I'm just can't talk on the 9c with internal gps as I'm Q1 w/external. I do know gpsVP doesn't have a "Intermediate Driver" option which I think you need for internal gps. And again not sure if that GPSID thingy fixes that problem or not! If you can get gpsVP to see your internal gps chip then you would be set!
I did check out
Navizon and it does have a export function. So if you tried that and got it to see your internal you could export to say com 1 and set gpsVP to that also. Dunno... Try the Navizon lite free download!
Good option larsdennert!
