I have an XPR4550 that I converted from dash mount to remote mount. The radio worked fine in dash mount configuration with no issues. I have not changed any programming other than adding a few channels.

Now that it is a remote, I can only read/write through the GCAI port on the brick and I can't get any of my three microphones to work via the remote head. I thought there was a control head issue, so I swapped control heads with another radio, and same issue. Everything works except the microphone ports on the control head.

Before I invest too much more time/money in this, is there something obvious I am missing? Am I forced to use the mic extension cable with the remote kit?
