Considering how cheap and ubiquitous GPS devices have gotten, I'm not surprised that they're now the most commonly stolen item from vehicles. That's why Maplock caught my eye: it hooks onto your GPS and tethers it to your steering wheel.
The simple, but clever anti-theft idea comes from Australian-based Who-Rae, and recently won Popular Mechanic's Editor's Choice award at the SEMA car show. No word yet on pricing or availability, but if you've ever been the victim of a smash and grab, it could be one to keep an eye out for. [Maplock and Popular Mechanics via CNET]
