Howdy folks. I decided to spring for the NAVTOOL interface for my new (to me) 2015 AWD Pilot Touring with nav. Basically, this gadget places itself between the radio and the display, and allows you to run Android Auto on the big screen. Big mistake. They have hundreds of installation videos that claim to be for the exact system you are installing, and it should be easy as pie. Once the unit arrived ($500 later), dug in. After getting everything taken apart, I find that the video is asking me to connect a 14 pin connector that doesn't exist. I turn it on with what I've got, and the dsplays blink a couple of times, and then go dark. The only help I got from "customer no service" telling me I needed to connect 4 wires that were never mentioned in the video (and the non-existent installation manual). I did that, with no change. They went silent on me, so I decided to pull it all out and try again in the daylight tomorrow. Pulled it all out, and the displays are still dead (and radio). I check the number 17 fuse in the triangular fuse box under the hood (good) and all others in that fuse box. Anyone have any ideas on what this might be? I'm seriously doubting this outfit is going to lift a finger to help.
