Hi Gatornail:
___I cannot give you any input in regards to the Pioneer system but having used the Honda/Acura NAVI (easily the best in the OEM business); there are shortfalls vs. a PDA based - GPS NAVI solution like Mapopolis on a Windows based PDA w/ a Sirf IIe/LP chipset or newer GPS Receiver. I have used Mapopolis with various PDA’s and GPS receivers in the Insight, Ranger, and MDX with excellent results vs. the sometimes featureless/feature-full Honda NAVI in the PZEV Accord.
___For a somewhat detailed list of HW and installation suggestions, the following link might be of interest?

___Scroll down a bit for my own setup as well as the installed – attached pic as it sits in the MDX today.
___Good Luck
