I believe it's a gen 1 unit and was on the boat when I purchased it. Hds units at bow and tm locations. I installed an external puck at the tm and it now shows both.

First couple of trips to the lake the depth reading was working at the helm but temp never has. Now no temp or depth at helm. I've gone in and selected local on temp and still nothing. The unit at the helm has an lss1 transducer though it doesn't even show up when selecting transducers in the menu.

Ive gone through several old posts on this and tried the suggestions, short of cutting the yellow wire in half, but before doing that wanted to ask again on this since it's been 10 years for this to get sorted out. Ideas?
