I just posted in "Audio and Electronics" but maybe it should have been here.. I can tell at a glance if I am 'Silent Running' !! Look for the Garmin nuvi post in the 'Electronics and Audio' section.
It's a newer Garmin nuvi, with the optional Garmin ecoRoute HD OBD II port reader. It is a bluetooth connection to the nuvi. If you get on their site you can look for 'compatible units' to the ecoRoute HD. It's not as versatile as a SGII or the Torque app and an OBD II reader. But I like the Big analog gauges, it keeps my phone free to stream music and be a phone and ,,,,,, It's a Garmin for navigating!! Dang, the built in Nav JBL system in my level IV is so lame...
Plug in the OBD II dongle and tuck it out of the way, plug in the Garmin GPS in the power outlet. I powers on and off seamlessly. And yes , there are lots of fuel usage pages, one with an accurate instantaneous MPG. Visit the site. You can really geek out on all the other functions. I use it mainly for these gauges. I'll switch over to "At the Pump" at fill ups. It gets more accurate with each fill up.
