Information on Upgrading Certain OnStar® Generation 5 Analog/Digital-Ready Systems to OnStar® Generation 6 Dual-Mode (Analog/Digital) This bulletin is being issued to provide dealer personnel with information and procedures to follow should an owner wish to upgrade their OnStar® Generation 5 analog/digital-ready system to an OnStar® Generation 6 Dual-mode (analog/digital) system.
Service Procedure
Customers who wish to upgrade their vehicle to an OnStar® Generation 6 Dual-mode (analog/digital) system will be required to purchase a 3-year, non-refundable subscription to OnStar®. If they agree to this, they will be eligible for an upgrade, which will be provided to them at no additional cost.
GM bulletins are intended for use by professional technicians, NOT a “do-it-yourselfer”. They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
