Re: Radio intermittently uses only one speaker
This may be useful, or not.
Remove all assoiated devices that you have in the AUX and unplug and other devices that may be connected to the USB. See if the issue is still ongoing. If it is gone reconnect each device one at a time to figure out which device is causing the problem.
I had a similiar issue the first day of ownership and it was a bad pairing with my Samsung Epic that was causing the issue.
