myDSL Extensions (deprecated) :: gps on dsl
wow, sounds like a pain in the arse for the odd road trip. think i'll give it a miss and take my chances with map24.com 
Before you dismiss the idea, have a look at the maps on the Xastir site at www.xastir.org
If KE4NT's pre-built .dsl files in the MyDSL repository can make maps like that, AND support any NMEA-speaking GPS, then I want to download it and take look!
