Wanted: Navigation CD

Just bought a 2005 Dodge Durango but it was missing the
Navigation CD. The dealer wants $125 for one.
Does anyone have one they're not using or anyone upgraded
to the newer copy AD and no longer need the AC copy.

Part number should be 05054033AC or AD

Thanks in advance.

Thanks for the related links but I only need the CD and
according to the user manual it will only work with the
one supplied by chrysler/dodge.
