Thread: Help! New firmware Update/Maps No longer readable

Still no Luck, I tried putting the old map back, but it can't read it.

On power-up it displays "Can't Unlock Maps"
Then "no detailed maps found that support routing, nuvi cannot be used without them"

When I go to about, I see the basemap, but not the main map.

I unlocked the maps using fast unlocker 2 and then the img file with gimgunlock as per lollipop's post above and I see my gmapsup.img in the map directory

Here is my GPS data:

Boot BLK B0972-00 6.20
X-Loader B0972-00 6.20
System B0972-00 6.20
Basemap F0057-01 5.01
Suppmap Erased
Suppmap1 ?????-?? 0.00 Western Alaska, Eastern... D523CDE2
JCV D3153-13 2.00
Splash D1340-50 2.00

So it looks like its treating the main mal as suppmap1, but not reading it correctly.

I loaded my original gmapprom.img and its not reading that either.

I downloaded a full gmap image and put that on the SD card and it appears to be working with the image, but I still get the can't unlock maps message
