I have a PhatNoise in a 2001 Passat. It has been working fine for about 8 months. Recently, though, it dies every few days. When it "dies", the head unit reports "NO CD", and both the red and green lights are illuminated on the PhatNoise unit (steady on, no flickering). I have tried ejecting the cartridge, cycling head unit power, etc. to get it to reboot, but that does not work. If I disconnect the cable where it attaches to the car wiring loom, though, it restarts 80% of the time. It will work for a day or two again, before I need to repeat.
I just read a post about pins in the cables not being fully seated, so I will check that out when I get home this weekend.
Any other suggestions?
