I follow step by step how to unbrick my nuvi 3790t but stuck on : 2. Format the unit using RMPrepUSB - cant find garmin nuvi drive and i cant continue ! I try to put my micro sd card on nuvi but nothing just not working for me . Any idea ??
Check to see if you can see the Nuvi in Disk Management (Computer Management Storage Disk Management)
If you can see it then create partition Fat32
SD Card must be formatted Fat32 not NTFS
Did something change after you flashed the Nuvi.
