Unfortunatly all linux GPS solutions I have found out there (including GPS Drive) all use images of maps from a variety of online sources. These cannot do guiildance or route planning.Originally Posted by mst
Vector based maps are required to do navigation and route planning. This is what almost all windows GPS navigation applications use. I don't know why no one has stepped up, designed and wrote a linux GPS application that can use commercial available vector based maps such as the Nav-Tech brand or similar. Then all one would have to do is purchase the correct GPS map database CD or DVD to use with it.
