Want more information on your car? Well, by next year, the Garmin Nuvi can access to diagnostic data from your car with an EcoRoutes ESP module. The module is small enough to put it somewhere behind the dashboard, and it will interact with the Nuvi via Bluetooth. The ESP module will connect and feed through the ODB-II port of the car. Once everything is installed, you can customize which gauges you want to display, and even set alerts for each one, allowing you to monitor real-time things like fuel consumption, and temperature of air, among other things.
