I've been having a similar problem with my original radio. I put it in a new car a couple of months ago. Everything went okay with the install except that I could only get 2 stations (sometimes) and then only because I already had them stored. Reading through the FAQ I realised that this might be because I hadn't attached the remote line (because the way the car is wired it has a permanent power - something I need to sort out). Over the weekend I attached the remote line properly expecting huge improvements. It is better than it was as I can actually find other stations on a scan but even though I get a good signal the sound quality is nowhere as good as it used to be. On 3 bars I get drop-outs and it is very crackly. Could this be the same thing?
