I was looking for general use cases that would apply to a good chunk of our users.
Personally I don't see much reason to have that feature in Basecamp as long as Mapsource is available.
You don't have to send the whole map in Basecamp either, just the parts you want. Right click your device, select Install Maps and follow the wizard :)
Really? omg..thanks...:o
Yup! I often use this feature not because I don't have enough memory, but because I just can't see the sense in loading hundreds of Mb of map tiles I will NEVER use. If you use routeable maps like CNNA, it makes searches faster, as well. My install of CNNA is only about 324 Mb.
