Has anyone been able to load the free GB250000 KMZ from the garmin website into basecamp I have not found any other application that will load it either, if you inspect the doc.kml file it refers to jpg images which are not in the archive eg images beginning with L1,L2,L3 only L7 images are present I have contacted Garmin support but they are being rather stubborn and refuse to look at it until they are given an error message to look at for some reason.

Better to ask this on the Garmin Custom Maps subforum on Garmin's forum where those that posted the map set might see your concern. 250k? Kinda a small scale for on the ground use.
In any case, It would help you if you posted a link to that mapset as it's not hosted here.
