Garmin has a new spin on using your iPhone as an in-car GPS system with its HUD. Like the name implies, the HUD is a heads up display that projects navigation information onto your car's windshield. It gets the data from Garmin's StreetPilot or NAVIGON iPhone apps via Bluetooth and automatically adjusts its brightness so your directions are readable in sunlight or at night. Since HUD gets data in real time from your iPhone, it displays current traffic conditions, speed warnings, maps, and more. It includes its own power cable and a USB port so you can keep your iPhone charged up, and works as a hands-free phone system, too. This is especially cool in places like California where dashboard smartphone mounts are forbidden. HUD is priced at US$129.99 and will be available some time this summer.
