Haven't found a solution yet. Tried to check the cables but could not fint the amp ?!
Checked everywhere, except for the dashboard/centerconsole

Tried to disconnect the battery to see if that should help (mostly because the PDC doesn't work - didn't sort out any problems at all.

On the other hand i discovered that now the radio shows the radio name in the display, instead of just showing the frequenzy of the channel.

Seems more and more weird, dont really know what to do with it
