I have my dad's nuvi 255W and he's told me that all of a sudden it won't go past the Garmin logo splash screen. Logo appears, and within a few seconds, it power cycles. This was not after any kind of update. Simply worked one day, then two days later, nada.
I've tried pre-boot, but no joy. My computer "sees" the connection, as it gives me the device connected sound, but then about four seconds later, the disconnect sound is heard, and the nuvi power cycles again. I'm not sure what FW version is installed, but knowing my dad, it was the latest at the time. Any help would be greatly appreciated.
Quick side note: He's a retires Maj Gen from the USAF, and the implementation of the GPS service was one of his projects. Kinda cool, I thought...
Thanks in advance,
