We bought a fully loaded 09 RX 350 FWD with the Mark Levinson sound system and navigation/bluetooth system. The biggest disappointment has been these integrated system. Most of the buttons on the touchscreen are greyed out while moving, so that no destination or telephone no. can be entered using the screen. Not even by the passenger - who could safely interact with the system. The voice activated system is awful, taking forever to navigate simple prompts. Similarly, while moving, the radio will not display text info about the playing song using the full screen. You can, however, watch the info slowly scroll by five letters at a time on the little radio screen (risking life and limb).
Fit and finish is quite nice, performance seems quite good for an SUV.
Navigation and telephone control while moving needlessly and excessively restrictive. Voice control system an absurd joke.
