We can hope.
I was advised by a TomTom employee some months ago that VR was never meant to work with NA 720's in the first place and that future firmware releases may kill VR, even with those using the 'hack'. Hope this isn't what we're seeing.
All we need is one 720 NA user to respond here that he or she has Navcore 8.010 AND NA maps 7.10, 7.15 or 7.20 AND that VR still works. If that is the case, then there should be a way for all 720 users with that combo to get VR to work.
I hear what you are saying, DHN, but just yesterday (first time for me to see it) I watched a Garmin NUVI commercial, and they were exponding the virtues of their VR not only to create a route, but to find an Italian restaurant and this and that. Sure does seem like TT would take note and get their act together in regards to NA folks.
