A new accessory from Garmin, the ecoRoute ESP cable, connects to your car’s on-board diagnostic system (OBD-II) and links to Bluetooth-enabled Nuvi 1xxx series GPS units to provide a plethora of data on your car’s health in an easy-to-read, visual format.

What sets it apart is the eco-dashboard seen in the screenshot above.  Looks like a neat way for hypermilers — or hypermilers in training — to get visual feedback on their driving habits and improve their car’s fuel efficiency.

There are a lot of unknowns surrounding the device, but rumors indicate that the unit will cost $150 and should see a release by year’s end.
