All wiring connections should be made using GM approved wire repair techniques which include, but are not limited to, soldering and heat-shrinking all connections.*** 1
Radio Removal: Step 1: Remove trim panel from surround of radio. On Acadia or SUV with center console, remove lower trim panel around shifter. Then remove top panel around radio. On Silverado/Sierra or Truck, remove panel around radio. 2
GPS Antenna Installation: All Vehicles Step 1: Remove covers to reveal mounting bolts on A-Pillars. Remove bolts and then remove trim panels. Trim panels should be held in by clips. Start at top and pull off carefully. Remove both panels and disconnect tweeters if present. Step 2: Remove front most dash panel near windshield. Panel is held in by clips. Use a plastic trim tool to pry from the close side of the panel, lift, and the pull out. Light sensor will need to be disconnected before panel can be completely removed. Find receptacle for GPS antenna, and seat antenna firmly in receptacle. Route the antenna wire into the dash and into radio cavity. If necessary, use a snake for routing. 3
VSS/Camera Harness Installation Special Note: Certain vehicles such as the Acadia, may have the 16 pin brown plug already present behind the radio (unused). It may be taped to the radio harness. If this plug is present, you will not need to run a wire for the vehicle speed sensor. Camera Note: If camera is present in rear-view mirror, it will not automatically re-locate to the navigation display. If you wish to relocate the camera from the rear-view mirror to your newly installed navigation radio, contact us to order GMMBH-SPLT-P (if your vehicle has power rear sliding window) or GMMBH- CONV (if your vehicle does not have the power rear sliding window). A 6 RCA cable will connect the GMMBH harness to the included VSS harness RCA camera input. Step 1: Pin 5, Green wire, of Brown C4 connector goes to the VSS wire. This is a Green/White wire located in the BCM Junction behind the brake pedal. It is notated by a Black box cover. If Orange plug BCM-C4(X4) is present in the rear of the BCM Junction, remove plug, remove Red locking tab, and populate pin 3 with the Green wire and supplied GM pin. If orange plug is not present, find Green/White wire in the BCM harness, Pin H1, plug C2(X2). Once wire is verified, tap supplied green/white wire into vehicle Green/White wire using GM approved wire repair techniques. For Acadia, Traverse, & Enclave, see next page.

VSS/Camera Harness Installation ENCLAVE, TRAVERSE, AND ACADIA For these vehicles, you may need to go to the Electronic Brake Control Module (EBCM) under the hood to find the VSS wire. You will need to lengthen the VSS wire that goes to the radio. VSS wire will be a Green/White wire populated into pin 11 of the EBCM Connector. 5
Procedure #1 Voice Recognition Harness Installation (Part provided separately as not all customers use this feature) Special Note: Acadia, Vue, Enclave, Outlook and Traverse: These vehicles may not require this procedure. Check for functionality by testing voice recognition before performing Procedure #1. If voice recognition is not working, perform this procedure. In Acadia, Traverse, and Enclave, the VCIM is located in the driver side rear quarter panel. For these vehicles, you will need to extend the included harness. All other vehicles, the VCIM should be located under or behind the radio. Step 1: Locate VCIM/Onstar Module On most vehicles, the VCIM is a silver box, located just under or behind the radio. Step 2: Plug the Grey Connector (provided separately) into the J3 Plug of the VCIM. Step 3: Pin the wires from the grey plug into the main harness C1 at the back of the radio. Follow Procedure #1 on the wiring schematic for pin locations. J3 Pin 2 will go to C1 Pin 4. J3 Pin 4 will go to C1 Pin 5. See attached auxiliary harness wiring diagram. Note: The Voice button becomes the Bluetooth button, and the voice recognition for the radio commands becomes the Source Button. 6
Procedure #2 This procedure is used to deliver navigation audio prompts directly to the left front speakers. Not all vehicles will require this. It is recommended to test functionality of this before performing this procedure. Y91/Y92 Note: Do not perform this procedure if vehicle has Y91/Y92 Full Digital/Lux/Centerpoint Bose. If vehicle has Y91/Y92, see UQA with Y91/Y92 Digital Bose Amendment instructions below Step 1: Brown connector C4 at the radio, included in the kit, has 2 wires pre-pinned to pins 8 & 16. These wires connect to the wires already populated into pins 2 & 9, respectively, in connector C1 at the radio. See attached auxiliary harness wiring diagram. UQA with Y91/Y92 Digital Bose Amendment On full digital Bose systems, the wires for navigation audio prompts (from brown connector C4) may need to be run directly to the Bose amplifier. This is not required on all vehicles. Test this functionality before performing this procedure. On Trucks, amplifier is located in the center console below the cup holders. On SUVs, amplifier is located under the driver side instrument panel. Step 1: Connect Pin 8 of the Brown C4 plug to Pin 13 of X3 at the audio amplifier. Connect Pin 16 of the brown C4 plug to Pin 5 of X3 at the audio amplifier. Use supplied pins (GMWIRINGPINS) if wires are not present. Programming Note: Vehicles with Y91/Y92 will require programming for audio to work. (Disregard if you purchased your radio from www.oemautopartsco.com it has already been programmed to your VIN) If radio requires programming in 2012 Vehicle, you may need to use a 2011 VIN when programming. You may also need to manually enter the RPO codes corresponding to the vehicle. These codes can be found on the inside of the glove box. For assistance, contact www.navrepair.com. 7
