Seems the 10'-11' have a different system from the older ones? Can you purchase a DVD or you have to goto Lexus/

MX73

You have to go to the dealer. Beware of ones sold on eBay. Copied disk do not play nicely.

Yeah, I looked, it is like 200 bucks too.
I played with the nav before and not that thrilled with it. Time estimates are way off. It does not know the speed limits for each road. I'm not in real estate or delivery so what I have is probably more than enough.

It's ancient technology. It's not like the newer nav system in the current Lexus. It's not going to have the latest and greatest tech like the speed limit. I personally use my phone even if the car has navigation.
