Congradulations on your purchase! If you didn't get the 3 Owners Manuals, download them from elsewhere on this site. It has the remote access programming procedure. Up to 4 remotes can be programmed so you may need to clear them all and start from scratch because remotes 3 & 4 don't get associated with a driver or remote-start the car.

The manual says you are entitled 2 Nav updates but last I checked the Website, the most current is back-ordered. I highly recommend the VIN-check thread on the CTS-V area of this forum. It will show the Dealer-performed maintenance history of your car and the 'Inservice date'. This date drives your warranty and Nav update qualifications.

Cliff handled your other question. Why not ante-up to Supporting Membership status. The site may be free but it costs $ to run.

Happy Motoring.
