This what I use. I selected off with the ignition for the circuit that the GPS is connected to but with a 10 minute delay. This is usually enough time to complete a fuel stop without the GPS shutting down and fragmenting my track. With the Neutrino you can select any behavior you want by making the changes from the phone app. No need to mess with the wires once everything is connected.I'm planning on getting a nice Neutrino Black Box and thinking on using the ignition to put power to the Garmin.
