time for an audio upgrade i reckon!!, the gamma units are good, i started having a few probs with mine so put a sony cd/mp3 unit in which matches the red/blue illumination of the car

i think its the actuall switch, as it does 3 functions (radio on/off, and then used for volume and settings etc up/down), it would be quite costly to get fixed unless you remove it and strip it and try and remove/desolder the switch and try and get a replacement to refit. and as mp3 player etc are well down on price now you really have to think about wether its worth messin about or upgrade it......
