Hi Caty,
Usually I unlock with Garmin Kgen 1.5, but since Map ID >2000 I use Unlock Map Directory ver. 5.6.3.0 from *********.
All previous versions of CNEUNT I have unlocked with this tool and worked OK.
Now I think I have done something wrong during copy of .img file to device and since then I can't see the maps.
I'll try what you have suggest and came back with results.
Tx.
