GaugeFace is an app-and-dock combo that interfaces with your Harley's ECU (Engine Control Unit) to display the bike's speed, tachometer, engine temp., gear, and turn signal info on your iPhone or iPod touch. And the installation is almost as easy as setting your phone in a charging cradle. So, what do you think? Ready to turn your late-model motorcycle into an overpriced -- yet totally bad-ass -- iPod dock? Available for an MSRP of $250. See it in action after the break, or it the source link to order up one of these bad boys for yourself.
