have a 1198c si. my tracks from last year are no longer displaced. also the waypoints are no longer there. also froim this year my tracks and wayponits are not there say 2 weeks later. can anyone tell me whats going on. also running at high speed the screen goes black or fades out. i have a lund boat. all the wireing was done at the factory. i was able to run at high speed before and no fadeing out. over nite this happened. the transductor is level and looks ok. the picture of the under water strucker looks great.


thank u
