All the new files associated to new map:
1) mapset (CNNTNAm 2014.20==>gmapsupp.img or gmapprom.img)
2) gmap3d.img of this mapset
3) DxxxxxA.JCV of this mapset.
4) no other files for this mapset

Bye,bye

Hi Roger....

I am good to go since I have a gmap3d.img, D1279190A.JCV, and the "unlocked" gmapprom.img for CNNANT2014.20.

I should just have to copy and replace those files on the 765 and all should be OK.

I went ahead and deleted the old map on the 765 (which I had previously named gmapsupp.img) along with deleting the old gmap3d, tmz, jvc, and all the old unlock files.

I then copied the new 2014.20 files. I went ahead and named the 2014.20 map "gmapsupp.img" as that is what the old map was named. Note that I sort of recall I had deleted the original gmapprom.img and used gmapsupp as the map name several updates ago. I can't remember why I did that.

But when I booted the 765 up, I did get a message "Can't Unlock Maps". When I hit the "OK" button the unit booted up ok and when I check the installed maps in did show 2014.20 and the screen appeared top display the map OK. I tried re-booting a cpouple more times, and once again I got the "Can't Unlock Maps" message and hit OK and the map displayed properly.

So why am I getting that message and how can I get rid of it ?

There are no Unlock files on the unit and the only map on it is "Unlocked" so why does it say "Can't Unlock Maps" ?

Ya... that's what I used to unlock the img. The maps DOES show up and is unlocked.... but for some reason the unit says it Can't unlock maps.... but there are no "locked" maps to "unlock".

Have you also unlocked the GMAP3D.IMG ? That is also a locked file.

2014.2 works ok on my 765 & 755
