I've had problems with the OEM Becker stereo in my 964, 993, and now my 996tt. On several occasions, after starting the car, with the radio left in the "on" position at last shutdown, the radio/cd produces no output. You can tune to different stations, or select the CD function, but no sound. The only remedy is to shut the engine off. Activate the central locking with the key fob, then unlock with the key fob. This seems to restore output.

Now, the sound on the FM has gone weak. CD's play correctly, but the output level for FM is low and doesn't seem to have any richness in tone.

Any clues as to what could cause this? Head unit, or is there a separate amplifier?

For what a Becker unit costs, you'd think you get better reliability. I"ve failed 4 since 1993.

Thanks in advance for any insights.
