@asd255 Any idea where I could get the firmware file for a 4500?

@Potterg @slackwaredragon Question for you. I have created a replacement SD card for my AVH-W4500 and all works except for the integration of my Maestro RR. I have programmed the Maestro RR with the correct serial number from my AVH-W4500 but no matter what I have tried the Maestro RR continues to state I have provided it with the wrong serial number.
