Hm for me I chose the toyota dvd-avn for the moment even though it's expensive as heck because I just want some kind of compatibility for now with the car/steering wheel controls etc until something better/compatible comes out. As for the updates I asked my SA and they said to ask them for updates (my car is from umw itself), I'm not sure how you would get updates from other dealerships.
