Alright. I have been having this problem with my Rio for close to 6 months now. Initially I thought it was the IDE cable. Well, I just replaced it with a brand new one and the problem has persisted. Here's the problem: after I have used the unit for a short while in my car (say, 1/2 hour to an hour) the sound will suddenly start to distort and I will hear the audio cut out, try to come back, and what sounds like some form of digital distortion. I can pull the unit out and about 50% of the time after reinserting it it starts to work OK again for a short while until repeating. Everything else on the unit works fine...all the functions work, and there are no other signs of malfuntion. I've checked the solder points on the IDE header on the mainboard and they all look good and intact. I am really starting to miss using my beloved Rio...does anyone have any possible ideas what may be wrong or something I may have overlooked that I could try???

Thanks...
