I have access to a original SD card with the Bluechart G2 VEU053R map on. How can i copy and unlock it so it can be used on my GPSmap 520?

Copy it to your pc

And try this program
Garmin unlocker Alternative v5.31b - (07.07.2010)

And maybe you share it with as too....

Worked great!
I tried first with Garmin unlocker Alternative v5.23, but that did'nt work
Thanx for the link to new version.
Ill try to post a link to the unlocked img file later
