is there anything aprt from the harness i need i have the navi but it seems to light up go on but the radio and the navi doesnt work. Do i need the oem cd from honda japan and is there anything else im missing i need this info asap thanks alot

 

The navi is not going to work. There is no us disk for it. It is just going to show a radom spot in japan. And being a judge for boti car shows. You would get more points for a us model that works vs a jdm unit that does not work. Its pointless imo

 

If you do a Search in Google for: honda navigation dvd it will provide several torrent sources for the dvd. You just need to burn that image to a double layer dvd disk....When the NAV boots up hold MAP-MENU-CANCEL until you get the Diagnostic Screen , Go into version and press download...It will download and install the software needed to update the unit to a USA version.
