Hello fellow Mopar enthusiasts, this is my very first post so here goes! I know a guy that fixes radios (Chrysler & GM mostly) and he cleaned the switch contacts on the navigator for my 86 LeBaron GTS. Well, it is 70 percent better, but it really still doesn't work. Is there any Huntsville people out there, or some electronics supplier to get new switches for repairing these units? Regards, Brian.
