Just realized this was for a 997-2. They switched to touch screen, etc, that year, right? So with that said, I can't speak with much intelligence around what is/isn't possible.

So I retrofitted Nav and cd changer into my wife's 2008 997.1 C4S . This was in 2009 when the car was bought new and even still had the temporary paper plates on it. You should not need to replace the PCM. You just need a lot of parts, a lot of time, and the dealer to set coding in the car to say you now have Nav. Suncoast and @Loren were great resources to me at the time but I also had the electronic parts manual which told me pretty much everything I needed to know.

I'm looking at possibly moving into a 987CS2 and was curious about the LSD option. Being as it's almost impossible to find one on the lot with the factory LSD, I was curious for opinions as to whether it's worth it to hunt down a 987CS2 with the factory option or is it better to go with aftermarket (quaife, etc)?

I have tried the same installation, and everything fits as described here, however I am not able to access the XM tuner from the radio. I am pressing either the FM or AM button to cycle but I do not get it to display or activate. If I press TRIP/MAIN, I can see that the PCM lists the Sat Radio as FOUND and ENTERED. I have PCM ver 2.1 with no phone button.

Any suggestions/Help?

Did you go to the dealer and have your system coded to accept the new Sat unit?

ATE Gold is the factory fill.

That's what I was looking for. Thanks, Loren!

To be more specific, the Pentosin I have on hand is "Pentosin Racing Brake Fluid". I know from research that it appears most Porsches take Pentosin 11S (which can be replaced or mixed with the higher 202), but I can't figure out how the "Racing Brake Fluid" fits into that equation...

I'd like to top off my girlfriend's 997-1 C4S but I only have Pentosin, ATE Super Blue, and ATE Gold laying around (listed in order of heat rating). Are any of these ok to mix in with whatever is stock?

Thanks!

Thanks. I went out to my car and it will display artist. Still curious about installing Nav from a 2005 cayenne into 2006 carrera???

How do you go the info page? Can I install a factory DVD nav unit from a 2005 Cayenne S into a 2006 Carrera? THANKS

I installed cayenne XM recently into my 2006 Carrera and it works great. I have no bose or CD player. In this setup you want just the straight fiber optic cable NOT the Y shaped one.Dealer had to activate. I added a power amp and 6 inch narrow profile kicker sub woofer in a custom enclosure on shelf behind rear seats. I think the system sounds better thante factory bose. Can anyone see the artist name on the PCM screen? It seems only the name of the station comes up.

I had the same question you did about the Cayenne Sirius system I retrofitted. It appears your XM works the same way...in that the song info only appears on the Info/RadioText screen. I verified on the Cayenne boards that this is how it works (i.e. they never see the song info scroll...the cluster and the PCM always just display the station name when on the "normal"/Main screen)

Frequency is country specific.

Hmm so maybe the part numbers I listed... one is for US, and the other for Canada, then...

So I just finished retro-fitting Sirius, Cd-Changer and Sat-Nav into my girlfriend's 2008 997-1 with no issues and after dealer coding, everything appears to be working great. Before the retrofit, the basic PCM setup was at Level C . It so happens that I had special ordered a new vertical Navigation-DVD unit for the retrofit. I performed no PCM updates , system, navigation or otherwise, and the Map disc I'm using is a 2006 disc. The reason I bring all this up is that my experience seems a bit counter to some of the notions expressed in this thread.

I haven't checked the software-versions post retro-fit, but according to what I've learned from this thread and others, all components have to be at a matching "level" to talk to eachother, so knowing that pre-retro-fit that the car was at Level C, this would mean the Navigation drive would also have to be at Level C in order to properly talk to the existing system. Where things get contrary is that, also according to this thread, a Level-C system can't use a 2006 disc, but I, in fact, am.

I may be over-simplifying so maybe I'm missing something?

I have a 2006 Carrera bought in the USA and made to US Specification. I have moved, with the car, to the UK. Garage door openers in the USA are on a different frequency from the Rest of the World (RoW). The frequency for the US spec Homelink system is different from the frequency for the RoW Homelink system. I took the car to the dealer who hooked up the progaming box and, although there is the option to change the Homelink setup from USA to RoW, the command cannot be executed becasue the car is fitted with a USA Homelink module. I therefore need to change the Homelink module from USA to RoW. What parts will I need?

