If the RCAs are removed from the radio but the noise is still present, that likely means it's being radiated from the vehicle somewhere along the audio path.

I’m not sure. I’ve contacted JVC as the noise isn’t present with factory radio. Not sure what the next step is but I believe I’ve done all the troubleshooting I can.

I will need to check with the R&D tech that did Honda. He has been out all week, but will be back Tuesday.

This might be a weird coincidence, but under the Maestro settings there’s a scan tool mode. If I turn that on, the noise stops....what is the scan tool mode?

Okay. So scan tool mode randomly turns itself off.... so I did more playing around with the settings. The door alert is the one triggering the noise... is it just a bug in the software that might be able to be patched at a later time? Sorry for asking so many questions that probably have no answers.

What you can try is to untape the HO1 harness and separate the k line (wire running down to the OBD2) and the RCA signal wires away from each other by a couple inches. It sounds like noise is being radiated from the K line to the RCAs, so spacing them out should resolve the issue.
