Hi everyone,

Its been a long time since i made any updates to my KLD unit. I dont remember which rom i'm running(updated around 4 years ago). I know my unit has rk3188 cpu, 800x600, and is MTCB-KLD-V2.64. Im looking for a rom that has a newer refreshed Bluetooth Audio GUI. My current one does not show what the current song is playing. Any suggestion on what I may be looking for?

ThankS!

[MTCB Android Head Units Q&A] Nightwchtr:
Evening all, apologize if this was asked before but haven't been able to find it. Question is, is there an app that can turn on the back camera (reverse) without going into reverse? I thought it was frontview.apk that was modified to do it but after upgrading my HU after 2yrs the new version doesn't do it. Thanks:)
[MTCB Android Head Units Q&A] typos1:
It cant be done with an app, it can only be done by hard wiring a switch into the cable that goes into the reverse light (its this that triggers the cam to come on).
[MTCB Android Head Units Q&A] Nightwchtr:
Actually not correct and reason why I say that is because I had it a year ago. The person who made the app wrote it through the canbus. (From what I remember and understand) it was able to turn the cam on without being in reverse but the camera had to be on a constant power supply which mine is. Which is sometimes aggravating because I don't drive a lot but every 2 days I have to run the car for at least an hour so battery doesn't die, lol.
[MTCB Android Head Units Q&A] typos1:
Right, well you need to search for a thread about that app, although youve highlighted a massive flaw in that set up, so better to do it the way I suggested - putting a switch in the lead that triggers the camera on so your battery doesnt get drained.

GA5167 dvd android car unit cable pinouts

I bought a used unit without cable.ga5167 eonon

I have a very similar cable from another model that fits but color and pinouts will be different maybe. I need to check.

I looked in online manual and the pinouts diagram of 20 pin connector is confusing me.

It shows numbers 14 to 27 for the wiring.

I need to know pin 1 to pin 20 or a good photo of both sides of cable so I can work it out by colors.

Thanks for any help guys.

PX6 4G internet termination issue

AOTSR Tesla Style Android 8 PX6 Car Player For Land Rover Freelander 2 2007 - 2015

MCUver RL7A_CHUANGT9M_F038PB-SX2_DAC_IV8.6

Everything went well with installation apart from internet connection with 4G LTE. The unit has sim card slot and connects to 4g network in Europe such as Vodafone . When starting the unit I get internet connectivity for a minute or so and then it stops. All settings including APN are fine and the unit seems to be connected on network however when launching play store or web browser there is no internet. The strange thing is that I get connection for a few seconds and then it stops. 4G signal is always ON.

1. Have tried different network sim card

2. Switched off all WiFi and other networking in case they interupt 4G connection.

3. disabled carplay connectivity - unistalled zlink for the same reason

4. Done factory reset

5. Changed 4G Module type in hidden menu (DATANG,COMMON etc)

6. Manufacture support claimed that it should work with european mobile carriers no problem.

May provide more information if needed. I have looked in forum for similar cases and have tried already a few things but without result.

Wrong thread - there are no RK3399/PX6 MTCB/C units, there are RK3399/PX6 MTCD/E units, but your MCU doesnt begin with "MTCD" or "MTCE" so you dont have one of them either. Try the Android Auto general forum.

You find one if you want one.

Yours is so cheap cos its Chinese, if the chinese can make a bluetooth lead that cheap, think how cheap they can make a simple usb one.

I have 2 usb/obd leads, one in the car and one for diagnosing other cars, you dont need bluetooth for diagnosing fault codes with your phone, again bluetooth offers no advantages here either.

But you are free to do what you want, its your life :)
[MTCB Android Head Units Q&A] kuwacs:
Sorry, I forgot to put this in my original post, but the reason I'm stuck on bluetooth is because I already have one of the ELM327 bluetooth adapters. I've been using it with my phone flawlessly, but can't pair devices with my KGL due to the missing bluetooth menu.

Under torque, it lists two bluetooth devices (both just MAC addresses) but neither connects to the car. Searching for the device under the bluetooth app finds the CHX device, but doesn't let me pair with it (probably because it's just a phone/audio control app?)

Any ideas? Thanks!

Questions about HuiFei screens..

So after exploring the settings areas, there are some settings pages i don't quite understand, that i'm hoping to get some advice on.

In factory settings area (accessible via password)..

This screen seems to let me turn off features i don't have.. but the bluetooth and radio options give me some choices; im assuming hardware folks set these to appropriate values and i shouldn't touch?

Blue tooth applications options:

Radio applications options:

Other page.. what is RDS? I think RGB is what enabled the "Elements" page below that is supposed to be for changing lights. Keymap interests me..

Keymap options (now this is interesting because i'd like to remap some keys):

Radio bands.. I'm in America, should i choose America1 or America2?

