ecoRoute HD is designed and tested to meet the OBD II specifications that are required on most 1996 and newer cars and light trucks sold in the U.S. In Europe, OBD II specifications are required on most petrol cars from 2001 and most light duty diesel vehicles from 2003. Extensions were granted to manufacturers of some vehicles.
However, because some vehicles are not totally compatible with OBD II, we created this short list of vehicles that may be incompatible with our ecoRoute HD accessory. Due to the large number of different vehicle models produced and mid-year manufacturer changes, this list may not be complete. If you purchase the ecoRoute HD accessory from a Garmin retailer, and you find it is incompatible with your vehicle, you may contact us at (800) 800-1020 within 7 days of purchase for a full refund.
