I recently bought a new Hummingbird Helix5 unit. It is mounted on the front deck with a trolling motor transducer. Everytime I raise the trolling motor out of the water the unit powers off and you have to power it back up when you lower the trolling motor. Also, is there a way to fix the screen where it stays in the down image mode all the time. I went to Cabelas where I bought the unit and they were not much help. Any help would be appreciated. Thanks
