All vehicles equipped with OnStar® listed in this bulletin were built with Analog-Only OnStar® Hardware. OnStar® equipped vehicles with analog-only equipment were designed to operate only on the analog wireless network and cannot be upgraded
for digital network compatibility.
Vehicles with this equipment will no longer be able to receive OnStar® services beginning January 1, 2008. At that time, service will be available only through Dual-Mode (Analog / Digital) equipment. Analog-Only vehicles cannot be upgraded to
digital equipment.
