Vehicle Diagnostics for iPhone

GL1 Vehicle Diagnostics for iPhone/iPad ($99.99, thinkgeek.com) Wondering how serious that “check engine” light might be? Get the GL1 Vehicle Diagnostics tool for iPhone— it works like your very own AutoZone representative. The GL1 plugs directly into your car engine’s On Board Diagnostics (OBD) data and shows you on your iPhone whether you’ll need to get it fixed ASAP, or wait for your mechanic to have a look.
