I also have red needles and have enjoyed watching the tides change as folks at one point were seeking white needled cars only.
It does seem that the red needle cars infotainment is more stable and potentially sound better (not sure if this second point was ever confirmed). If I ever do come across another TourX owner, one of the first questions I will ask is if I can listen to their white needled system for comparison. However, while I think the red needle dash looks better, I do think the white needle screen graphics look cleaner, split screen is cool, and flac compatibility is neat.
Back to your question....I'm pretty sure the answer to free map updates is a resounding "NO".