I know the part number for the US unit is 997 618 227 01 "control unit garage door opener" with an additional info item of I607: "Garage door opener 'Homelink', 315 Mhz"

I see another part number listed 997 618 225 02 "control unit garage door opener" with an additional info item of I608: "Garage door opener 'Homelink', 433 Mhz"

Since I know the first part is for US, then my assumption would be that the second part (997 618 225 02) is RoW

You should verify this, though, before ordering :)

Apologies for cross-posting between threads, but I need to complete my install tomorrow morning so I need answers semi-ASAP. I'm retrofitting Nav, Changer, and Sirius all at the same time and my last big question is where the Sirius unit fits in the MOST path. Without Sirius, the path is PCM -> Amp -> Changer ->Navigation so where in there would the Sirius unit fit? Thanks!

Just got back from getting everything coded at the local dealer and it looks like I was correct in my assumption that the MOST path should be PCM -> Amp -> Changer ->Sirius -> Sat-Navigation.

My only question is why isn't the artist/song information displayed on the "Main" screen? (I have to go to Info->Radio Text to see the information). Anyone have any idea here?

As to the Optical waveguide or MOST fibre optic , yes there is a set sequence, PCM - AMP -CD - NAVIGATION. The telephone module is also optical waveguide but this is on a different loop.

Berty,

Where in this order would the SIRIUS fit? My un-educated guess would put it between CD and NAVIGATION so PCM -> AMP -> CD Changer -> Navigation but I'd like some confirmation before I button the boot up.

Thanks Berty, and everyone else who has so far contributed to my endeavor. Also many thanks to PorscheLibrarian who got me updated information that I had so far been unable to find and updated TSBs that listed current/newer part numbers than what's in the Member TSB section. (As an aside, here, would it be possible to update the TSBs that are already in the member section to the current ones?)

All the TSBs we have here are as current as what Porsche gives dealers/OPCs. We get them at the same time they do.

Sometimes it takes Porsche a few months to update them.

Loren, my apologies, you are completely correct. I was confusing the (outdated) printed instructions that were included with my purchase with what was available here. Membership definitely has its benefits :renntech: :)

Ah yes, sorry about that I can now see where you are looking at. The part number 997 642 139 02 is for the earlier chassis numbers and the 997 642 159 00 is for the later ones. Check your chassis number against the details , this should steer you in the right direction. If you are intent no an OEM look then you will need a vertical mount unit appropriate to the PCM and chassis number of your car. Otherwise I think the horizontal unit from the cayenned will wor if you can fix it horizontally.

I am going to go ahead and pick up the Vertical 997 642 159 01 unit from Suncoast and I have now listed the horizontal one for sale here on RENNTECH: LINK .

One final comment, from my VIN, I determined the chassis code is 998S732132 but I haven't been able to find any PETs that list a code in the description that starts with 998 (they're all either 996 or 997 so MY06 or MY07)...I'm going to assume this is because the three I'm looking at (Porsche.com, AutoAtlanta.com, and the actual PET program I received) are all outdated...Is this a correct assumption?

From the link you posted there is no item 3 for a vertical DVD device, item 3 is the support bracket.

Berty, there's a second diagram of components in the link that does list the vertical drive that you're missing. It's after the diagram and subsequent detail that shows only the horizontal drive. 911-01 on page 423 of the PDF as opposed to the 911-00 on page 419 you're looking at.

First - I promise I'm not dense, I've searched for answers (even simple things like determining chassis number) and have come up fairly dry. Also please keep in mind that I don't have the car in my presence most of the time (I usually have to call in to the girlfriend to get information from her).

1. find your chassis number (can be found in the front windscreen at the lower corner)...

I'm trying to determine the chassis number and from your description of the location, it sounds like you're talking about the VIN number? Are they one in the same? Does the Chassis Number have to be decoded out of the VIN? (I've used the decoder here but none of the outputs label themselves as such and being as I don't have a sample output of what a proper Chassis Number looks like, I'm not sure what I should be looking for.) Finally, when looking at the PET pages, where should I be looking for the Chassis Number (Again, I think if I had a valid Chassis Number to lookup, it would be fairly obvious, but I don't.) I'm guessing, though, that the Chassis Number should be matched to the additional values in the "Description" field (i.e. F>>996S7 43975)?

