PROBLEM SOLUTION
Gauges do not work, radio shows OBD2 Error 1 or Error 2. If anything 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.
CX-5 and Mazda3
No audio after installing new radio. Factory radio no longer has sound.
Check 7.5 amp “AUDIO 2” fuse located under the hood.
The light on the Maestro is fl ashing RED ONCE. There is no fi rmware on the module. Flash the RR module using Weblink
Desktop and log in. Do NOT use DEMO MODE.
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 as well.
Test red and yellow wires for DC voltage at radio using a multimeter. Contact
support if no voltage on red or yellow.
MAESTRO RR RESET PROCEDURE:
Turn the key to the OFF position, then disconnect all connectors from the module.
Press and hold the module’s programming button and connect all the connectors back to the module. Wait, the module’s LED will fl ash RED rapidly (this may
take up to 10 seconds).
Release the programming button. Wait, the LED will turn solid GREEN for 2 seconds to show the reset was successful.
