“Sometime next year, Garmin’s Nuvi GPS devices will gain the ability to communicate with your car through ESP. In this case, we’re not talking about psychic extra-sensory perception, but the EcoRoutes ESP module for Nuvi navigation devices. The ESP module is a small hideaway box that communicates with Nuvi units via Bluetooth. The ESP module is a hideaway box that connects to (and is powered by) your vehicle’s OBD-II diagnostics port. The device gathers information about your vehicle’s performance and relays that info via a Bluetooth data connection to your Garmin Nuvi GPS device atop your dashboard.”
