Thread: Using USB stick (a.k.a. stunt-double) to download map updates

HWID is 1947. I downloaded GCD from your second link and its content is same as what GE and MU downloaded during software update step as GUPDATE.GCD.
So, you are saying I can't do anything other than connecting actual nuvi first, and let it perform software update and create new XML file?

EDIT: Figured it out. I edited 2 places in XML file that contain old SW version 5.40, and replaced it with latest 7.50. GE is now able to proceed to update map step. Thanks for the hint.
