I have a 1995 Ultra Classic Tourglide with the same radio About a year ago it crapped out on me I hit a bump it would go off and then come back on when I hit another. I made lots of enquiries and was given many expensive quotes to install an aftermarket radio and was told by the Harley dealer that they did not repair them just got an exchange unit for a flat fee of $275 US which for me would be about $400 with shipping here in Canada which was way too much for me so I took the radio out and opened it up I had no idea what I expected to find but I did find a thingamajig when I touched it made the radio go on on off. I found an old school radio repairman and he completely overhauled it and resoldered the thigamajig for a total of $60 Canadian. I put it back in and it works perfectly. You might want to try this route and don't believe what dealers tell you they can be fixed !
