Look for badges on the radio, door panels, and dash that indicate that the vehicle has Bose.  \nIf the vehicle DOES NOT have a factory ampliﬁer: complete the installation as shown in the wiring diagram without an ampliﬁer.  \nIf the vehicle DOES have a factory ampliﬁer:  \ncomplete the installation as shown in the wiring diagram with an ampliﬁer. The ampliﬁer cannot be retained; it must be bypassed or replaced with an aftermarket ampliﬁer. See the vehicle reference chart for wire colors; bypass instructions are not included.  \n• Remove the factory radio.  \nSTEP 1  \n• Unbox the aftermarket radio and locate its main harness.  \n• Refer to the wiring diagram and connect the wires from aftermarket radio main harness to the GM3 T-harness and match the wire functions.  \nSTEP 2  \n• If the vehicle is equipped with an OEM backup camera, connect the backup camera harness to the Human Machine Interface module harness, located at the bottom of the radio cavity. Note: The guide lines of the backup camera will not be retained.  \nNote: if the vehicle does not have the Human Machine Interface module plug the Red connector of the Backup Camera RCA into the red connector coming out the Gray 20 pin of the GM3 harness.  \nSTEP 3  \n• Connect the factory harness to the GM3 T-harness.  \nSTEP 4  \nPlug the climate control portion of the GM3 T-harness into t","cbCaiey9rQcPTzb3","https://ap.wps.com/l/cbCaiey9rQcPTzb3","pdf",3210980,89,"English","# Installation Instructions\n## Before Installing\n## Step 1 - Step 8\n# Wiring Diagram without an Ampliﬁer\n# Wiring Diagram with an Ampliﬁer\n# Radio Wire Reference Chart\n# Vehicle Wire Reference Chart\n# Troubleshooting Table","[{\"question\":\"What should be checked before starting the installation?\",\"answer\":\"Verify the iDatalink Maestro module is programmed with the correct firmware for the vehicle and review the install guide.
