OEM Communication Module 15204260

This factory radio communication module carries part number 15204260 and serves as a direct replacement for the original unit in select vehicles. It is intended for owners of a 2003 Hummer H2 or a 2004 GMC Canyon and Chevrolet Colorado who need to restore OnStar functionality. The module requires the exact part number match to operate correctly.

Passive Electronic Operation

As a solid-state communication module, the unit draws minimal power from the vehicle electrical system and produces no audible noise during normal use. It contains no moving parts, so thermal output is negligible and no active cooling is required. Installation does not alter the vehicle's existing power distribution or acoustic profile.

Direct Plug-In Replacement

The module installs into the factory location using the original connector and requires no programming or coding after fitment. It frees the owner from dealer-only diagnostics by restoring communication capability without additional hardware. Buyers who need Bluetooth, AUX input or a combined radio and display unit will not find those features here. Compatibility is limited to the specific models and years listed.

Questions about this item

How do I install the 15204260 communication module in my 2004 Chevrolet Colorado, and what step is often missed?

Mount the module in the factory location, connect the factory harness, then verify the part number 15204260 matches the original unit; skipping the part-number check is the step most installers miss.

What maintenance or replacement will the 15204260 communication module need over time?

The module itself is a sealed OEM unit with no user-serviceable parts; replacement is only required if the unit fails or if the vehicle's option code UE1 configuration changes.

What limit appears first when the 15204260 communication module runs continuously in a 2003 Hummer H2?

The module operates within the vehicle's electrical system, so the first limit under sustained use is the vehicle's charging-system capacity and wiring integrity.
