Using the Garmin RGN_Tool v0.82 created by TurboCCC I made the RGN file from the Nuvi's original GUPDATE.GCD. It was 5 kb smaller, 8,700kb instead of 8,705kb. My Nuvi was a 205W having HWID 827 and software version 760. The update changed it to a Nuvi 465 having HWID 827 and software version 361.

Where do I get Updater.exe? I have the one from the previous post. It's version 2.8.0.0 and seems to point to the file 094301000370.rgn. When running with my rgn that has a different name it says "no files could be found...". I read you can drop the rgn file on updater to run. Is this the way to do it or do I need a different updater.exe?
