2007 3.2 AWD 29k miles. <p>I've been accumulating these questions for a while. I thought I would group them together to cut down on forum space:<p>1) When I start the car, put it in gear, and start to move, I hear lots of servo sounds coming from the front. I would imagine its normal, I'm just curious as to what it is and if other 3.2 owners hear it as well.<p>2) Is there any way to have the passenger mirror dip automatically in reverse? <p>3) Park Assist for most of a day, would scream steadily even with nothing behind the car. Not just beep but scream as soon as reverse was engaged. It stopped as soon as I got to the dealership. Has anyone experienced Park Assist hiccups? <p>4) NPR, Orbital, Beethoven- even on 0 bass, I hear rattles that vanish as soon as the sound is cut. It seems to be coming from the bottom of the driver's side B pillar. (no subwoofer) Anyone else?<p>5) My factory NAV is an '06 version that allows me to have full access to the system while moving- if I update to the new version with the 3D maps (how does that look, anyway?) will I forfeit the ability to set a destination while moving? <p>Thank you!
