I just read your post and downloaded IGmod and it works pretty well. I have a few issues but that could be because I downloaded the preview 4 version rather then the latest beta version. Which one are you running?
I have issues with the OSK being offset on the screen, my poi's don't seem to work and I had a problem trying to set a route. other then that it is working OK. I only had a chance to set it up and play with it for a very short time, so maybe I will resolve the other issues as I play more.
