I have the Z130bt for 3 weeks now and I believe the previous reviewer is overly harsh. On the Con side, I only agree with him on the preset station. I have no problem with the rest of the issues he pointed out (I have experience no freeze, no blank screen, quick bootup time,sensitive screen). On the GPS side, I admit that my handheld garmin is a better GPS but that is common for most car GPS. Maybe Kenwood with Garmin is a better GPS but users have other complaints on those units including slowness and freeze-up.
