Lowrance HDS 7 Gen 2 Touch Install in Lund Rebel XL Sport 1625

When I was going to install this unit in my boat I did a search for tips on how to do it on KZbin and found not much there. A few videos of Pros or shops installing multi unit "systems" on Pro Sponsored boats worth as much as houses used to be. So I thought I would make my own so someone else might be able to use it and have the confidence to do it themselves instead of paying a lot to some Marine shop. It is REALLY not very complicated. I also installed the Structure Scan transducer and purchased a Navionics Hotmaps Premium Card Canada for it.
