I just purchased a used Navnet 1. I have the Screen , Dff1, 1kw Transducer, and a Bbwgps. When I received the items the Bbwgps's cord was cut and has no plug , I have a black cable though that plugs into a data port but is not the plug for the bbwgps because it has different color wires. I was wondering if there is a wiring diagram for this? Also if I bought the extension cable for it even though I really just need the plug I would guess cause it has enough wire, Would the color of the wires be the same in the extension cable as the bbwgps in case their is no wire code? I also have 1 more question. I don't know if I should ask it here or under the Navnet 1 section. I am going to update the Navnet 1 so it takes the FP C-map cards. I see that the DFF1(which is the older model I would think) has a rj45 to the data plug cable that came with it . Would this work for the update from pc to navnet direct? Is it a crossover cable or just straight ? Just wondering because it said running the Navnet straight to the PC would require it to be a crossover without a hub. Well this sums it up . Just need to figure these couple things out and I will be ready to fish ..
