I installed the new 2.0 firmware onto my F500BT. Now sometimes it will reset and the time will be reset to 3:00. I believe it only happens when I turn it on and off quickly. I imagine something is trying to load, and it gets cut off. I try to remember not to switch from battery to ignition too fast, but it is fairly annoying.

 

Is there some way I could reload the firmware? Or roll it back to the old version? I am running just the basic unit with no mods.
