My new 2010 RX 350 started off great. This good feeling lasted about 2 months until my first technical problem. Since the new Navi/radio system is so intricate and connected to everything, I've had problems with the climate controls, Navitraffic, XM Satellite radio and HUD display. I'm in shock. I thought Lexus quality stood for more. Well, my car has been back to the dealer 4 times, each visit averaging 3 days. Every time, the same story, we need to research this, we are unfamiliar with the new systems. I think I should have waited until they had gotten the bugs out. How frustrating my new car experience has been. Be forewarned.
I'll get back to you... once it' working right.
Take care of the bugs in the Navi/climate/radio controls.
