How To Install Satellite Radio to a 987 Cayman S For Native PCM Integr

Recommended Posts

I have read all of the posts regarding this subject on Renntech.org and Planet-9.com as well as other internet forums and discussions with third party manufacturers such as mObridge. I have found one post that was particularly helpful – musclehedz101 on Renntech.org – as a followup to my post titled – “xm / sirius install w/ pcm 2.1 cayenne kit vs. nav-tv sirpor2 vs. itronic” dated 7 November 2010. His post was based for a 997 (2007 C4S) with a cd changer installed. I decided to go with the Porsche Cayenne unit rather than one of the 3rd party vendors. Yes the Porsche Sirius tuner is still available - just not the Cayenne kit ... but it is much less expensive to buy the tuner and the harness without buying the kit.

I should note that I have a 2006 Cayman S with PCM 2.1, Bose and many other options including mObridge ipod / Bluetooth combination unit, however I do NOT have a cd changer, and do not have TPMS. I will give you the disclaimer you that what I have written worked for me – I will caution you to proceed at your own risk.

The parts you will need are:

955.645.280.02 Porsche Sirius Receiver or (955.645.281.02 Porsche XM Receiver)

955.044.900.65 Porsche Harness for Installation (with CD changer)

Single to Dual Sirius Antenna Adapter http://www.tss-radio.com/products/sirius-dual-to-single-antenna-adapter

Sirius magnetic antenna http://www.tss-radio.com/products/search/browning-magnetic-car-antenna-for-sirius

(there are several out there, I chose the Tram ... just make sure its made for Sirius, unless you are installing XM).

I would recommend that you contact Jeff at Sunset Imports (Renntech.org members know what I am talking about) for the Porsche parts.

I have chosen to mount the receiver on top of the nav dvd unit in the front luggage compartment. I have mounted the antenna on the underside of the cowl (between the windshield wipers). If I run into any interference, I will relocate it above the cowl, but I prefer to leave it concealed if possible.

First remove the cover around the nav dvd player – remove the 8 screws and gently start pulling the front left (passenger side) up, separating it from the perimeter gasket – then carefully unplug the trunk light. It may help to remove the Nav access panels. Next, remove the battery cover and the two side panels. Now is a good time to unplug the battery and remove it. Next, you will need to remove the cowl (if you are going to install the antenna on the underside). The first step is to remove the plastic caps covering the nuts on the windshield wipers, then remove the bolts and the wipers (simply pull them toward you – be careful not to drop it on the hood). Pull the plastic pin rivets from the bottom braces (behind the battery), disconnect the electrical connections for the washers and the water supply. Remove the caps on either side and remove the 10mm nuts and the torx screw at the middle top. Then carefully pick up the cover and reach underneath (on the passenger side) to disconnect the NAV antenna (pull off) ... then gently remove the cover (it may take some gentle “back-and-forth” moving). Mount the antenna next to the NAV antenna and route the cable toward the trunk side. Reinstall the cover at the windshield, reattaching all that you disconnected for the cowl removal. Leave the battery DISCONNECTED.

Next its time to connect the power and the fiber harness. This is much easier and quicker with the factory harness since it has connections to receive the power and fiber optic connections that powered the NAV drive and connect them back to the NAV and then connect to the Satellite tuner.

1. Disconnect fiber cable MOST connector from the back of the NAV drive. (It may be easier if you remove the NAV drive). Be careful with the fiber cable not do damage the end or kink the cable. When you remove the fiber cable from the back of the NAV drive, you will notice that it looks different from your new harness – that is because the new cable has protective ends that must be removed.

2. Plug the MOST Cable into one end of the new Fiber Harness (on the “Y” end), and plug the other end (of the “Y” end) into the NAV drive. Now connect the long singular end of the Fiber Harness into the back of the Satellite tuner.

3. Locate the CD changer power supply cable on the far left (passenger side) of luggage compartment. Connect the power from the “Y” end of the power cable to the CD changer power cable. (if you have a CD changer, then disconnect the power supply and connect the harness – then connect the other power end of the “Y” end of the harness into CD changer).

4. Now connect the long singular end into the back of the Satellite tuner.

5. Plug the antenna adapter to the back of the satellite tuner. The dual leads must be connecting to the corresponding tuner leads – white goes to green (terrestrial lead) – gold goes to brown (satellite lead). I had to cut off the gold cover to get it to fit onto the tuner.

6. After everything below is completed and the tuner is mounted, you will need to manage the excess cable with cable ties as well as secure the antenna adapter.

It is now time to route the antenna cable into the luggage compartment. The best path is thru the rubber grommet. Once routed into the compartment, plug antenna cable into single end of antenna adapter. I chose to mount the tuner to the top of the NAV drive with Velcro ... you could use double stick foam tape.

Reconnect the battery and test the installation prior to reinstalling the panels. To access the Satellite function, turn on the PCM and press the “AM/FM” button – cycling through the modes until you see the satellite radio function appear. If “Satellite” doesn’t appear, you will have to have your dealer program the PCM to acknowledge and recognize the OEM tuner has been added into the network. Mine came right on without needing to get the PCM reset.

Next you will need to contact your satellite provider (Sirius or XM) to activate the tuner. You will need the serial number on top of the tuner. Make sure the radio is on when you call to activate.
