Happy New Year to All!
I have a Nuvi 55LM.
HWID: 1697 | SWVS: 450 | MAP: Yes | GMA: Yes | MSV: Yes | GSV: Yes | File: nuvi55_56_450.gcd
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?
I am very confused with RGN.tool? Please help me.... Thanks.
