1. What i need to chose for vw polo 9n3 2006 for can adaptor settings ? I dont recived info from car. Only volt . (I dont have display on board big . i have led information sensor.)

and

2. reversible camera dont start when i put in reversible mod.

How i need to connect or what i need to set ?
[MTCB Android Head Units Q&A] kaween:
Can't help with the Canbus question. My primitive Dacia is Canbus-free. :) But as I understand it, you either try every Canbus setting that the unit permits you and if it doesn't work at all, you'll have to contact your seller.

The second question I may be able to answer : another user had a comparable issue. Look at your car unit, and test what happens if you hook up the "Reverse" control line that comes from your unit to a 12V line.

The radio SHOULD switch to reverse-cam view : if no signal is present, you'll see a black screen with "no signal" or something. If the camera has an active output at that moment and it connected, you should see the reverse picture. This "switch" is realised by the units hardware : no setting/software should be needed. the only stuff you can modify is stuff like "sound while in reverse", "Reverse lines", "reverse-the reverse picture (left-right swap) ect ... but decission to produce a picture and switch to the camera input is hardware-based. That's why this works on most units even when the radio isn't even turned on or the android OS hasn't booted at that moment.

The easiest way to get this to work is to connect the "Reverse" line to the power of the Reverse light of your car, so that this line gets a 12V status whenever you put your car in reverse and the reverse light lights up.

Hope that helps a bit.
[MTCB Android Head Units Q&A] Marius B:
reversible cable for camera it is in canbus , then need to read from can when car it is in reversible mod.

if remove cable from can adaptor and put to 12v+ black display show.

i think that canbus need to set correct for each car. ?!?
[MTCB Android Head Units Q&A] kaween:
I can only say I know several people with Canbus cars where the Reverse-switch-by-Canbus did not work, but forcing it by using the Reverse/Back hooked to the reverse-light line does work.

You're right, it SHOULD work correctly over the can bus, but in real-world situations this fails a lot of times, probably due to the only-so-and-so compatibility of the canbus box itself. It's not the radio which is at fault.

What you're seeing there is typical of that behavior. Be sure you will have reverse image and automatic-when-in-reverse if you connect that reverse-line to the reverse light of you car.

Havent you tried the modded KLD Launcher 4.4.2 with bigger date in the first page?
[MTCB Android Head Units Q&A] typos1:
Yep, I have and DSA has as well as eastberkshirecustoms.

Dont think so, you could search Google Play for apps that may do it. If you have to use that cam you could see if there are any RCA to USB adapters available.

I ve uploaded the standard MTC launcher, the KLD launcher and the KGL launcher apps to the fileserver in "apps".

EDIT : sorry, I ve only got copies of the MTC (JY/KYD) and KGL launchers, I ve uploaded them, I ll have to try and get the KLD one tomorrow.

Anyone know how to get into the boot menu on this model?

Driving me nuts how the app partition is 1GB and the Nand is 6GB.
[MTCB Android Head Units Q&A] typos1:
AFAIK same as any other model, but why dont you just install one of DSA's or coudu's pre-rooted/lightly modded factory ROMs with 3Gb app partition ? Or Malaysk's custom ROM ?
[MTCB Android Head Units Q&A] nFKT:
I did search for a bit, can you link to the mod you referenced?
[MTCB Android Head Units Q&A] Udonitron:
Oh?

I think these are pre-rooted, ya?

I know in the system/about it shows the version and mentions rooted in the title.

Does DSA's remain on 4.4.4 and has the necessary radio app etc on it?

Also why not make the entire remaining 8GB as the app partition?

I mean all else can go onto an micro SD, no?

Also, has anyone had these units successfully run Android Auto?
[MTCB Android Head Units Q&A] agentdr8:
I think someone else had a button/knob-less model like yours and added a power switch to it.

