I have an older 2730 which most cetainly does not have GMA aware firmware. I generated a key with JM I used patched MapSource to send the map (CNNA2011.40) to the unit.

But the maps are still locked. I used the older Garmin "Unlock Wizard" to enter the key in Mapsource beore sending it.

So do I still need to use the Fast Image Unlocker to masage the IMG file ?

I don't recall having to do this with the last map (2011.3) on the 2730.

Or did I miss something else ?
