I bought an '07 QP last year and like both of you I discovered navi cd's were missing. I felt a burning need to get them and make the car 'complete'. I was fortunate to find a set for sale by a member here and bought them.
Unlike my Honda Ridgeline that has a single navi CD, these cars have a collection of CD'.s For example the CD I used covers FL, GA, SC, AL, etc - several of the southeastern states. The full set is a collection of CD's that break US up in to 7-8 CDs (not a single DVD). That is why you'll see single CD's for sale on eBay. Sellers keep the CD for their area and unload the rest. All that said - I'm happy to sell you my set of CD's. I bought them, installed the FL CD, and after seeing how amateur the resolution and outdated these are with relation to new road construction - they are absolutely useless. I've never used a single one other than the day they arrived to see how it worked. Once you do install a cd, figuring out how to navigate and enter an address is arguably the worst user interface I've ever encountered. I use my iPhone and Google's Map's with free turn-by-turn voice directions. My advice - find something much cooler to spend money on like LED lights for the footwells, courtesy lights, under mirror lights, etc and replace those yellowish factory bulbs.
