I had problems with my inverter/charger and replaced it. Somehow when completed my Garmans no longer provide engine information like fuel, temp etc. where is the fuse for the sensor located? I have a 2011 R 29. Thanks!
The inverter/charger wouldn't have anything to do with the Garmin and engine not communicating. If the engine is off, you won't have any data on the Garmin. Is your engine battery switch and ignition on? I would also check to make sure your voltage is above 12 volts.
