This program is only available to dealers located in the United States. Canadian dealers will not be able to order upgrade kits at this time.

This bulletin is being issued to provide dealer personnel with information and procedures to follow should an owner wish to upgrade their OnStarĀ® Generation 5 analog/digital-ready system to an OnStarĀ® Generation 6 Dual-mode (analog/digital) system.

Service Procedure

Customers who wish to upgrade their vehicle to an OnStarĀ® Generation 6 Dual-mode (analog/digital) system will be required to purchase a 3-year, non-refundable, subscription to OnStarĀ®. If they agree to this, they will be eligible for an upgrade, which will be provided to them at no additional cost. This program will be available beginning on March 29, 2005.

Important:: If the customer sells their upgraded vehicle prior to the end of the 3-year subscription, any unused whole months of their subscription can be transferred to their next OnStarĀ®-equipped General Motors vehicle.

Important:: The new Dual-mode (analog/digital) OnStar Vehicle Communication Interface Module (VCIM) that will be installed into the customer's vehicle, as part of this upgrade, will have a new telephone number assigned to it. There is no way to transfer the customer's current telephone number to the new system.

Important:: Only vehicles listed in this bulletin will be eligible for the Digital-upgrade program. Other vehicles are being studied for possible inclusion into the Digital-upgrade program and may be added at a later date. You may also determine vehicle upgradeability by typing the VIN into the appropriate field on www.onstarenrollment.com.

Technicians are to install the OnStarĀ® Digital-upgrade kit using the following procedure:

1. If the customer's vehicle is listed in this bulletin, and they have agreed to sign up for a 3-year, non-refundable subscription to OnStarĀ®, an upgrade kit can be ordered by calling the distributor, Autocraft, at 1-888-947-8100. Upgrade kits will be shipped out within 24 hours and a pre-paid return package label will be included for returning the customer's Generation 5 VCIM. By returning the customer's original VCIM, you will avoid a significant non-return core charge. Refer to the Parts Information table below to determine which OnStarĀ® upgrade kit to order.
2. Once the kit has been received, remove and discard any existing OnStarĀ® Owner's Manuals in the customer's Instrument Panel Compartment. Place the new OnStarĀ® Owner's Manuals from the upgrade kit in the customer's Instrument Panel Compartment.
3. Unscrew the existing analog OnStarĀ® antenna mast from the antenna base and discard. Screw in the provided analog/digital OnStarĀ® antenna mast into the antenna base. This step only applies to the following 2003 model year vehicles (skip to step 4 if the vehicle to be upgraded is not listed below).
