I helped a buddy mount a HB 998 on his boat with external GPS puck. It was fine on the previous boat. While using it last week on Joe Pool it would say No Gps position found & would not show contour lines. Used again on Arlington & contour lines worked but once again No Gps Position found. It does show the lake & he has the Lakemaster card in the right side slot. Should it be in left side or is this some other problem. GPS puck is mounted on back stern port side flat surface. We mounted it in the same place as I've seen many others mounted. Sonar,SI,& all other functions work great. Prolly something I did or didn't do right.
