I finally got around to installing my 8000NEX in my Forester over the memorial weekend. I did a full write up on the Forester forums: http://www.subaruforester.org/vbulletin/f77/pioneer-nex-powered-subwoofer-install-338858/
So far I'm liking it a lot. I do have my VSS connected correctly and it shows up in the status screen but my map positioning seems to be off a bit. Waiting till the 3D calibration status to complete and hopefully it resolves itself after putting on enough miles.
I did get a bit frustrated when using the navigation system coming home from work on Tuesday because it kept trying to put me on a back road. Finally realized it was due to me leaving the default traffic setting of "Offer Detour if it Saves at Least" to 5 minutes. The following day I increased that to 15 minutes and it left me on the highway.
I'm using an iPhone5s with the unit. If I remember correctly, I read a few posts awhile ago that you have to change smartphone settings from USB or bluetooth depending on actual connection. I have that set to USB and I'm actually able to listen to my iPhone music via USB or bluetooth. Comes in handy when I know I'm doing a quick 5-10 minute drive and don't have to bother taking my phone out of my pocket.
