Map CDs
WARNING: This page is about a different car, the 2003 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
There are 9 regional CDs and 1 interstate/major city CD. The correct CD must be inserted to find locations in the specific region. The major city/interstate CD should only be used for traveling from region to region. Once the vehicle has traveled to a new region the appropriate CD must be loaded.
