Hello All

Recent updates on Atlantic Routable Highway Basemap v3

Converted the basemap file gmapbmap.img to gmapbmap.rgn using makergn.exe tool as instructed by Neil on previous post.
Region 3 used for basemap.

Renamed the file 026001000611.rgn for Garmin GPSMAP 296
Renamed the file 040201000571.rgn for Garmin GPSMAP 396

Used updater.exe to upload each file to each GPS (same updater used to update firmware, thus the file rename) and...
SUCCESS: Now I have the ATLANTIC ROUTABLE HIGHWAY v3 on both GPS.
Now it's time to try that on my airplane, a 1969 Citabria !

Thanks Alfiogigio, Thanks Neil.
