Info from JaVaWa Device Manager:
Internal Storage- 1.5gb of 1.8gb used, gmapbmap.img, Topo24k_Northwest.img with 821 segments
Storage Disk- 5gb of 15gb used, D1529000A.img (Topo 24k North Central) with 784 segments, D1537010A.img (Topo24k Southwest) wtih 1812 segments.
Loaded Northwest topo 2 years ago (my home region), used extensively. Loaded North Central 1 year ago, used on vacation, switched back to Northwest topo upon return, no problem. Last month loaded Southwest topo, went on vacation to SW, no problems.
Now upon return to home I want to enable the Northwest topo map again, but it is no longer listed on my unit. JaVaWa and Basecamp see it, and I can manipulate it in Basecamp.
Why is it no longer listed on my device??
