So one morning the car didn't start and after it realised radio won't turn on and FM transmitter in the cigar lighter is dead. Starts fine after charging the battery but radio is still not working, as the FM transmitter. Wife used the car last and she couldn't say if radio worked then.
Fuses are fine (left side of dashboard, I think just these are relevant). Anything I could check myself or is the radio completelly dead? If so then how could it happen?

Assuming you mean strange problem, I'd be more concerned about the car not starting then a radio that won't turn on. What is the FM transmitter that you are referring to? If the radio won't turn on at all (no illuminated indicators) then either no 12V power, no ground connection, or a failed radio.

Hi,
Yes, strange problem.
It's been starting OK after I charged the battery. So I just assume what ever happened, drained it.
FM transmitter is a device that goes into the cigar lighter for power. It has bluetooth, USB and SD card connections, send music to FM frequency so it can play from car speakers. Easier than adding the functions directly to the stereo, at least for old models.
As far as I can see, stereo and cigar lighter are different fuses, both are OK. I really expected both or at least 1 to be blown. Checked all (left side of dashboard) because it seemed so strange. So fuses are OK but stereo and FM transmitter don't work. And they don't have any connections between them. Cigar lighter has 12V, I haven't yet connected any load to it.
