I want to use a FM transmitter in my car. I can easily press the M for manual mode and select the right frequency. It seem to work but after a few seconds the car beeps 3 times and then "re-search" for available stations and end up finding the closest radio station.

Anybody have any idea why it does this? I guess it's not the alarm thingy because it beeps every time I change the frequency manually. Could be the temperature thing (broken shows -40 all the time.) but why would it "re-search"??

I'm confused. Hopefully someone here could help. Thanks in advance!