...Having checked the online parts catalogue there is no differentiation on the 997 for 2wd and 4WD drive vehicles as far as options for the PCM DVD navigation. Of the four part numbers listed , one has the prefix letter A ( 997 642 135 03) suggesting its been superceeded and that a later part is compatable. Part number 997 642 135 04 is for an early PCM 2.1 (suitable for Cayenne Boxster and 997) and does not have the extended navigation capability , though this is not essential. 997 642 137 02 is for 997 , and Cayenne / Boxster models that were made after 2006 and does have extended navigation. 997 642 157 00 is the latest part number and has a prefix N suggesting its a new addition , it is also common to the GT3 and is shown in the GT2 catalogue as horizontally mounted.

The only vertically mounted DVD drive i can see is 997 642 159 00 this is shown in the GT3 parts catalogue (GT3 uses the 4wd chassis) and the Turbo catalogue. I suggest that if you plan to install the DVD drive vertically you need this part....

The PET I'm looking at (https://techinfo.porsche.com/techinfo/pdf/e...USA_KATALOG.pdf) only lists two possible vertical drive options (Illustration 911-01, Item 3) and neither of them (997 642 139 02 and 997 642 159 01) reasonably match the part numbers your listing so I'm rather confused... The Porsche retrofit instructions list 997 642 139 02 as the vertical part needed which does appear as one of the two numbers I listed above. Obviously being able to determine my Chassis Number would help me determine between these two, but now I need to understand where Berty's part numbers are coming from and how they compare to them...

Thanks everyone for all your help thus far. It's really appreciated.

PET for the 997 lists no fewer than 4 different part numbers for the DVD drive. Numbers listed in order are 997 642 139 02 , 997 642 159 00 and 997 642 257 02 and 997 642 257 03. Model numbers on the last two are the same I 615. For the first two the three model numbers listed are the same for both and are I 664, I 670 and I 674 for. In the schematic it's shown as being mounted vertically . While the numbers for the horizontal unit are different I can see no visual difference in the two and given that unit are both self feeding (you start the disc into the drive and the drive pulls it in) a doubt that mechanically they are any different. Interestingly, two of the three model numbers shown for the horizonally mounted units are I 670 and I 672. With that information overload I'm afraid having all those numbers won't help you much. However, if it were me, I'd install the one you have, so long as it matches one of the numbers above. If it doesn't match I'm afraid you're back to square one.

I'm still fumbling through the different cross reference materials a bit, but I think you might be looking at a 997-2 PET listing? The reason I think this is that the PET listing I'm looking at from Porsche.com (for an 07 997, illustration 911-01, Update 203, from 08/28/2006...granted mine's an 08) lists different option codes than you have and indicates the first two part numbers are I099 (right-hand drive). The other interesting thing is that the next two part nunbers you list aren't in the PET available on the Porsche site at all, but they do show up in AutoAtlanta's PET diagrams (but with a price half what the first two part numbers list at which makes me think they might be the DVDs themselves and not the drives?).

Here's another pic of the NAV & CD Changer inside a C4.

I suspect the wiring is routed behind the carpet and trim.

Ah yes that one is much better than mine :) Meant to get over to the local P-car dealer today but it didn't happen. Perhaps tomorrow.

JRagan,

Have you had an opportunity to look at a factory installed NAV & CD Changer in a C4S 997.1?

You might just want visit your dealership and see if there is one on the sales lot or in for service.

It might shed more light and certainly give you a 'visual' of what the finished job should look like.

Good Luck!

ps. I think it's already been discussed but I'm sure the fiber optic cable(s) as well as the power harness(s) are longer due to the mounting location.

Great advice :) I had actually searched the interwebs for 'for sale' C4(S)s with OEM changer and navigation in the hopes they'd have photos of the bonnet, and came up with this which matches the info I've been reading. In this picture you can clearly see the BOSE AMP hump + Attached Navigation DVD drive hump against the rear, and the CD Changer along the passenger-side fender. What I would LOVE to see though is the part number on the Navigation DVD drive...something I've yet to discern.

Got a response back from Suncoast, and they state that the included 997-642-157-01 is correct for the C4(S) and will work vertically. So I guess I'll go with it :)
