Update. I have changed the gps-head 2 times, the same problems appears every time. Then I got an error-alarm on the motor, think that is related to the deploy/stove-function. Finally Minn Kota Norway admitted they have major problems with the ulterra riptide model. The will not be selling this in Norway anymore. Im not kiddding, but all motors sold in Norway has stopped working and has been returned. I get new Terrova as substitute and the pay me back the price difference.
