I had my nuvi 265w had it hooked to the computer to charge, I accidentally formatted the unit. Now when I hook it to the computer it will charge but it won't see it as a drive, also the unit will reboot over and over, if I put a sd card in it will boot to the menu. Is there a way to get the software back on the unit using the sd card. If someone has the original info that was on the Unit can you please contact me Please..... HELP!!!
