[MTCB Android Head Units Q&A] wokro:
Hi All,

I invested a lot of time in trying to get a stable Headunit, doing for me what I purchased it for: having a car Radio with Navigation and Music Player. Additional some apps like email, Web and etc.

My summary so far is not satisfying yet:

I went thru all the versions on my KLD: 4.2.2, 4.4.2 and 4.4.4 and all the time I got improvement to the problems I faced before but open a bunch of new issues every time.

e.g. the Radioapp was quite poor in 4.2.2, no good reception, loosing station memory, AF working but not as it should, it simply changed to the next available frequency but did not jump to the alternative Frequency of the selected station. The same in 4.4.2 but I think I recognized it's working now in 4.4.4. PTY names were senseless (e.g. "Phone In") in 4.2.2 and 4.4.4 don't remember 4.4.2 either not displayed or correct.

Launcher improved from 4.2.2 up to 4.4.4 but the weather is only displaying sites I've defined, the gps location based weather is not working for me.

Navigation: iGO worked for me in 4.2.2. in 4.4.x it is operative but flickers all the time, I tried a lot of things, (max_memory entries , installing the latest KitKat iGo version, etc.) nothing changed it. TOMTOM is working on all versions (personally I don't like it, so it's not my preferred solution) Sygic is nice but it's most often come up only with this nice white/red logo screen and stops. (if someone have similar issues with iGO I would appreciate to get some hint's how to solve the problem)

From 4.4.4 I ran into the problems that es file manger and some other apps suddenly stop, as described a lot of times above.

When using a USB hub with a 3G Dongle my GPS receiver stopped "receiving" for days. I think I solved this one by removing the HUB.

iPOD app with iPhone 5S is sometimes working sometimes not. I Have to reconnect it several times then it may show up the content and the iPOD can be controlled via the HU tochscreen (start playing music on the iPhone itself is working all the time) Had this in all Android version JB and KK.

MTCMusicplayer is nice but lacks from not having a database (need a long time to reed 6k Songs from my SD card). It also has no playlist support, search and Album Coverfunction. So for a big Mediathek it seems to me useless. I tried a lot other apps, some worked fine as Poweramp and MusixMatch, but the issue with these is that if you change from e.g. Poweramp to Radio or any other MTC Source the player does not stop and two sources are playing at the same time. (even with Xposed I did not manage to get it working).

And there are a few more things wich work half. All that results in a very negative WAF Factor (she gives a big pressure on me to have it working) and I spent too many hours of try and error sessions in the cold car.

Are you all fine with your HU or are you also in this, I would call it bit annoying situation that the unit seems to do a lot of good things but not doing it in the way you would expect.

Now I'm looking for a working configuration which could be:

using the Apps from 4.4.4 (Launcher, Radio, Musicplayer)- as they are the most advanced - on a Android 4.4.2 image which was for me the most stable. What do you think, will this be possible or will i ran into new problems?

Another question: is there a untouched factory image of the 4.4.4 Kitkat on 800x480?

thanks in advance and br Wolfgang

P/S.: sorry if the above list is boring or describing already discussed issues, but I thought to summarize the situation we or a few of us are in. Maybe someone can give me some advices how to improve

by the way, my unit is a KLD version