Element color -- i think this is supposed to change color of light coming out of dvd slot (or buttons); my buttons are painted and dvd light never changes color:

What does Loudness do?
[MTCB Android Head Units Q&A] magnetar14:
Does the radio smell burnt too?

a litle bit, and heat.

Its a renault megane cc.

There are 4 speakers, 2 front ones, and 2 smaller rear ones.

It wasn't loud when it broke.

The only option i see now is installing an external amplifier to avoid using the unit's damaged amplifier, is this a good solution?

So I just got my new mic today. I'll get it installed in a little bit and see if I can post some before and after audio. I did a quick test, and it's better, but not great. My on board mic is completely disconnected and my mic is connected directly to the motherboard. I posted pictures a few pages back for those that missed it.

One thing to note. There's only 2 connections on the stereo, meaning it's a mono connection. I soldered on a stereo wire, and just bridged left and right channels together. On my new mic, it's actually a stereo mic, and I'm wondering if having 2 mics feeding one channel is causing problems.
[MTCB Android Head Units Q&A] xrapidx:

The mic thing is annoying - I haven't ordered a external one yet, waiting on feedback from others.

I literally can't use my unit for calls, the quality is that bad.
[MTCB Android Head Units Q&A] sickbro80:
Well, got my mic installed. At first it sucked pretty bad. Lots of static, and just very poor quality. I decided to go remove one of the two stereo wires going to the mono plug and it got much better. I just talked to the wife for 20 minutes or so and she said it sounded good, not great, but good. It's a big step up from terrible.

I took a recording from the internal mic, and I'll get one from this setup and post them when I get a chance. Probably tomorrow.
[MTCB Android Head Units Q&A] xrapidx:
How can I identify if my unit is mono or stereo? It has a jack for an external mic - so I'd prefer to order the correct one.
[MTCB Android Head Units Q&A] dcmouser:
I would really love to hear if this trick is confirmed -- my microphone (both internal and external) yield such poor audio that it's essentially unusable.

People have also suggested that they have heard rumors that upgrading the firmware from v1.77 to 1.86 *might* *possibly* improve the microphone -- i'm waiting for a bit more of a definitive answer before i try upgrading.

Fitting a wireless reverse (backup) camera to HuiFei KGL

I've been supplied a reverse/backup camera with wireless transmitter and receiver, it appears to be unbranded but in the camera instructions it refers to Navinio.com. I've uploaded a pic of the wiring diagram which is on the head unit. My question is which yellow connector should the video out from the wireless receiver connect to please?
[MTCB Android Head Units Q&A] sickbro80:
If I had to guess, I would guess camera vin., which I'm guessing is camera video in. Won't hurt to try them until you find it though. Just wire it up, throw on your parking brake and put it in reverse and see when you get a signal on the monitor.

Hi guys, I have two questions:

First. I have buy this unit for Audi ( a3) the board display doesn't work. It's does possible is a problem of wire connections?

In the instructions there are two wires named "steering wheel control line " the I don't have connected....

In fact my steering control are not managed in the system settings...

Second:

The quality of internal Mic is very poor...

I have original Audi Bluetooth interface... If I use original Bluetooth people can hear my voice but I don't hear anything...the android stereo dont received the audio signal...

Otherwise I would be use the original audi Mic with android unit but there aren't the wires,is powered by canbus... Anyone have a idea?

[MTCB Android Head Units Q&A] agentdr8:
There's a couple ways you could do this that I can think of:

- Use Tasker or Automagic

- Write a small app to register a onboot broadcastreceiver and fire off a startIntent for com.microntek.travel.MainActivity

- Use Xposed to fire off the same intent after onCreate() method is complete in MTCService (this is what I use for XposedMTC autoloud)

You all talking about OBD with Bluetooth or USB. Has anybody test it with a WiFi ODB Adapter and Torque?

Depends on which 'America' you're in. United States, or North/South/Central America? :)

If you're in the US, you want 'America2'.

You can use America1, but it will then let you pick even-digit Hz fequencies, which won't do you any good. (i.e. 99.8..)

Car dvr port

Has anyone connected a car dvr to the dedicated port in the back? If so, which. If not, what kind of port is that?

---------- Post added at 03:47 PM ---------- Previous post was at 03:37 PM ----------

This unit is not capable of sending data to the console display. I'm not sure if the software is coded to even try, but even if it is, from looking at the harness, I don't think the wiring is in place to do so.

