Is this how it is? Sorry, I just want to be sure I'm doing correctly. Do I need to remove GUPDATE.gcd for flashing 37xx firmware?
As the picture stated. 1st flash "nuvi37xx_GCDFile__450.rgn" then flash convert37x34 from SD card. From here, do I select 34xx or 37xx if asked?
Thank you very much Catmag for all your help and not giving up on me.