You could also try holding down the reset button while the vehicle is off, and then turn it to ACC/ON. Not sure how you select items in the recovery menu without a button though.
[MTCB Android Head Units Q&A] typos1:
Its linked to on the first page, there are also numerous mentions of it in the thread, I cant believe thread search doesnt throw something up. If you google it, it will deffo show up.

Yes, read the first page, it tells you all about it. Everything works, has 3Gb app partition.

If you want more youd have to modify it yourself, not heard of a request for ALL of the ROM to be for apps before.

They are not rooted from the factory.

Dunno about AA, youd have to check the thread on it and see if anyone has.

http://xdaforums.com/showpost.php?p=57379814&postcount=5815

Been reading on this and I cannot seem to find if the cross fader etc is intact in these roms for speaker fading L/R.

Bits of this are confusing vs rooting a phone and installing roms as it says you cannot root 4.4.x unless the image is pre-rooted.

No mention, that I can see, of these images being as such.

Coudu's file link is dead and is not for JY models and it appears Malaysk's file for JY is for 800x480 only.

The img I downloaded here for the JY model is in 2 parts so does the update for this do one after the other or do I merge/rename these two files as they share the same name and overwrite one another upon extraction.

Hi,

My steering controls for the forward and back skip are the wrong why round. How do I reprogram these?

Thanks

The same thing happens to me exactly, both controls are reversed.
[MTCB Android Head Units Q&A] typos1:
The fader is for front/rear, its balance that is for left/right, both work, although its implemented by turning down the output rather than redistributing it - ie, if you want 60% of the output on the rear speakers, it actually turns down the front ones a little, rather than simply putting 60% to the rear.

For rooting KK you need a pre roote ROM, virtually all the ROMs on the fileserver are pre-rooted.

ALL versions of the dualcore software work on ALL dualcore models regardless of manufacturer - ALL versions of the quadcore software work on ALL quadcore models regardless of manufacturer - obviousl you have to pick the correct screen resolution for you unit. You DO NOT need to put a JY ROM on your JY unit, you can put KGL or KLD ROMs on it if you like.

DSA's are the most up to date, pre-rooted ROMs, theyre all on the fileserver.

Put both parts i the same folder and right click "extract here" on the first, it will automatically create an image from both.

Shipping maybe ? Or they could have had a lot of requests so decided to stop selling them at wholesale prices ?

[MTCB Android Head Units Q&A] BusmasterDMA:
It's hard to believe nobody else has found a solution to the problem, since the noise would make this head unit unusable for any audio. But maybe it is only my vehicle that is sending a constant stream of canbus messages about fuel range.

If I were to gain root access, could I then disable notifications for the CanBus app? (The option is currently unavailable.) Or could I find the notification sound file and replace it with a silent file? I'd be happy to no notification sound for any apps, if that were somehow possible.

Edit: I seem to have solved it by using an app called Seer to set ringer volume to 0. But if anyone has any ideas for alternative solutions, I'd still be interested. Thanks.
[MTCB Android Head Units Q&A] Precision340:
Can kernel image be used on KLD units?

Hi all, just got a KLD unit and right out the box the built-in wifi does not work. So I stumbled across this great forum and have been researching and gaining a lot of knowledge on these aftermarket units. The issue with the wifi is that it goes thru the motions of turning on but never turns on and goes back to off. I'm trying to determine if this is software or hardware related. So I come across optx's post about flashing the kernel. My question is, will the 1.77 kernel and flash image work with the KLD units? From my understanding, the 1.77 kernel are for the KGL units? I want to avoid bricking the unit as I know the MCUs are exclusive to the type of units. Also, if anyone has come across a similar issue please let me know what I can try to fix the wifi. Thanks in advance for all the help. This is a great community!

Please, if anyone can help.

UPDATE: Power taster does not work. Volume up and down works. When I use usb keyboard I can select options and when I press Reboot Now, everything works ok and all what I have installed on device remains.

Question is: How can I set boot loader that runs normally without to enter in recovery mode, because I have to use usb keyboard to select Reboot Now?
[MTCB Android Head Units Q&A] typos1:
Is it working ok ? - Everyone else with RK3188 and 1024x600 screen says it does not display correctly.

