Hello,

I had to do this research for another member today who contacted me via pm and had purchased a navigation drive and PCM on ebay, but did not have the accompanying parts needed to install. So I am including the parts list and retail prices here for anybody else that runs into this situation.

Of course you will need a PCM 2.1 unit, and a navigation drive (997.642.157.00 is the part number listed for the Cayman and it retails for $1824.47)

You need one of the following waveguides (MOST optical cable harness) depending on your situation:

997.622.710.00 (Bose, no changer): $99.87
997.622.713.00 (Bose, changer): $116.55

997.622.707.00 (no changer, no Bose): $99.87
997.622.715.00 (changer, no Bose): $99.87

You need the following parts, some could be replaced generically (nuts, screws, tie wraps).

997.642.105.00 - GPS Antenna - $71.48
999.507.441.02 - Speed Nut (price unlisted)
999.073.210.00 - Tapping Screw - $0.21
997.642.231.00 - Nav. unit retaining frame $19.05
997.642.257.03 - Navigation Disk - $547.34
997.612.331.00 - Wire harness (electrical/antenna) - $33.74
999.513.051.40 - tie wraps - $0.54

electrical tape\adhesive compound.

For detailed installation instructions with pictures, please see K-Man S's installation article here.

Good luck,

Suneet

2006 - 2008 Caymans also came with the DVD drive with part number 997.642.137.02 . I will be retrofitting my Cayman with this part shortly and will verify that it works :)

Good question... the disks are made by navteq, just like most other (at least German) manufacturers. But I'm not sure if you pop in say, a bmw navteq dvd, that it would work in the Cayman. Keep in mind these navigation disks are really only about $100-200 on ebay.

I have a PCM 2.1 unit without navigation, do you also need a 'navigation module' that fits into the cavity in the bottom back of the PCM unit?
Thanks

No but you need the DVD unit that fits in the trunk together with the GPS aerial etc.

The module you are refering to, was the way it was done in the old PCM that was fitted to the 986 and 996.

Just another point to mention. The PCM's are configured at the factory either with or without Bose. If you have a Bose amp already in the car you will need a corresponding BOSE configured PCM. likewise if you do not have bose then you wont be able to hear anything out of a Bose configured PCM without the amp. The bose units typically have the number 3 as the 6th digit on the part number.

While that is true for it to work out of the box; the dealer can program any PCM unit to work with the Bose. When I first installed my PCM out of a 997 with sound package plus, I had no sound but the PCM was functioning correctly. The dealer used PIWIS to tell the car\headunit to use the Bose amplifier instead of the speaker outputs.

Just a note for the forums body of knowledge ...

The optical wavguide 997.622.713.00 for Bose with a CD changer has 4 connections. One connection routes to the PCM, another to the Bose Amp, one to the Nav drive, and one to the CD Changer (or Dension). If you wanted to install a Dension unit on a car without a CD Changer but with Bose and wanted to use factory fiber, you could probably pick up the 997.622.710.00 waveguide. It should have 3 connections instead of 4.

If you are going to attempt this one get ready for scraped knuckles and an urge to scream! I just installed Nav to my self installed PCM and damn it was hell. What I ended up doing to get the wave guide disconnected from behind the brake booster is cutting the ties with a tiny front bladed scalpel to get at the connection. Wish I thought of it earlier. It all works a treat now though, takes a while to calibrate, it thought I was in Alabama when I first turned it on.

Made the mistake of closing the front trunk with the battery disconnected.

Cried.

Called Triple A.

Fiddliest job ever!

When I originally installed the Dension, I had to get that waveguide clip off from behind the brake booster. I wound up breaking the clip, which made this round much easier. I'm pretty sure I had a few scrapes when I did that. Then again, if I had a scalpel in my toolbox it may have been more fun :)

Hi Guys,
I recently bought the DVD navigator for my PCM. The problem that I am having right now is that I order the wrong fiber optic (997.622.707.00 no changer, no Bose) instead of (997.622.710.00 Bose, no changer), so my question is do I need to reorder the fiber optic or I can use the one I have now. Thanks in advance.

Mendible I'm not positive but probably yes; but you should try hooking it up to the MOST connector in the front boot brake booster and see if everything works properly. If not, then return it; as I believe the proper one for the Bose amp hooks up to the amplifier.

I just did this install using the above parts list. It really made things simple to know that I had all of the right parts. The only thing that I did not have were the clips to secure the Nav Drive cage to the frame of the car. Were they supposed to come with the frame? It was nothing a little bit of double sided Velcro and a few zip ties couldn't fix, but I thought that it was odd.

Thanks smounic. Right now it all seems to be staying together pretty well. However, if I know myself, the OCD in me will drive me crazy until I order the "Porsche Part" and redo it. After all, at this point I have gotten the removal of the front plastic cover down to about 5 minutes. I'll probably be calling Ric at Suncoast in the AM........
