Caty,

I want to flash back to 3790 from 3490. Since I can't download the file from your links (nuvi37xx_GCDFile__450.rgn), do you think I can just download nuvi37xx_GCDFile__480.gcd from Garmin website and save it as RGN using RGN_Tool ?
Or there is something special that you had to do for the RGN file ?

Thank you,
Andrew
