Is it possible to add custom POI's to the in dash GPS units in the GMC Denali? How do you go about updating the maps in this unit as well?

Thanks in advance.

Not Sure

I have an 08 Silverado and I'm not sure if you can add POI's or not...........I am thinking not unless you had a new CD to put in..........maybe somebody who knows more will fill us in........Dave
