Hello, I have recently discovered the forum and the section dedicated to Android head units; before reading a couple of threads, I used to think my unit was pretty decent, but with some of the mods / apps provided here, it is almost flawless now. Thank you guys for your effort.
I have been using my Pumpkin unit for a while and only recently I installed XposedMTC and CarService, along with RK3066 (which I think was overkill) in an attempt to fix the only issue that was puzzling me: not all of my steering wheel controls would work; I got my NEXT/PREV to work and I can see the keycode in CarService app, but I have 3 other keys that don't seem to be picked up by the unit. These are the PHONE ACCEPT / REJECT buttons and the other once (which is the speech-to-command function).
I'm very new to both the Android head units and the modding that is behind it, so sorry if I don't make sense.
I am having trouble understanding if it is software related, or if the connection in this wires is going outside the CANBUS plug wiring; by this I mean that maybe these 3 keys are sending signals somewhere else? I say this because while upgrading from my stock unit, one of the plugs was left disconnected, as it had no socket to connect to in the new radio.
I'm not sure if this is the right place to ask, sorry for any inconvenience, but if someone went through this and managed to fix it, I'll be thrilled if you let me know how; the unit is from Pumpkin, and the car is a Mazda 3 from 2010.
Thanks in advance.
Hi guys,
I got a new HA2100 dual core head unit.
I'm new to all that staff but i have android phone for a long time so i know many of the terms.
I installed the latest Malaysk's rom and MCU version 2.83 and i have some question and problems.
The first and major one is that after the upgrade the wifi stops work, it not start, do this related to the MCU version? do i need to downgrade the version?
second question is about the built in 'Bluetooth' app, when i get a call it appears in the bottom of the screen and i can't do anything else with the head unit, for example return to the navigation app of search for something, at least i want it not hide my navigation app, There is something to do with it?
and last but not least, there is a music player app that can play music from storage and from bluetooth device (like my phone) in the same app or at least to display the song name from the bluetooth device?
Thanks,
It's really great community!
I have a MTCC-KLD6-V2.97 Android 5.1.1 800*480, with a december stock rom.
Since I've installed it, I always had a problem with the bluetooth: at the first start, if I do a search does not find any device and from my smartphone I can not find the unit.
After a completely shutdown (with car off) and restart, the bluetooth seem to work properly and i can connect my phone; the same thing happens after I went to the factory settings or when it boot with Android logo instead of the configured startup logo (It appears to be a fresh start after a unit reset, or similar): I have to turn off the car and wait for the complete switch-off time, otherwise I cannot have a Bluetooth connection with my phone.
The problem does't seem to be related to the Rom or MCU, I made several attempts, and the problem still persists.
I don't know if it can be linked, but when I tried a Malaysk 5.1.1 rom, I had to disable the MCT Service module, because otherwise I couldn't always connect my phone.
Someone has encountered a similar problem? How did solve it?
Have you checked that you have the correct BT module enable in factory settings ?
I think yes.
Let me explain: when I received the unit, in the factory setting was set on IVT_BT type.
I always had this problem, so one of the attempts that I made was to change the type of form, and I have tried all the available ones:
WQ_BC5
WQ_BC6
Parrot_FC6000T
IVT_BT
SD_BC5
WQ_BC6B
WQ_BC8
SD_BC8
In all cases, after the boot, in the Bluetooth settings does not appear the name of the unit and the pairing code.
If I try to manually configure name and passcode, if I go out on the settings it lose them. If I try to do a search, no device found.
The only module that seems to work is IVT_BT, but occasionally causes me the problem I described above.
The unit has always had 5.1.1 rom, what I thought of trying to do is use a 4.4.4 rom (maybe the new Malaysk), it could be a solution?
AFAIK, apart from the Parrot modules that have just started to appear, MTCB and C units always come with BC6 BT module. KK shouldnt make any difference really.
The only way to tell from certain is to remove the top, does it have a DVD/CD drive ?
Yes, I'll try to disassemble the unit and open the DVD to check the physical BT module.
But I don't understand, if I configuring in the factory settings the BC6 module will don't see the unit name and passcode and I cannot set it up in the bluetooth configuration... Also the MCU version don't make a difference?

