Navtool, product good, guy selling a a**hole. Now it may make a difference if you make sure to buy every option & connector from him. I think folks trying to save money or just not buying all the wiring harnesses they need are the ones having trouble. If you communicate with him on Facebook, you will get discounts offered. So far I do not have this generation Odyssey, but did look into it because my wife has an Acura with the same dual screen set up. Hers has Navigation with all the limitations the Odyssey NAV has. The NavTool will allow you to have any map app that is on your phone display in the upper screen. I think the youtube video NavTool has shows the Acura MDX. Also the same set up as this generation Odyssey.

The loss of the rear camera is from replacing the entire audio system with a Kenwood in the example above. The Navtool add on keeps the rear camera and adds inputs for additional cameras. Unless you are going to tear into your dash and add all the boxes and wiring harnesses yourself, I would start with some car audio installers that are local.
