In an interview a manager from TomTom said their adapter can be used by other nav software using all the features of the adapter. I do have the navigon navigator system on my iPhone. On youtube are videos showing that the TomTom adapter works with Navigon and co-pilot even on first Gen iPhone which don't have a GPS.
Here's a video showing Navigon running with TT adapter

In different forums I've read that TT will publish SDK on how to incorporate their adapter in other apps.
