Hi there,
as I can't speak russian, I am sorry for writing in english in a russian forum.
I am reading this thread for a while (with google translation) and it seems that it is the most extensive (and interesting!) one in the Internet about the android car dvd players espacially the ones from cusp.
I ordered mine through alibaba this summer and I am using it everyday. The unit had initially many problems most of them were solved with firmware updates, others unfortunately are still there.
The problem solved were especially with the remote wheel Keys and 10K resistance. Besides this, there is a false cable indication for remote key1 and key2 with the original hyundai i30 cable (should be the same as kia ceed) .
What is really annoying in my case the jumping time! Sometimes the System time changes randomly from -/+1 to +/- 8 Hours even with automatic time(I think the system uses GPS for that). I am using the Firmware 19 July 13. Has anyone the same Problem and got a solution for this issue? I hope that is not related to MCU MAR 2013 that I got.
I am currently trying to fix the issue with clocksync. May be it works.
What is still not working is the custom setting for the Equilizer. But as I got an external amplifier with integrated DSP that is not a real big problem.
Other issue is the big difference in Volume between the Radio app and the Android Media. Playing Radio is louder than playing songs over the Android Media Stream used by players such as poweramp. The Radio App seems to be a special app that controls directly the sound chip and the Audio of the Radio. It does not use the standard android audio stream.
Another Problem is switching back from reverse Camera display. It redirects me to the Radio (if running in background) instead to the standard android menu that was active before putting in the reverse gear.
I replaced the standard NExt Launcher(too much bling bling

) with Smart Launcher which is simple, much faster and memory lightweight. Besides this I added a tasker script which checks the gps location(or fix location) calculates the sunrise/sunset times, compares it to system time and adjust automatically the display brightness from day to night mode. It works quit well. The only Problem is when the System time jumps the display brightness will also be adjusted!
Will be great if anyone got an Info about this time problem.
Thanks.
