We first reported on Garmin ecoRoute hd back in November, when it was called ecoRoute ESP. Basically, this tool allows you to use your nuvi to monitor onboard vehicle diagnostics and performance data via a wireless connection with the car’s standardized onboard diagnostics port (OBD II). ecoRoute hd will be compatible with many current and future nüvi models, including the nuvi 1260, 1370, 1390, 1490 and 1690. This is a paid app (MSRP of $149.99), unlike the free, but more basic, ecoRoute feature included in many recent nuvis. It is expected to be available in March.
