INSTALLATION INSTRUCTIONS
STEP 1
• Unbox the aftermarket radio and locate its main harness.
• Connect the wires shown on the next page from
aftermarket radio main harness to the rHK2 T-harness and
match the wire functions.
• Connect the rHK2 T-harness and the RCA cables to the
rSPDIF1.
There are two switches on the rSPDIF that need to be set
properly: Bit Rate and Input Level:
• Bit Rate: Set switch to 48 kHz.
• Input Level: If the radio you are installing has a rca preout
voltage of 3 volts or less (Look in the radios owners manual
for this specification) set the Input Level to “Low”. If the
radio has a rca preout voltage of 4 volts or more then select
“High”.
Note: Isolate (tape) unused wires, if applicable.
STEP 2
• Remove the factory radio.
• Assemble the rHK2 T-harness as shown in wiring diagram
(If there is an OEM camera, connect the backup cam rca
cable to the rHK2 T-harness, as shown).
• Connect the factory radio harness to the rHK2 T-harness.
STEP 3
• Plug the male BLACK 2 pin connector of the rHK2
T-harness into the OBDII harness.
• Plug the OBDII connector into the OBDII of the vehicle,
located under the driver side dash.
STEP 4
• Plug the aftermarket radio harnesses into the aftermarket
radio.
• Connect the RCA cables in the front RCA outputs of the
radio.
• Plug the backup camera RCA into the aftermarket radio’s
backup camera input (if applicable).
• Plug the Data cable to the data 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.
STEP 5
• Connect all the harnesses to the Maestro RR2 module
then test your installation.

PROBLEM SOLUTION
Gauges do not work, radio shows OBD2 Error 1 or Error 2. Ensure OBDII connector is securely attached to the OBDII connector of the
vehicle.
If you hardwired connections at the OBDII, check connections at the OBDII
connector. Make sure the BROWN/RED wire is on PIN 6 and the BROWN/
YELLOW wire is connected to PIN 14 of the OBDII connector. Do not use
T-Taps. Soldering or military splicing methods are recommended.
Reset the RR.
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.
The audio from the aftermarket radio is way too loud and distorts the
speakers very quickly.
OR
Audio is quieter than the OEM radio.
First make sure the Input Level is set correctly on the rSPDIF (see Step 1 in
the Installation Instructions page).
Secondly, you can adjust the gain of the OEM amplifier by going into the radio
settings and go to OEM Setup/Vehicle Features/Vehicle Amplifier/Gain. The
level is 10% to 100% with 10% increments. If the audio is way too loud lower
the gain of the amplifier and if it's too soft raise the gain level.
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.
