Hi,
Just installed a new head unit (to go with my external HD MP3 player). Got on the motorway with music up loud (

), twenty mins into journey the music died! After much time spent verifying my head unit install I found that by jiggling the key the 12volt ignition switched line, that powers my head unit n mp3 player, becomes intermittent...on/off...mainly off

.
Anyone else suffered from this? Can it be fixed? Or should I take it to a garage for repair? Anyone know the cost of a new ignition key unit thingy??
Cheers
Ste
