I just replaced a 430W and installed a 650xi. I was able to use my existing wiring harness with the addition of the config module, fan wiring and a few additional power and ground wires/pins. The good news is that there was no smoke when I powered up and I have COM. Bad ws is that Section 5 of the install manual which deals with configuration is way over my head. I have a two screen non touch G3X with a GTX23ES remote transponder.
If you have a similar setup, would you have a checklist to follow when going through the configuration setup?