Just flash a rooted ROM, you wont regret it.

The kernel is totally separate from the MCU and usable on all versions, although that kernel is fro quite a while back, I dont know whether neweer features will work with it.

Pick a ROM with the blue back ground apps if you prefer them or either pick a different ROM and install the apks with the blue you like from a ROM that has them, or decompile the apks with the blue and swap them for the non blue ones in the apks from a ROM without the blue.

You cannot back up the current firmware, but you dont need to - versions going back to 4.2.2. are available on the fileserver. Pre-rooted versions also have 3Gb app of space. Malaysk's ROM has a built in DPI changer, Xpsed MTC lets you set screen res on a per app basis. Viper4Android improves sound quality.

The mic mod is linked to and talked about on the first page and has been mentioned in the thread a zillion times, use thread search to find out more info, adding your unit manufacturer into the search as well to find out how works on your unit type.

You can use ANY ROM as long as it is for your processor (RK3066 or RK3188) and screen res (800x400 or 1024x600), please note currently there seems to be a problem with the display on RK3188 and 1024x600 units. Do you have a dual or quad core unit ? coudu's ROM a little out of date, DSA's are a little more up to date, Malaysk's is a full custom ROM, coudu's and DSA's are mildly modded factory ROMs. BT and radio chip[s are MCU controlled and nothing to do with Android.

[MTCB Android Head Units Q&A] edit:
First of all thank you for the feedback !

I will attach some screenshots of my apps to give you an idea of what they look like (I really like them).

There are a few problems:

1.	I don’t know what ROM has my blue themed apps

2.	I would love to be so skilled and be able to decompile apks and swap them. I don’t know how to do it, never did, can’t say that I will be able to 

3.	Without a backup I can’t turn back to what I had and from what I was able to see most of the roms have different looking radio/dvd/bt/player apps. Tough decision in case my unit needs servicing at some point in time… I have to decide now If I will say goodbye to the warranty in favor of a better software. Without a backup I cannot dive in the image and maybe extract my blue looking apps. It’s possible that I might find it in a rom like you said… I have to look around…. Maybe I get lucky.

4.	I knew about the mic mod but unfortunately I don’t have the tools or the knowledge to make the modifications… I wrote my impressions on the mic so people would know what to expect from this unit also asking if I should bother for a replacement since the seller is in my country and I don’t have to send it away in China. If all the units are the same I would rather not ask.

My unit has:

Android 4.4.4 system

Rockchip 3066 Cortex A9 dual-core

1024X600

[MTCB Android Head Units Q&A] typos1:
You cannot back up unless you have root, you cannot get root unless you install a pre rooted ROM. You do not need to backup as original files are on the fileserver as I said before, so you CAN turn back to what you had.

KGL usually use the blue type apps, so use a KGL ROM or KGL apps on another ROM. Just try all 3 main types - KGL, KLD, and JY, if you cant find them, although there is only the blue type and the red type, so not hard to find, certainly no "luck" involved - I know EXACTLY the apps your talking about, no need for pictures. Pretty sure theres a KYD ROM there, too, if not JY is pretty much the same.

Status report :

OK, found the firmware (updateJY1024x600KK4.4.4.150415), armed myself with courage and flashed it.

All went well, It has the blue apps like I wanted BUT the FM Radio reception went from decent to not detecting a thing. The region is corectly selected, the tuner chipset is ok because I hear static and some muffled radio stations but nothing with good signal (auto detection of the programs does not stop for anything).

I'll try another firmware....

[MTCB Android Head Units Q&A] agentdr8:
If your sub is powered by its own amp, it's probably because the headunit doesn't shut down the amp power-on line (blue) immediately when you take the key out. It goes into the shutdown sequence but the internal amp is probably still powered and puts feedback on the output. I'd try wiring your amp to use the ACC wire as the turn-on signal so it goes off when you remove the key.
[MTCB Android Head Units Q&A] kwalsh24:
Hmmmmm okay ill try that and see what happens, thanks not sure why I didn't think of that before now.

