Welcome to everybody.
I have M3 2005, 4 door, automatic.
I have issue with my in dash Eonon D5151.


This unit was installed a lest 6-8 month ago, and working perfect.
Last night, when I turn keys, lcd wont turn on, backlight too, looking like the unit is dead.
Today morning, when I turn keys, but not start the engine, I switch gear to reverse, my lcd pop up and show me view from my back up camera.
When I switch to drive position, radio start working normally.
But when I switch to parking position, and turn keys off, and again turn the key's and start engine, lcd is black, and unit wont start.
Do anybody have clue what is going on?


Already I disconnect neutral from car battery, check all fuses.
Fuse behind unit is good.
I push the reset button too.
I check also power on connector to the radio, is 11.2 volt.
Regards
Tom
