Hi everyone, I'm so flattered you linked to my article. Thank you! I hope you found it helpful. I wanted to mention that I also made a video on this too in case you don't have the ability to actually see this stuff in action on display in a store. There is a link on my website in the beginning of that post to the video. Being a newbie on this forum, I didn't think it would be appropriate to post a direct link.
I do this stuff every day and sell all three brands so I'm happy to answer any questions anyone might have here on the forum. I will add one more thing to this conversation. Aesthetically talking, in the Porsche with either the matte black finish dash kit or factory matched silver dash kit, I do think the Alpine or the full 7" Kenwood or any Pioneer NEX model looks cleaner than the DNX691HD. Kenwood uses a shiny black finish on their eXcelon product and it would drive me nuts against either matte black or silver dash kit. It's the little things sometimes that make a big difference. Thanks again for linking to my site
