Lexus put even more effort into making the 2007 RX 350 quieter than before with additional insulation and a new “acoustic glass windshield”. The silence, however, is only fleeting, as an optional Mark Levinson Premium Audio System stands ready to rock. A new fifth-gen nav system is also available on the RX 350 with twice the screen resolution as its predecessor.
