Well Larry,
I just put almost that on an owners new boat.

It's all BT and solarpowered (except the depth sounder needs a battery).

Not quite. They do not use BT, that would use too much energy. Tacktick
developed their own very low power radio and protocol for this. It's a shame
they still need a wire to your computer. We made a customized BT multiplexer
for them, but when the prototypes were ready, they bailed out....
