The Garmin ecoRoute HD is a bluetooth wireless dongle which plugs into your vehicles ODB port allowing you to monitor sensors such as intake air temperature, coolant temperature, throttle position and engine load, intake manifold pressure, battery and charging system information, mass airflow rate, timing advance and emissions — you can even check and clear engine trouble codes without visiting the car dealership.

The ecoRoute works with newer Garmin Nuvi GPS units that feature ecoRoute firmware, but since this is bluetooth… A) is it hackable? B) will an iPhone App be released from Garmin to pair with the device?

At $149 (retail) the Garmin ecoRoute HD is a great feature to add to your Garmin Nuvi GPS.  It’s available for pre-order now from Amazon.com.
