Rear-View Mirror with GPS (PH-438)

Previously named the PH-438, the PHOPS is a GPS system that is mounted in place of your conventional rear-view mirror, and has a rear-facing cam input. With Navigon Mobile Navigator 6.5 inside, it's got "reality view", a 4.3-inch touchscreen, integrated speakers and Bluetooth and takes SD cards. It's actually got two inputs for rear-view cameras, which may be good news for the parking-skill-challenged. It sounds like a neat solution, but I'm a little unconvinced that mounting a GPS high up there on the windscreen isn't actually going to distract you from looking in the rear-view mirror_ after all, we know how distracting GPS can be.
