The LS 430 Ultra is the very best the car industry has to offer. Heated/cooled seats, perimeter parking sensors, laser-guided cruise control, integrated voice-activated phone - this has it all. My ONLY complaint is that Lexus disables 90% of the GPS functionality once you start moving. That is fine for safety (as the driver needs to pay attention to driving) but COMPLETELY ignores that there might be a passenger there who COULD use it. So instead, we pull over on the shoulder on the highway and risk death, to stop the car to put in the location - that we can't do otherwise because my Lexus is saving me from myself. This is going to be a GREAT lawsuit one day!
Fully integrated, voice activated telephone that uses speakers for sound and built-in Mic for hands free use while driving. Phone integrated w/GPS so can pick a point of interest on GPS and hit "dial" to make it call them.
Don't disable the GPS. Even use the passenger seat sensor to enable full GPS functionality.
