The things that you can check are the power supply to the unit and the connections on the back of the unit along with the fuse. Make sure that the unit is getting at least 10V DC to the plug on the power cord using a multimeter. If it is not, check the connections to the boats power supply and the battery to make sure that they are clean and tight. If all connections are good and you are getting at least 10V to the unit, you would need to contact Gramin at to schedule a return of the unit for repair.
