Try cleaning and slightly prying up the contact fingers on the radio plug and socket at Skooter mentioned. Also spray some contact cleaner or WD40 into the handlebar switch controls and give them a good manual workout. A check of the connectors from the switches to the radio would be a good idea too. If all else fails do a search on radio. Someone posted a repair shop that handled these.

Sounds very much like the connector on the back of the Panasonic radio. This part is notourious for this. You can pull the radio and after spraying the contactor with tuner cleaner use a small screw driver to lift the prongs. Will ususally work great for another 20K.

Good chance, that's a perennial problem with that radio. Do a search in the box above on 'radio' or 'radio connector' and you'll see quite a bit of discussion about it.
