connector is securely attached to the OBD2 connector of the vehicle.
If you hardwired connections at the OBDII, check connections at the OBDII connector. Make sure the RED/BROWN wire is on PIN 6 and the YELLOW/
BROWN wire is connected to PIN 14 of the OBDII connector. Do not use T-Taps. Soldering or military splicing methods are recommended. If anything else is connected to the OBD2 or CAN wires of vehicle (programmer, throttle controller, insurance tracker, etc.) try unplugging it to see if gauges work. If gauges work without it installed, call tech support for options. Reset the RR.
The light on the Maestro is blinking RED TWICE and the radio IS turning ON.| Ensure the 4-pin data cable is connected between the radio and the RR, and that it is plugged into the black port on the Maestro RR. The red and blue ports on the RR should be empty.
Make sure the correct radio model and serial number were entered during the fl ash. Verify the radio’s serial number entered during the fl ash matches what is listed on the radio screen. This can be found in the settings of the radio, listed as Device Id, Device Number, or Serial Number.
The light on the Maestro is blinking RED TWICE but the radio is NOT turning
on.| If installing a modular radio and it is not turning on, ensure the screen is secured and any trim pieces on the radio have been installed fully.  Not installing these fully will prevent radio from powering up and show a 2x red error.
