Here's an interesting case. A new Motorola GPS unit, the MOTONAV GC550, has popped up in a filing to the FCC. It's got external photos, a full manual, all the relevant tests, the works -- and yet, somehow as of this writing, it seems to have never been mentioned anywhere on the internet, at least as far as Google, Bing, and Twitter are concerned. From what we can glean from the manual, the touchscreen device sports 3D mapping, voice commands, Bluetooth pairing with your phone for hands-free use, a microSD slot (presumably for updates like the previous models), Google local search, and information on weather, traffic, and flights. Not contained in these unearthed documents, unfortunately, is price or release date. Come on, Moto, don't keep us waiting long.
