This was originally designed by Robert L. Nuckolls III, but we've made a few changes in it and packaged it. The schematic pinout has been changed to simplify wiring, otherwise it is the same as Bob's original design—the relay switches 18 lines so that the VOR reciever and the GPS receiver can share a single CDI display—Cool! Similar to that $695.00 box somebody sells. Jeeeze...

Total to you (USA) $150.00 Shipping included.
