I have had mine for some time now and this just started. It is a 7715. Been great, but lately, it will power itself off while driving, then turn back on and no longer have destination. There is a small LED on the top, either red yellow or green. My guess is either the 12v or whtever it uses, is going or the internal battery is shot. Gets to a low level, then sort of catches up. No obvious way to replace a battery. New one tome?
