STEP 1
• Remove the factory radio.
• Unplug 4 pin white speaker connector and connect RCA
adapter.
If using head unit adapter (sold separately), connect HHR-
TO2 harness to adapter and skip to step 2.
• Unbox the aftermarket radio and locate its main harness.
• Cut and remove the black 20 pin connector from the HHR-
TO2 T-harness and connect the wires, shown in the wiring
diagram, from aftermarket radio main harness to the HHR-
TO2 T-harness and match the wire functions.
Note: only connect purple/white wire to radio reverse input
or module damage will occur.
STEP 2
• If the vehicle is equipped with an OEM backup camera, a
16 pin and 24 pin adapter are provided to retain it. Identify
which harness your vehicle has and connect the adapter
to the vehicle and to the 8 pin connector on the HHR-TO2
T-harness.
STEP 3
• Connect the factory harness to the HHR-TO2 T-harness.
STEP 4
• Plug the male WHITE 2 pin connector of your HHR-TO2
T-harness into the OBDII harness.
• Plug the OBDII connector into the OBDII of the vehicle.
STEP 5
• Plug the harnesses into the aftermarket radio.
• Plug the backup camera RCA (if applicable).
• Plug the RCA cables into the aftermarket radio outputs.
• Plug the Data cable to the data port of the aftermarket
radio.
Note: on Pioneer radio, ensure that there is nothing plugged
into the W/R port.
Note: For Sony radios with OSD Controllable camera: When
the vehicle is equipped with the bird’s eye view camera
system, plug the camera into Camera 1 on the radio. This is
the only camera input that allows camera control through
the touchscreen.
STEP 6

TROUBLESHOOTING TABLE
PROBLEM SOLUTION
Gauges do not work, radio shows OBD2 Error 1 or Error 2. Ensure 2 pin black connector is plugged into the 2 pin black of the 28 pin
connector of the TO2 harness, not the OBD2.
Reset the RR.
Gauges work but are limited or data features are limited (turn signals, very
limited gauge functionality).
Ensure 2 pin black connector is plugged into the 2 pin black of the 28 pin
connector of the TO2 harness, not the OBD2, then reset the RR.
If still experiencing limited functionality, try connecting the black 2 pin from
the TO2 to the OBD2 2 pin black connector, then reset the RR.
TPMS display shows N/A or does not update tire pressures. Reset the RR. Drive the vehicle. If still not updating, contact tech support.
The radio is NOT turning ON and the light on the Maestro is blinking RED
TWICE.
If installing a floating screen type 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.
The radio is turning ON and the light on the Maestro is blinking RED TWICE. 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 flashing RED ONCE. There is no firmware on the module; flash the RR module.
Radio will not turn off. Vehicle has aftermarket remote start. Contact technical support for assistance.
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.
