4.1 Pre-Installation Steps

1. Disconnect Battery: Disconnect the negative terminal of your vehicle's battery.
2. Remove Factory Radio: Carefully remove the existing factory radio and trim panels. This may involve removing screws, clips, and potentially modifying the dashboard opening for the new unit. For Jeep Grand Cherokee 1999-2004, you may need to remove factory vents by drilling or using a Dremel, then mounting them to this unit.
3. Inspect Wiring: Familiarize yourself with the vehicle's wiring harness.

4.2 Wiring Connections

Connect the provided wiring harness to the car radio and then to the vehicle's factory harness. Ensure all connections are secure. Key connections include:

• Antenna: Connect the radio antenna.
• GPS Antenna: Mount the GPS antenna in a location with a clear view of the sky (e.g., dashboard, under windshield).

• Steering Wheel Control (SWC): Connect SWC wires if your vehicle supports it. Programming will be done in the settings.
