The GPS Window Name is used to embed your external GPS application. So far I have tested it with the following.
App - Window Name
iGuidance - iGuidance
Street Atlas 2004 - DeLorme Street Atlas USA%trade 2004 - Map File 1
Destinator 3 - Destinator 3 - [Dest3.1]
I also tested Routis and it worked, but I don't recall what window name I used... The "%trade" represents a trademark symbol. This was neccesary to embed Street Atlas. I don't have a copy of the ones you are trying, but it should work with whatever the full title for the application is. Not sure about the error after setup will look into it....
