I started getting these symtoms that Curlykicker has described and like others in this thread ONLY in the car:

To summerize my bugs:

1)The screen in "Track: Info" mode is dimmer than the rest of the modes
2)Intermittant responding to the remote
3)Occasional (more and more often)"No hard disk found, Contact support" message
4)Frequent song hiccups and button freeze

At first I thought it was the headlight dimmer problem since only symptom 1) appeared but now I get all 4 symptoms. Has anyone confirmed if a new ide cable will "fix this only in car problem"?