Thats why I said have a look at the BT module, to establish exactly what one it is.
You could try MCU MTCC KLD9 v2.98 and see if that works better, its newer.
This is the BT module; unfortunately I cannot see good the face with the processor, I should completely disassemble the radio and today I had no time...
However, it seems that there is nothing written over that show the kind of bluetooth ...
I think I'll have to disassemble everything, find someone that sell me just the module and change it

Its quite easy to remove the DVD drive and/or the side of the unit, there should be writing on the bit of the BT module that faces the side of the unit.
Bluetooth Issues
I have a question with the BT on my unit. I have the external Mic connected and people complain that they can't hear me and they always hang up me. Music works fine but on phone call I have to switch my phone to Speaker. Would disconnecting the external Mic would improve the call quality. Do you suggest I get another external microphone? If you do can you please link me to a good one. Please see the picture for my unit's information.

Theres a specific thread about how to mod the mic in the hardware section.

No, i'm sorry. The touchscreen of my old unit it broken, so i've changed it with a most modern unit, with 2 GB ram and Nougat os.
Hello
I am having problem with controlling the steering wheel control to next/pervious the song.
The radio and the music of the rom is working fine but when using other apps like Spotify, YouTube playlist... Etc is not working I have to do it on screen. Is there anything I can do in settings?
Btw Iam using 4.4.4 malaysk rom rk3066.
Hello! Were you able to fix the problem? I have a similar issue with my car, when I go to Spotify and start playing a song, I can go to the prev/next track but as soon as I leave the app, I can no longer go to the prev/next track. I can do it from the notification but not from the steering wheel or the controls on the face of the headunit. Also, whenever I try to skip a song from any of the buttons, I also lose control of the volume. So, I'd love to know how you fixed it if you have fixed it.

Being an mtcb, since posted in mtcb forum, suggest time to buy a newer unit to update your old mtcb unit, such as a FYT based unit uis7862

I see. Upon further testing my problem seems to be android related. I can't skip songs if I don't have the app open on screen. Had this with one of my previous phones too and it fixed itself one day. We shall see.
I recently installed a Xtrons PQS90MTVL head unit in a skoda superb. I have a couple of questions on how to get it to work correctly when navigating.
1) It seems that you can set the navigation sounds to be a percentage of the radio volume but cannot set it to play at a given volume regardless. The problem is that the radio seems to be constantly on and there is no way to turn it off. The 'on/off' button simply mutes the radio - and the navigation sounds.
Often I am in an area where I cannot pick up a decent radio signal on the programme I want and just get static. In these situations I want to turn the radio off but still hear navigation sounds. I don't want to listen to loud static just so I can have the nav sounds play at a percentage of that static. Is there a way to turn the radio off but still get navigation sounds? (a workaround I have found is to play a media file instead of the radio and then pause playback. The nav sounds are then still a percentage of the - non existent - playback volume. However this should not be necessary)
2) It also seems that a Internet connection is needed for any navigation. even google maps won't do a search without it as it says I am offline. (is this true?)
I have bought the 4G wifi dongle but have a question about its use. Does the HU connect to the dongle, as far as data is concerned, via the USB socket that comes out of the back of the unit or is that socket simply powering the dongle and the HUI is actually connecting to it over wifi using the dongle as a hotspot? If so then I don't have to use the wired usb socket from the unit (which I suspect is underpowered) and can plug the dongle into an ordinary 2A USB socket that I have in the car, positioning the dongle near the roof for a better signal
Incidentally I did try using Android Auto with my phone using wired connection. That seems sort of OK but is not very reliable. Often when starting the car it hangs at the 'connected' screen, or even at the 'trying to connect' screen, although other times it seems OK
3) There is a small socket on the left hand side of the HU that looks like a slot for a small memory card or a sim card. It is labelled 'GPS'. What is that socket used for? it is not mentioned in the manual as far as I can see. - The manual is generally a bit hand waving though, excitedly telling you what you can do but not how to do it.
(I did try the xtrons forum but not only are the last posts there around January 2022 but there seems to be no way to register for it. Hence posting here)
Is it MTCx post system info including mcu version.
Mtcb is long retired

All I know is the model is Xtrons PQS90MTVL so maybe its MTVL (whatever that is) I'm afraid I don't know what mcu means so cannot offer any version for it. Its possible I have posted this in the wrong section and have rep[osted in 'Android Head-Units'. If that is the right place and this is the wrong place, please can you delete this post
