oh yes..thank you ..but doesn't help....i do have the tool..but here's the explanations:
Convert GCD to RGN
•File->Open and select your GCD file
•File->Save to RGN and select the RGN file name.
•Remove any previous GUPDATE.GCD file from your GPS before flashing
•Flash in pre-boot/service mode using updater.exe from Garmin
now where is the GDC fle ?? what does it mean?
select the rgn name ? what name ? arbitrary?
flash in preboot service mode..(how does one do that? see what I mean...incomplete and unclear explanations
