Pros It turns your Droid into a Garmen GPS and a hands free vehicle mount. I love the optional dash mount. You can stick a round disk slightly larger than the suction cup on the mount wherever you want and it doesn't block any of your windshield.
Cons Nothing at all!
Summary This has also prevented me from needing to buy a hands free bluetooth device. I just plug a regular sized male to male headphone jack cable (mini-jack/ 3.5 mm) into my phone and into my AUX port on the car stereo. I can hear the person I'm talking to through my car speakers and they don't hear themselves echoing or anything. Freakin' SWEET!!!!
Cons Pricey at $29.95.
Summary The unit is extremely streamlined and doesn't interfere with vision at all. Holds the unit very securely and allows easy access.
Pros Easy to place mount on window, and easy to remove. Cell snaps in and is a solid. Easy to adjust angles.
Automaticly places phone in Navagation configuration when in window mount.
Cons No cons, replaced a TomTom
