I bought a Unbranded Android Car Steoreo Head Unit and it went pretty good in the first place.
After i installed spotify and downloaded music, once the Wifi wasn't availiable anymore, spotify told me that the USB-Storage is no more there (but it is).
I thought a upgrade would solve this so i googled and found this Thread:
"AN-21 U" - Unbranded 6.2" 2 DIN Pure Android 4.1 Car Stereo Radio Head Unit
As my Radio says its also a AN-21 U i thought it will work.
This is my Radio by the way:
So after updating the MCU it lags a little bit and the volume-knob and the +/- knob is changed with each other and not responding proper either.
I also tried to update the System but activating this just boots up the device saying update start and update end at the same time, not taking any affects.
Software System Reset is not solving this, and im not abled to enter the boot menu (By pressing power on + vol up butten (i tried both knobs after MCU update)).
Do you have any idea for what i could do? I would really appreciate your help because im not able to solve it myself.
PS. Sorry if this is the wrong area
