Hey Folks,
I'm trying to flash my Maestro RR to connect to my Dodge & JVC KW-M750BT head unit. Problem is when I enter my serial number I keep getting the "incorrect serial number" message. Very frustrating, Any ideas??
Thanks in advance

Make sure your serial number matches this format: 123X4567

If it still does not accept it, send us a picture of the top of the radio (showing model and serial number) and we can ensure it's in our system. Send to:
