I get dealer supplied garmin units through my work and I just got a new garmin nuvi 1390T that has the capability of adding EcoRoute HD which is basically an adapter to run all tahoe diagnostics wirelessly to the nuvi unit, displays everything but my main reason for wanting to add it is it has a gas flow meter and live mpg along with code scanning and diagnostics. Just curious if anybody uses or even heard anything yet cause its an add on i have to pay for but sounds well worth it. hers a link
