monitor the Tech2(R) for the current time and date. REMINDER - Keep in mind that the time displayed on the Tech2(R) is in Greenwich Mean Time
(GMT) and the offset is based on the time zones relationship to GMT.
If replacement of the VIU/VCIM is necessary, you MUST reconfigure the OnStar® system. Failure to reconfigure the system will result in an additional
customer visit for repair. OnStar® VIU, Generations 2 and 3, will require the technician to press the blue OnStar® button to reconfigure the vehicle with
an OnStar® advisor.
OnStar(R) VCIM, Generations 4-7 will require the technician to reconfigure the vehicle with the use of the TIS2WEB and SPS applications (pass thru
only), along with the Tech2(R).
The configuration and set-up procedure is a two-step process that must be completed step-by-step without interruption or delay in between each step.
This procedure enables an automated activation without a button press by the technician to the OnStar(R) Call Center. Following this procedure, it may
take up to 24 hours for all OnStar(R) services to be fully activated.
How to Order Parts
If the OnStar(R) GPS date/time stamp is non-recoverable and the unit needs to be replaced, dealers in the U.S. should contact Autocraft Electronics
