Not sure how its taken when posting links to other sites, if its a no-no sorry, just trying to help the boarding community by passing this along. Hoping someone here has the skills needed to help this move along.

Its very simple and straight foward with the same theory through all models and manufactures.
For starters the boat cruise works on the same platform as the car cruise.It takes one or more signals and make choices to acheive a constant hold.
These signals are pulse like the tach pulse and the vss(vehicle speed sensor)much like the pulse from a paddle wheel or the pulse from a nordskog gps pulse generator.
Most aftermarket car cruise controls are variable to compensate for different models and can be adjusted for many applications so in theory if you connected the nordskog to a css100 audiovox and the tach it would hold true with the gps.Also css100 can be adjusted to react faster or slower allowing you to dial in your throttle response.
The reason people have been unsuccessful with the car stuff is because of the safety features built into the cruise.For instance its set to not ingage before thirty miles per hour and can be over come by raising the pulse count on the module.Also it has a ground loop safety on the brake light wire that has to be grounded when engaged and positive to disengage which can be solved with a few relays.
In case you didn't know the nordskog pulse generator is a gps unit for offshore speed boats and streetrods.It simply takes the gps signal and turns it into a pulse that can be read.
The css100 is a audiovox cruise control.
For a grand total of $285 plus some wires.
