As you can see on the Gnomecam, I had a 2 hour GPS navigation install odyssey from 6pm - 8pm today. The odyssey began with my DDX-7015 head unit which accepts a KNA-V2100 navigation system. The $800 MSRP had prevented me from adding it on, especially since my laptop does GPS just fine thank you, but a used one on eBay for an affordable price made me change my mind. After making all the connections for my test run I was rewarded with absolutely no change in available modes for my head unit. After taking my frustration out on Lisa and making her cry, I decided to try various settings and discovered I needed to change the video source. Just like that the nav was working properly. I still need to find a place to hide the nav unit itself, but the end result of an integrated navigation with no exposed power cords, wires or extra monitors is very hot. I even hooked up my illumination signal and it's smart enough to switch to "night mode" when I turn on the headlights. The only downside being the included map disk is 6 years old, so if anyone has a KNA-MP215 map disc just laying around unused, let me know.
