I wonder what parts you would need if I switched my current Wakeboard Pro to the
Stargazer Upgrade. The Stargazer Upgrade is $499 for my boat and supposedly includes a new Master Module & GPS Receiver. I would use my current display and wiring harness. I think you would then require a paddle wheel sensor, my old Master Module, a wiring harness, and display. I would consider selling you my Master Module for $250. What do you think?
