OEM OnStar Module for 2007-2008 GM Vehicles

This factory communication module carries part number 25826499 and is listed as a new OEM unit. It provides OnStar and navigation functions for compatible Chevrolet, GMC, Cadillac, Buick and Saab models from the 2007 and 2008 model years.

Suits owners needing an exact replacement

Buyers must already have part number 25826499 installed; the unit will not function if the vehicle uses a different part number or data stream. Vehicles equipped with external amplifiers or differing communication protocols should look elsewhere, as interchangeability is not guaranteed even when connectors appear identical.

Direct swap for factory radio stack

The module plugs into the existing dashboard harness without additional coding. It restores OnStar communication and navigation features while freeing the owner from dealer programming fees, provided the original part number matches exactly.
