I just got my CB 400 back and the firmware was found to be corrupted. James and crew were able to reload the firmware and it all checks out.
I have no idea how that happened, but my new CB 400 was acting weird with the mgps plugged in, so maybe it was that? James said to send that in too.
I wanted to make sure to close the circle in case anyone else has funny stuff with their CB 400!
Oh and it was all under warranty repair even though I acquired that CB 400 over a year ago! It was sitting unused in a box for my A-10! Thank you for the wonderful service Jeti!!
