I just bought an '05 used and have a small intermittent problem I hope someone can help me with. I'll try to explain as best I can what I've tried. When I key the mic to talk on the CB some times I get a squeal through the intercom. Mind you this doesn't happen every time I key the mic. I've tried turning off the Beep and Roger Beep and no help. The only way to keep it from doing it is to turn off the Intercom. When it does do it it's almost like a diode discharging as when you hold the mic keyed and it quits squealing at the same length of time every time. We're having some problems with our dealer right now, so I really don't want to take it to them if at all possible, so any help would be appreciated.
