INSTALLATION INSTRUCTIONS P3/3
MAKE CONNECTIONS (REFER TO WIRING DIAGRAM)
1. If using head unit adapter (sold separately), connect HRRCHA1 harness to adapter and skip to step 2.
Locate the aftermarket radio's main harness.
Cut and remove the black 20 pin connector from the CHA1 T-harness and connect the wires, shown in the wiring diagram, from aftermarket radio main harness to the CHA1 T-harness and match the wire functions.
Note: only connect purple/white wire to radio reverse input or module damage will occur.
2. Determine if the vehicle has a factory amplifier. Look for badges on the radio, door panels and dash that indicate the presence of an amplifier (ex: Alpine).
If the vehicle DOES NOT have a factory amplifier: Plug the female BLACK connector to the male BLACK connector of your CHA1 T-harness. Plug the female WHITE connector to the male WHITE connector of your CHA1 T-harness.
If the vehicle DOES have a factory amplifier: Plug the female BLACK connector to the male WHITE connector of your CHA1 T-harness. Plug the female WHITE connector to the male BLACK connector of your CHA1 T-harness.
· Connect the CHA1 T-harness to the radio factory harness. · Connect the supplied antenna adapter to the factory
antenna connection.
3. Plug the harnesses into the aftermarket radio.
Connect the backup cam cable into the aftermarket radio.
Connect the antenna adapter to the aftermarket radio.
Plug the 4-pin Data cable to the data port (Idatalink I/F port) of the aftermarket radio.
Insert the Audio cable into the iDatalink 3.5 mm audio jack of the aftermarket radio (if there is no iDatalink audio input, connect to AUX).

Note: On Pioneer radio, ensure that there is nothing plugged into the W/R port.
4. Connect all the harnesses to the Maestro RR module (see wiring diagram).
If using an Alpine radio and the vehicle is equipped with parking sensors, lane departure, or other safety systems but NOT factory amplified, the ACC-SP1 is required.
All other radio brands, ACC-SP1 is optional. Without it, the radio will mute when park assist is active. With it, the chime will play through the speaker and the radio will not mute unless settings are changed in the radio. If factory amplified, the amplifier generates the chimes and ACC-SP1 is not required.
Press the CHA1 T harness, Maestro, and antenna adapter into the dash cavity and secure in place with cable ties.
Press the aftermarket radio into the dash cavity and secure it with the four 7mm screws removed earlier.
Reinstall the dash panel making sure all the clips snap into place.

TROUBLESHOOTING TABLE

PROBLEM

SOLUTION

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

If diagram shows CAN connections at CAN junction block, ensure a factory 2-pin white plug was disconnected, inserted into the female 2-pin of the CHA1 extension and the male 2-pin of the extension was plugged back into the junction block. Reset the RR.

When making a phone call you cannot hear the callers but they can hear you. Make sure that the 4-pin black and white connectors in the harness are plugged in correctly as stated in step 2.

The radio stays ON or doesn't come ON at all. The light on the Maestro is not blinking.

Make sure the 2-pin connectors in the harness are connected as stated in step 2.

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

There is no firmware on the module. Flash the RR module using Weblink Desktop and log in. Do NOT use DEMO MODE.
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.

The light on the Maestro is blinking RED TWICE but the radio is NOT turning on.

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.
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 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 P3/3

MAKE CONNECTIONS (REFER TO WIRING DIAGRAM)
1. If using head unit adapter (sold separately), connect HRRCHA1 harness to adapter and skip to step 2.
Locate the aftermarket radio's main harness.
Cut and remove the black 20 pin connector from the CHA1 T-harness and connect the wires, shown in the wiring diagram, from aftermarket radio main harness to the CHA1 T-harness and match the wire functions.
Note: only connect purple/white wire to radio reverse input or module damage will occur.
2. Determine if the vehicle has a factory amplifier. Look for badges on the radio, door panels and dash that indicate the presence of an amplifier (ex: Alpine).
If the vehicle DOES NOT have a factory amplifier: Plug the female BLACK connector to the male BLACK connector of your CHA1 T-harness. Plug the female WHITE connector to the male WHITE connector of your CHA1 T-harness.
If the vehicle DOES have a factory amplifier: Plug the female BLACK connector to the male WHITE connector of your CHA1 T-harness. Plug the female WHITE connector to the male BLACK connector of your CHA1 T-harness.
· Connect the CHA1 T-harness to the radio factory harness. · Connect the supplied antenna adapter to the factory
antenna connection.
3. Route B harness to the CAN junction located under the glove box. Disconnect one of the 2-pin connectors and plug it into the female B harness plug. Connect the male 2-pin from B harness to the CAN junction block. Connect B harness to main T-harness.
Note: this connection is only required for 2018+ models.

4. Plug the harnesses into the aftermarket radio.

Connect the backup cam cable into the aftermarket radio.

Connect the antenna adapter to the aftermarket radio.
