TROUBLESHOOTING TABLE

VOlkswagen aRteOn wIthOut aMPlIfIeR 2019-2023

PROBLEM

SOLUTION

Gauges do not work, radio shows OBD2 Error 1 or Error 2.

Ensure OBDII 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.

The light on the Maestro is blinking RED TWICE and the radio IS turning on.

Reset the RR.
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 flash. Verify the radio's serial number entered during the flash 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 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.

The light on the Maestro is flashing RED ONCE.

There is no firmware on the module; flash the RR module.

After radio install, the airbag indicator light is ON.

Ensure airbag indicator light is reconnected. Go to settings of the aftermarket radio, OEM setup, Vehicle Features, then select Clear Air Bag Indicator. Light will reset if there isn't a fault with the airbag system.

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 flash 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.
TECHNICAL ASSISTANCE Phone: 1-866-427-2999 Email: maestro.support@idatalink.com
IMPORTANT: To ensure proper operation, the aftermarket radio needs to have the latest firmware from the manufacturer. Please visit the radio manufacturer's website and look for any updates pertaining to your radio.

INSTALLATION INSTRUCTIONS P1/2

DASH DISASSEMBLY
1. Using a panel tool, carefully pry outward on trim panel and vents around radio. (Fig. 1.1)
2. Disconnect the harnesses going to hazard and airbag indicator (do not cycle key with this unplugged).
3. Insert the four (4) supplied radio keys into the slots at the top and bottom of the factory radio with the tapered sides facing inward, pull outward to remove the radio from the dash. (Fig. 1.2) Disconnect all harness and remove.
4. (8 inch radio) Open glovebox and locate the factory CD player. Using 2 of the supplied removal tools, remove the CD player in the same fashion the radio was removed. (Fig. 1.3) Disconnect main wire harness and all antenna connections.
5. To make room for the aftermarket radio, trim subdash and dash cavity as necessary. (Fig. 1.4)
USB HOUSING 6. Remove one (1) T20 Torx screw from the center console
side panel, and release the clips to remove. (Fig. 1.5)
7. Using a pick tool release the clips at the top and bottom to release the USB, remove USB and disconnect the harness. (Fig. 1.6)
Determine which USB mounting option you will be using, depending on the year,model and trim the factory USB housing may differ. On vehicles that have removable USB ports, the factory housing may be reused by swapping to the included USB port. On vehicles where the USB cannot be removed, use the supplied USB housing.
Note: some vehicles may not support either method, requiring a new USB port for Apple Carplay/Android Auto to function.
If equipped with Start/Stop system 8. Using a small panel tool, remove the trim panel located at
the base of the shifter. (Fig. 1.7)
Pull upward on the shift boot. Reach under start/stop button assembly on driver side and pull upward to release it from console. (Fig. 1.8)
