I picked up an ancient old Alpine NVA-N751A CD-ROM based navigation for my other car. I figured something old and cheap would be fine for in-town driving.

Anyone know where I can pick up the CD's for it for free or super cheap?

ebay

Thanks, but I already got rid of it.

just wondering why you decided to get rid of it? i thought alpine makes the best navigation

The cost of CDs, wire harness, GPS antenna, and all the other accessories would have cost me more than buying a second-hand Pioneer DVD navigation.
Not to mention I think the newest CDs for it were almost 5yrs old.
