Navigation System

This unit contains the factory touchscreen navigation interface.

GPS navigation operation requires the compatible GM navigation map disc and vehicle navigation equipment.

Navigation map coverage and software versions vary by model year and region.

Navigation Disc

Navigation map DVD is included only when specifically stated with the product.

The system requires a compatible GM navigation disc for navigation operation.

Incorrect or incompatible map media may result in navigation errors or failure to load maps.

VIN / Theft Lock Programming

GM factory radios are electronically linked to the vehicle identification number.

A used replacement navigation radio may display:

LOCKED

or

THEFTLOCK

after installation into another vehicle.

Vehicle-specific programming may be required to clear the donor VIN and configure the radio for the receiving vehicle.

Programming may require:

• GM-compatible diagnostic equipment
• SPS programming
• VIN configuration
• Radio setup
• Vehicle-option configuration

Professional installation and programming are recommended.

Bose Audio System

This radio is commonly used in vehicles equipped with the factory Bose premium audio system.

The factory Bose system uses an external amplifier.

Vehicle audio configuration should be verified before installation because Bose and non-Bose vehicles can use different system programming and audio signal levels.
