Lowrance 5200C Chartplotter/GPS Troubleshooting

dropout

 Once I turn the unit on it reads GPS Module Not Responding. I have been searching the internet and more than likely the attenna/puck is bad. There also may or not be a 3amp fuse to the attenna. Did Rinker intall this unit with the fuse? I have not been able to find it. Is the attenna wired to Accessory switch? Any help or recomendations? Thank you.
