WARNING: This page is about a different car, the 2004 GMC Sierra, 2004 GMC Cab & Chassis Sierra, 2004 Chevrolet Silverado, and 2004 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
The Generation 5 and Generation 6 vehicle communication interface modules (VCIM) utilize 2 numbers for cellular device identification, call routing and connection, a mobile identification number (MIN) and a mobile directory number (MDN). The MIN represents the number used by the cellular carrier for call routing purposes while the MDN represents the number dialed to reach the cellular devise. Although technicians have the capability to change these numbers by means of the scan tool, this should ONLY be done at the direction of and with explicit instruction from General Motors Technical Assistance Center (GM TAC).

| Say each number clearly, pausing until the system confirms receipt of the number. With Generation 6, OnStar will understand all digits spoken continuously, without the pauses and repetition in between. |
The system will repeat the number stated. If the number was not heard or understood, the system will state the word "number" prompting the user to repeat the last number. |
