Transform any Apple device that uses the new Lightning adapter into a fully fledged GPS unit with the Bad Elf GPS ($129). A simple plug and play device, the Bad Elf GPS adds GPS and GLONASS location support, with a high performance 66-channel WAAS that includes latitude, longitude, altitude, speed, GPS track and voice guided turn-by-turn directions. It’s accurate to 9 feet, it works up to 60,000 feet and 1,000 mph, it uses satellite lock without cell without cell tower assistance, and it notes a hot start time in as little as 2 seconds. And, thanks to a pass through charging cable, you can even charge your iPhone/iPod/iPad while it’s in use. If you’re currently considering a separate GPS unit in addition to your iPhone, the Bad Elf GPS is a great, cost effective way to avoid having to carry around any extra hardware.
