Anyone with the early Chieftain radios have a problem with it randomly switching from USB-BT-Radio-Off and not necessarily in that order. Mine will also sometimes switch off for 10-15 minutes and sometimes only for a second or 2. Drives me batshit crazy. Seems to be getting worse. And of course it doesn't do it all the time so I'm reluctant to take in to dealer cause I'm sure it will behave perfectly. Not sure what the connections look like under fairing, so is it possible one is coming loose?
