hello,

 

I just bought a avic-f900bt. I like the system but i have 1 annoying problem.

 

When i want to play some mp3 files from my SD card i dont hear everything but when i turn on the radio or play a cd/dvd i do.

 

So only the playback from sd wont work. Its like there is a hidden mute button or something.

 

regards Kip
