Dear ben, I have a IPAQ 2210, Holux GPS receiver as CF card,Pocket MV and the open source (Graeme) New Zealand maps. I also have bought Brent maps, but can not get them to work. I created a subdirectory on my SD card with pocket MV in it and all the IMG files. Now it is a pain to get an image as all, as the Auckland maps do not seem to load. The South island ones do. Are there different layers and can I load map after map and load them on top of each other? Just can not get it to work, am I doing something wrong?
