I started this project about a month ago, I did not work on this everyday and I actually had a few weeks in between. Overall I spent about a total of a weekends worth of removal and install time, and about another weekends worth of time trouble shooting. In the end I am very happy with end result, it may not be 100% perfect but it is still in the A+ category for me!
What I had:
OEM Porsche PCM System - Navi, CD Changer and Bose Speaker & Amp. I also had installed a iPod adapter that took the CD changers place, I was able to control iPod via PCM
What I installed:
Kenwood DNX 9960 , Sirius Sat Radio, HD Radio, Monitor in motion bypass, rear center console DVD/Monitor, NAV-TV MOST-HUR controller, Face Plate from the UK
The Kenwood has built in BT for hands free phone and BT audio streaming, iPod audio/video, DVD and Garmin Navigation. It also can have Siruis, XM or HD radio tuners. I bought the Sirius and the HD and found out later that I had to choose because they dont have a switch yet. I chose Sirius SAT.
Installing the GPS and SAT antennas was quite easy, espeically the SAT antenna due to how thin it was and how much cable length. It would have been a straight forward install if it was not for the NAV-TV MOSTHUR. We could not get the first one to work, after too many calls to customer service I was about to give up. It would just not produce sound, I thought it was not turning the amp on. So they sent me another unit and it worked great. We just thought I had a defective unit. It was not until I was adjusting the settings via laptop that I realized the real issue. When you get the MOST-HUR you have to program it for Alpine or Kenwood (if you want to retain steering controls) you can also adjust power out put to amp. Thier range is from 70-210, it comes set at 78. When I had the first one I programmed and did all the pre-wiring in my office. I had preset the audio to 140 and figured I would increase from there. When i had my replacement unit I just connected it to see if it would even work. Then I went to adjust because the vol set at max was really at 75% or less old vol. When I adjusted to 140 no sound, 120 same, so I did 100 and about blew the speakers. I have it now adjsuted to 86 and I am happy with it. They need to mod thier instructions and lower thier range for Cayennes to 70-100.
The voice control and hands free phone is such a treat, so is the navigation. I can actually look up points of interest via detailed category. The best part is the touch screen and being able to use the steering controls. Especially the scan buttons. You can set the Kenwood to scan either by #, station or programed pre-sets which is what I did. So you can just toggle between your 6 pre-sets instead of scanning through all the stations. I installed the video in motion bypass for the fun of it, my wife likes watching comedy concerts on long trips. I was also able to match the boot screen to the original PCM boot screen and add a Porsche background to menu. I also found a Cayenne Turbo icon for the Navi, changed the color from tan to grey to match my Cayenne.
The center console is a 8" monitior with built-in DVD and FM modulator. It has IR for head phones and built in speakers. It also has USB and SD ports, as well as Video in and out. It can be folded out of the way and rotated all around.
I think this was well worth the cost, I was able to keep my Bose system and steering controls. The total cost was less than trying to upgrade to a PCM DVD or the new touch screen PCM plus I still don't think it would compare to my current set up.
If anyone needs help with their install just let me know. I feel like a engineer after dealing with the wiring trouble shooting etc. I have included some pics:
