After 5 years of use, for some unknown reason I've lost the gmapbmap.img file for my GPSMAP 66i. I've travelled around the world with my GPS unit, and have spent hundreds of $'s on ActiveTopo charts for every continent. The unit's settings are tweaked to exactly fit my needs.
Last month, I noticed that my gmapbmap file is missing, meaning it's difficult to find specific locations on my unit in advance of the unit being in the location. The ActiveTopo maps pick up only at a certain scale, and the base map is used for all levels above that. My unit has every other base file, including the gmaptz files, and all other necessary files.
I called Garmin support, and they said that the only way to replace the gmapbmap file is to send in the unit, and receive a refurbished one for about $200 (including shipping). Not sure what will happen to all my ActiveTopo charts, etc. I'd rather keep my unit, and somehow just replace the lost gmapbmap file. Is there any possible way to do this? I might not fully understand the technical reasons this may not be possible, but I'd like to try.
Thanks in advance!
