Nothing beats a RAM mount with a ProClip USA device-specific holder. The non-powered one is out for the TP2 and the powered one (which you'll want for use as GPS) will arrive shortly. You cane see pics of mine (with my Mogul) at
www.kevinsawatsky.com/voyager (scroll down). I also have a RAM Aqua Box (Medium size) which I use for wet riding conditions. It fits the TP2 perfectly, even with a little padding to protect the phone from scratches.
