Radar stuff vexing

[phil23]

This is most probably a crazy notion however I have a radar scanner which I believe to be fatally faulty and a display which appears to be fully operational is it possible to use another brand scanner to my current display ie: Garman (or any other brand) to JRC scanner

In almost every case antennas and displays are proprietary. Troubleshooting is a challenge but once you've confirmed the failed component you'll be able to find a used part on line for almost anything.
