the ones from your unit manufacturer there are until one works. But to be honest I d forget about the MCU and update to Lollipop, then sort out the MCU problem then if indeed you still have it, things may work ok with Lollipop.

Your problem is that you do not have an MTCB head unit, you are in the wrong thread, you are very lucky, you could have bricked your unit, ALWAYS check wikis and do research about your device BEFORE attempting to flash firmware !! Its clear you didnt even bother to check the settings/about device screen ! If you had you would have immediately seen your MCU type is totally different to MTCB untis.

BT steering wheel issue

Hey all,

I've been using this unit for the past two weeks and just found out this forum, so BIG THANK YOU, my model is "MTCB-KGL-V1.70" I think is HUIFEI because the password 126 to get into the system worked fine, I also checked the excel spreadsheet and it seems KGL stands for HUIFEI.

Anyway, my audio steering wheel controls work fine, the problem is the BT phone controls that are not recognized by the system, I did a video on this and sent it to the seller , however I can't paste it here because I am a new user, however if you can copy paste this into youtube you will see the issue:

Damaged internal amplifier -help

I have a KLG unit since a month approximatelly.

And a week ago, all of a sudden while playing music, i heard a weird noise and there was a burning smell, the front right speaker was buned out/blown.

i took it off, and then the same happened to front left speaker, then rear ones.

My car mechanic says the radio's damaged amplifier is sending more than the necessary current to car speakers.

Is adding an external amplifier a solution? to avoid using radio's amplifier..

Any help would be greatly appreaciated.
[MTCB Android Head Units Q&A] dark alex:
magnetar14, you are the second one reporting such issues here.

Are you able to open and disassemble your device tio check if there is anything uncommon with your device?

Like short-circuit or smilar? check your cable that goes into the radio if there is any isolation poblem, too please
[MTCB Android Head Units Q&A] ssvenn:
Sounds like a transistor is stuck open so that the speaker output is delivering constant 12v or something.. If you have a voltmeter it would be interesting to measure the speaker outputs.

The line level outputs might still be good, but be sure to measure voltage before you plug anything into them. Does the radio smell burnt too?

What car model was this? Do you know the resistance (impedance) of the speakers and how many speakers there are? How loud was it playing when it broke? Maybe the manufacturer hasn't done enough to protect the output stage from overload or short circuits...

I have a GS unit and my Wifi reception drops to zero sometimes when downloading files. It only happens when downloading a file in Chrome or downloading an app from the Play Store. I can stream pandora forever and it wont drop, but I try downloading a large file and the reception drops to zero. Turning wifi on and off fixes it, but its a huge pain. I'm on GS-V1.90.
[MTCB Android Head Units Q&A] ssvenn:
I had trouble getting TomTom maps to download on my Klyde, it needed a 3,7GB map file. It kept dropping out of my wifi even when the car was parked two metres from the access point. Changing the encryption from WPA2 to WEP temporarily fixed it for me. WEP encryption is really easy to break so it's not a permanent solution.
[MTCB Android Head Units Q&A] agentdr8:
That's a pretty good description of the issues most experience with 1.86 on the KGLs. It seems the updated wifi module in the newer kernels messes stuff up when there's a large amount of data to be transferred. If you can find an older version of the GS update image, you can probably extract the kernel and flash it the same way. It's also possible the KGL 1.77 kernel would work on the GS, but unless you've got access to a custom recovery, you may want to hold off until it's verified that it won't soft-brick your unit.

Bluetooth Menu

I know the 1.86 update is supposed to add a bluetooth menu, but perhaps my update didn't install successfully. In the "about" pane I do show 1.86 however not a single thing seems different from before.

I ask because I am trying to set up Torque to run on my KGL unit (in my E39 BMW) but I haven't had any luck.

Also, I know the idea of ID3 tags was thrown around concerning the A2DP mode, but is there any hope there?

So just sitting here at the drive in, my radio just shut down on its own and wont turn back on, however I can get it into recovery. Anyone else hear of such issue ?

Think it must be a fuse or a canbus issue, as even my amp isn't on, and its turned on by the canbus.

Edit

Was a canbus issue, no idea. Tho what hppened. Unplugged the radio hardness plugged it back in and its working again... sigh I hope this doesn't continue. I did secure the connections oje the canbus itself, as they are fairly poorly made from the manufacturer

Use a proper usb to obd cable for Torque - Bluetooth is meant for portable devices, neither your car's CAN Bus system or the Android stereo are portable, Bluetooth is slower, less secure and uses more power, there are no advantages to using Bluetooth in this situation, only disadvantages.
[MTCB Android Head Units Q&A] dark alex:
No advantages except that you don't have an annoying, visible cable hanging around in your car.

For example VAG most likely hat the OBD ports in one of these places:

under the steering wheel, in the rear ashtray or behind the fromt ashtray.

Nissan has it's ports ofthen next to the steering behind a plastic part.

You really think USB is always easier and better? I don't ;) :D
