Folks, I successfully installed the Sirius Satellite Radio into my 997 via the MOST fiber optic system. I have a 2006 997S with PCM 2.1B. I used the Cayenne Sirius Parts kit. Pix are below and the part numbers are below. Note that this is NOT supported by PAG. It is a custom installation using Cayenne parts. Note also that you must proceed at your own risk. You must have PCM 2.1B. When ordering parts kit, differentiate between XM or Sirius and whether or not you have a CD changer (different part numbers for CD changer or not CD changer). The antenna replaces the NAV antenna under the cowl cover. It works FANTASTIC. p.s. I also included antenna install pix in the cowl cover (under the wipers) (both before and after).

This thread is a Do-It-Yourself installation tutorial for a V1 (or any powered radar detector) hardwire windshield installation to a switched power source at the interior dome light. It is noted that this installation was performed on a 2006 997S with the Self-Dimming Mirrors option. If you do not have this option, I cannot guarantee you will have the necessary wire harness because the switched power source is the same source that powers the self-dimming rear view mirror. As of this posting, I have experienced no side effects. The mirror works and so do the rain sensing wipers (same wire harness). Thanks to member MJONES and TNUNNERY at Rennlist.com for their help, as well as LOREN here at RennTech that gave me the key lead to the possible wire color combinations. Total install time is about 2 hours. Good luck and enjoy!!!! Disclaimer: Naturally, I make no warranties express or implied. I am solely documenting what I did to my own vehicle. I am not affiliated with Porsche. Proceed at your own risk, discretion and abilities!!!! In other words, you are on your own!!! :P Step 1: Locate the straight power wire with the modular connectors on each end. Cut this cable about 6 inches from either end. Strip the wires on the 6" piece to expose the black, yellow, green and red wires. Cut the black and Yellow wires. NOTE: THE GREEN WIRE WILL BE HOT (POSITIVE) AND THE RED WIRE WILL BE GROUND (NEGATIVE) DURING THE REMAINDER OF THE INSTALL. Coat the ends of the green and red wires with solder using a soldering iron. Step 2: Locate the direct wire harness, and cut the red fuse red wire leaving about 3 inches on each end. Then cut the black wire to have about 4 inches of wire. Strip both ends on each wire and coat the bare ends with solder using a soldering iron. Step 3: Remove the dome light assembly by pulling down on the plastic assembly at the point near the windshield. Step 4: Pass the modular wire you prepared between the windshield and the dome light assembly housing so that the modular plug is hanging in front of the windshield and the bare wires are inside the light assembly housing. Step 5: Now, use a blanket to cover the interior of the car in case you drip some solder. Then, solder one end of the red wire with the fuse to the green wire on the modular wire assembly. Next, solder one end of the black wire you prepared to the red wire on the modular wire assembly. Let it cool, and use either heat shrink tubing or electrical tape and tape it up. Step 6: Locate the 10 wire harness inside the dome light assembly (there are only 9 wires in there) and remove the black tape carefully with a project knife. The wire at pin 2 is switched 12VDC (THIS WIRE IS BLACK / ORANGE and the wire at pin 10 is ground (THIS WIRE IS BROWN). THERE ARE PIN NUMBERS ON THE SOCKET. NOTE: LOOK AT THE WIRES GOING DOWN TO THE MIRROR - NOT THE WIRES THAT GO UP INTO THE ROOF WHICH ARE DIFFERENT COLORS). You really wont get this wrong - its pretty intuitive (yeah right - now that we know which wires they are - this is the magic here). Step 7: Using wire cutters, CAREFULLY cut 1/4 way down on the wire to 'grip' and 'pull' the insulation back on each of the two wires. Apply solder to the bare wire. If you cut it by accident, it will blow up in 5 seconds. GET OUT OF THE GARAGE. Kidding. If you cut it, just twist the ends back together, but what you want to do is solder the remaining end of the red fuse wire to the ORANGE / BLACK wire and the other end of the black wire to the BROWN wire. Then, apply tape or shrink tubing. Do it slowly and neatly. After this step, plug the modular plug into the V1 and it should NOT work (no key in ignition). Then place the key in the ignition and turn the key on and it SHOULD work!! If it doesn't, you probably did not turn on the V1 or you got the polarities reversed (this happened to me because the cable to power the V1 is actually a crossover modular cable - - but follow these instructions and you will be OK). Step 8: Pack it all back in the dome light assembly neatly and replace the dome light. Step 9: Test your work and take a look. You now have a hardwire switched V1 with no cables!!!! And, That's it!!! Enjoy!!!! - Adam