Edit

That wont work either, as once I turn my key off the amp will turn off, which is an issue I have right now with my radio (that's not to happen) which I'm also trying to resolve.

SiriusXM and Toyota Tundra

I live in the US.

Has anybody been able to get these units to work with SiriusXM? Also, I have a 2007 Toyota Tundra and was wondering if anyone has installed a unit in their truck. I am looking at either KGL-7618G (Toyota) or KGL-7650G (Universal). However, with the 4.2.2 units I have not found any that offer an aux input that could be used for the SiriusXM. I have seen several 4.1.1 units that do include an aux input that could potentially be used for satellite radio.

I was wondering in my case, if I got a SiriusXM tuner along with the Vais SoundLinQ3 (SL3sat) -- which allows you to connect SiriusXM and use with OEM radio and translates the satellite feed and emulates it so that you can use with OEM or audio input (aux). It also allows you to use steering wheel controls to change channels, volume up/down, etc.w_ww.vaistech.com/site/sl3sat.php.

I really want to be able to get SiriusXm without using the Android app... which would work I guess, but I live in an area that has limited 4g and I would have to tether my phone to car unit and use wi-fi. Not sure how well this would work.

So two questions...

1) Anyone get satellite radio (SiriusXM) to work with these, or other (4.1.1), Android units?

2) Anyone install one in a Tundra (or compatible Toyota) and which model did you buy?

Thanks for any info...
[MTCB Android Head Units Q&A] agentdr8:
I doubt any of the units will work with that SoundLinQ, as that requires the headunit support a CD changer or specific SAT input. The HuiFei's don't have either of those.

Best you could achieve is a standalone XM receiver that has a line out via RCA, which you could then pipe into the aux input on the HuiFei. You'd have to control it separately though.
[MTCB Android Head Units Q&A] R4D3N:
On my unit, for e46, everything works: radio good, wifi good, steering wheel control ok, preouts ok, backup camera, aux in, etc.

1. But, I do have a problem.

I check the GPS Monitoring box, everything is ok, it mixes the sound between GPS and Music but after a restart it doesn't until I uncheck and check that box again.

Can anybody give me a resolution? How can I resolve it? Or can anybody help me create a task which automatically uncheck and check that box at startup? I believe it can be done in Tasker but I don't know how to do it.

2. How do I setup de screen mirroring so that I can play videos and show pictures from phone on the navi via wifi?
[MTCB Android Head Units Q&A] typos1:
There is a company selling uniuts like these in Germany that does a DAB/DAB+ box for them ( http://www.icar-tech.de/html/index.php ), but dont think they do satellite radio as we dont get that here in Europe.

I agree about not using 3G/4G cos of reception.

The next best solution would be an external tuner that modulates the satellite radio signal to FM so your radio can pick it up.

You can also get this sort of thing in Europe for DAB.

The sound quality is very good, because unlike a cheapy FM transmitter, it will be hard wired into your aerial socket, so there will be no interference - like a perfect FM signal, I have used one myself and the sound quality was excellent.

It will also likely use RDS to give station names and programme info onscreen, so you would use your radio app and be able to view Sirius station names/prog info etc.

You will have to control it by other means as agentdr8 says, though and if it was me, I d be looking for one that you could hide and operate entirely by remote control without having stupid extra boxes on the dash.

There are expensive ones for DAB here in Europe that are hidden and connect to the CAN Bus and allow you to use the controls on the wheel or even voice control ( www.Paser.it ) as well, cant say if you can get the same in the US for satellite radio though.

In the UK we also get radio channels through digital tv so in car DVB-T tuners can also pick up digital radio, so an ATS-C box might be an option if US digital tv also broadcasts digital radio as well, then you could have full control over everything on the unit and with the SWC if you get a box compatible with this unit.
