Can i get map update CD

Sounds like a concern with the navigation system DVD or CD reader itself. I've seen this before where it suggests the disc is dirty, and it's more a problem with the unit itself. With the age of the vehicle, repair or replacement of this component with any factory parts seems ineffective at best, because the information and systems are obsolete compared to modern phone based navigation. You may be able to purchase an aftermarket unit with Apple CarPlay or Android Auto capabilities - worth looking into.
