Thread: Garmin - Topo France v3 PRO PC release

my question is this, I always prefer to have a install for Mapsource or Basecamp, now a days more for Basecamp since Mapsource is becoming more and more death. When I have the map installed on my computer I can choose which portions of the map I want to send to my device. For example the map of France, I don't want the whole map of France on my device but just the parts that I need. When I install several maps in Basecamp, I can choose from each map which sections I want, and so which maps I have on my device. That's the reason why I use a install version of a map on my PC. When you use a IMAGE on a sd card, I suppose that you only have that full map on your sd card and on your device and you're not able to switch between maps.
Is this correct? That's why I don't see the point of using image files for maps...and always install versions...

Please correct me if I'm wrong,

thanks,

Sure, that's all basically correct. You cannot effectively just use part of an already compiled image. It is possible to make a simple preview map using GMAPTool to reverse-engineer an image, but it'll be a crippled installation, and there just never is a need to do that when a PC instal is available such as with this Topo.

As to switching maps, that's a no answer for most outdoor devices, other than switching SD cards each with a different map. You haven't said for sure that you have an outdoor, so if it's a car, truck or bike navigator it's possible to have several maps available without switching cards, but be aware that not all features of these modern topos are available on non-outdoor units. It's always best to say what unit you have so our answers can be specific.

If you're now comfortable using the PC instal go for it. As you said, because it's near enough dead just forget about using MapSource, and JetMouse is useless for the later programs so use the patched versions of BaseCamp and MapInstall to make your reduced size image and you'll be good to go. If you have any more queries, just check the tutorials first.
