J:\.System\RemoteSW --> I have two .gcd files: 006B154600.GCD (1,029 kb) and 006B211200.GCD (79kb)

Which one do I have to open it with RGN.tool? There is no gupdate.gcd file in .system folder....


J:\.System\ExtData ---> I have 8 .bin files: 006-D4511-01 (to -08)
Which bin file do I have to load to RGN.tool?
Happy to you too!

All you need is gupdate.gcd in .System folder! The nuvi55_56_450.gcd is the same gupdate.gcd for you if you have version of 4.50 of SW in your device. Do not have it - it is not problem. Goto here:
- Forum
- GPS Navigation Systems Sections
- Garmin GPS System
- Garmin Receivers Firmwares

and download nuvi55_56_450.gcd from link in this post directly...