As for factory Bluetooth, there might be a way to tap into the audio out and get it to the head unit, but the experience would likely be poor. Since it isn't integrated with the unit, it won't know to stop whatever other audio is playing and play the factory Bluetooth output. If anyone makes this work, I'd love to hear how.
[MTCB Android Head Units Q&A] agentdr8:
I should have made it a bit clearer, but the utility to write the kernel image is already supplied on the headunit. It's the flash_kernel binary, found in /system/bin. You just provide it what you want to flash as the first parameter (the word kernel) and then the filename of the item to flash as the 2nd parameter (kernel.img, or whatever yours is named). There wasn't any output after I ran the command. It just returned to the root prompt. And that's when I rebooted.

Once it's back up, you can verify it worked via the command "uname -a"

[MTCB Android Head Units Q&A] sickbro80:
So about the microphone talk. I ended up actually adding a mono microphone jack to my unit. The rear of my unit had an extra couple of holes for whatever addons they may have offered (tv tuner). So I picked up from radio shack for about $5 a "panel mount mono 1/8" phone jack" (item 274-0248). This is really what should have been put in these in the first place, but its basically a jack that allows me to hook up both mics. When nothing is plugged in, the onboard mic works. When an external mic is plugged in, the onboard mic is disabled and the external mic takes over.

I was in a bit of a rush last night and I guess I forgot to take pictures. So far it works, however now my stereo microphone is bridging both mics to one channel as I had before. This is just how stereo headphone jacks interact with a mono jack. So I need to dig up a mono mic to really test it.
[MTCB Android Head Units Q&A] typos1:
These units communicate with CAN Bus via an adapter, these adapters are supposed to be dual channel, but in several people's experience there can barely manage one way comms, let alone 2 way.

A few people have posted about trying to get Android to directly communicate with CAN Bus and I m interested in this as well, it shouldnt be too hard in theory at least, but would take some development.

As for Bluettoth audio, its no secret how I feel about using bluetooth for obd on these units and I have a similar opinion with bluetooth audio - AFAIK you cannot change folders with bluetooth audio, so all your music has to be in the same folder, plus AFAIK you can only play mp3s, which are lossily compressed and therefore offer pisspoor sound quality, so I would say that youre best off plugging your phone in via usb, that way you can top up its charge at the same time. Again, this is my opinion, no one has to take any notice.

TomTom GPS software

I used to have a stand alone TomTom that I can probably backup and pull the software/maps off of and put on an SD card. Will this work>?

[MTCB Android Head Units Q&A] agentdr8:
Unless your standalone TomTom unit is android-based, you would need to find an android version of the maps and app. Try this.
[MTCB Android Head Units Q&A] kwalsh24:
You would likely need a tomtom android edition, as likely the one you have is wince. Google is your best friend for this, as you'll likely have to either buy or 'borrow' a copy.

Err sorry didn't see someone answered the question haha

I just seen the tomtom for android and I may hahave to try and switch, as it seems to be similar to Igo, in which igo is frustrating me with tts, mind you I think its more the radio app that's being a pain over Igo, but I do like change.

Also update, my radio apk has once again stopped mixing GPS sounds. Turning off the GPS mixing & rebooting then re-enable doesn't fix the issue either, only way to fix it appears to be a clear the apk cache. This is my biggest issues with this radio! Hope the new firmware fixes it, once they release it that is.
[MTCB Android Head Units Q&A] DWhite456:
ok, thank you. Sorry for the confusion. Will I need to load it on the SD card or will it just be another app on the HU? If yes for the latter, will I need a way to switch the default GPS program when selecting the GPS button on the HU?
[MTCB Android Head Units Q&A] kwalsh24:
Yoy would likely do both, load the apk, then it will read off the Gps SD.

Seriously?

I would probably break the Ultra big USB-OBD-Plug every day with my feet when entering the car.

Do you really try to tell me a USB-Cable is easier to hide than a Bluetooth-Donle?

USB: http://img.efox-shop.com/3rd_gather/s/283/059525.images.400x400.jpg

BT: http://i00.i.aliimg.com/wsphoto/v0/...er-wireless-elm-327-interface-vgate-smart.jpg

That might be true but that's not what I was talking about. I was talking about practicality. And it's a fact that it's easier to hide and use the BT one without loads of work. Oh and cheapes... I doubt... It's basically about the same price...

This is also a statement where you cn see that you'Re thinking too one-way... What If my AP with DSL Modem is on ground floor and my PC is on the first floor? If I have the choice of opening my houses walls just to connect a PC or just use WiFi (which is fast and fairly secure at todays tech) - My decision would be clear to me.

Not meant or understood as rude but as a developer I fully understand your statement. But you are thinking a bit one-way. It might be easy to hide a cable yes, but you have a big plug which probably causes you not to be able to hide the plug at all for example.

And just to clear that up: If you are talking about wireless tech not to be used stationary you should probably also think about OBD not being meant to run permanently connected but just for diagnostocs when needed... :p

As I said: That's not menat to be rude! Just wanting to clear up my point of view.
