Thread: Garmin BlueChart g2 Vision VUS515L-Brownsville - Key Largo (10.50)+(11.50)

catymag, Hi. Update. Well, I copied your 11.5, merged it all in one file and then I think I got the unlocker to work, but when I put it in the 740S, it read the file, the system info says it's there, but then it says it can NOT unlock the map. So I can only assume the unlocker didn't work maybe? Any thoughts? I've only been at this for 5 hours! LOL

It is the Garmin GPSMAP 740s. The new 7" touch screen GPS/Sounder unit. Yes I did put the unlocker in the garmin file where the gmapsupp file is located. The unlocker brought up a black box and the correct file. I walked off to let it do it's thing and when I came back it had closed and back to the garmin directory. So I figured it unlocked it. True it went into the 740s, but it wasn't unlocked. Hummmmm
