Fried my nuvi 550?
Got my new gps up and running on battery power then decided the car charger should be a Powerlet so I could plug it into dash plug. Bad idea, or execution anyway... So, I snipped the car plug off, then wired my simple Powerlet plug. Of course, as soon as I plugged it in all went dark. Besides ruining the car charger, have I fried just the battery, or the whole unit? Thanks
