METRA XSVI-2003-NAV Wiring Kit

Buick:

Chevrolet:

The XSVI series interface is an inexpensive solution that provides +12-volt accessory power output for select vehicles that data control signals instead of conventional power signals.

If the vehicle is equipped with retained accessory power features, the XSVI will keep those features. The XSVI-2003-NAV provides VSS, Parking Brake, and Reverse signals to make installing an aftermarket radio with navigation easier.
