PCM2.1 Upgrade / Update

[bayernstern]

Hello, I have a 2005 Cayenne S with PCM2.1

The PCM had SW Version 1.0 ( Standard Production ) at first. I used 000.043.205.47.003 and was able to successfully upgrade from SW Version 1.0 ( PCM software version 04035AD1/0304, Standard Production ) to SW Version 2.1 ( PCM software version 04202MD1/1805, upgrade version Model Level A ).

Then, I used 000.043.205.47.002 and successfully upgraded from SW Version 2.1 ( PCM software version 04202MD1/1805, upgrade version Model Level A ) to SW Version 3.1 ( PCM software version 05024BD1/1705, upgrade version Model Level B ). I also used 000.044.901.40 ( which is part of the latest and greatest 955.044.903.61 and I am using North America 2009 maps ).

Here's the question: how do I upgrade to Model Level C, Model Level C1? ( which seem to be the highest upgrade possible for PCM2.1 ) I thought that 955.044.903.61 would bring me up to the latest PCM software version and up to the latest maps... I do have the latest maps, but my PCM apparently was not updated all the way through ( it remains in SW Version 3.1, Model Level B )...

I'd be grateful for any assistance folks on here may be able to provide. Thanks in advance.

I have SW versions 3.3, e.g. model level B (PCM version 05024FD1/4805) in my PCM 2.1 unit (MY06) and no problem with the latest DVD - Navigation disc (08.2009 maps). New DVD navigation discs are supported from model level B, so I made an update of Navigation System module only.

Unfortunately, I have no evidence of any reason to update PCM 2.1 unit to model level C. Maybe newer PCM SW versions influence TMC functions, which should use PCM Radio module.

I suppose (am affraid of) that PCM 2.1 Multimedia update to model level C is available via authorised/dealer shops only due to some issues with previous updates. I found some people had to use repair kits for specific release of model level A and B updates (issues with CD and Bose amplifier module).

Guys i have a real head scratching issue that i would love to resolve.

I recently purchased a PCM2.1 BE 6654 (7L5.035.191H) unit from eBay as my unit which came with the car (Cayenne S 2005) was a PCM2.1 BE6663 (7L5.035.192A) and it had completely died beyond repair.

The new 6654 unit works perfectly well but there are two errors on the new device. One at start-up which says "amplifier not available" (even though i have sound) and one when i try and use the navigation system which says "Incompatible Navigation Software". The maps just hang on a single screen and are useless.

Are you able to assist with the above? As the new unit works it sounds as though i simply need to upgrade and update the software but this sounds like a confusing subject. If you can help out or provide me with any discs it would be greatly appreciated. For your further information, the software of the unit currently reads as follows:

Unit: Amplifier

Target: 00012118 / 3139

Actual: -------- / ---------

Entered: Yes

Found: No

Unit: CD Changer

Target: C32 / 2702

Actual: C38 / 3003

Entered: Yes

Found: Yes

Unit: Navigation System

Target: /

Actual: 00174412 / 4804

Entered: Yes

Found: Yes

Unit: Phone

Target: 0002.22R / 1803

Actual: 05034B54 / 0305

Entered: Yes

Found: Yes

Unit: System Software

Target: 03505AD1 / 5003

Actual: 03505AD1 / 5003

Entered: Yes

Found: Yes

Unit: PCM

Target: 04035AD1 / 0304

Actual: 04035AD1 / 0304

Entered: Yes

Found: Yes

Like i say, I am basically trying to resolve the amplifier error message (the amp works fine remember as i have perfect sound) and the navigation issue. My Cayenne has an external DVD drive which worked with the faulty BE 6663 so not too sure if i simply need a new DVD, or a CD to pop on the head unit.

Kind Regards and Many Thanks in advance for any assistance.

I would try to get a hold of the latest update disc (DVD) set (3 disc), one is an update disc for the PCM software (you put it in the PCM headunit), one is an update for the NAV drive unit (you put it in the NAV drive unit under the seat), and the other is just the new Nav maps DVD. If you are a contributing member on the list here you can go into the DIY section and download the Porsche TSB that has a step by step on updating the system. Without that you will probably have to take it to the dealer and have them do it. Probably only about 1/2~1hr of labour charged and the cost of the DVD discs.

[hahnmgh63]

Ok, I see from your other post today that your software version that the unit has level A software (04035) so you will need to update it to level B per TSB 3107 enu 9110.

How do you access the TSB's on this site?

I have heard that the firmware update from PCM2.1a to 2.1b people had issue if the PCM is equipped with the Bose system.  Has anyone successfully updated the firmware by following the instruction of the TSB for their vehicle with Bose?  Thanks.

[hahnmgh63]

Yes, I have upgraded two Bose systems from Level A to Level B. Just follow the TSB and make sure the vehicle is on a battery charger. Kind of impractical to just leave it idling as it take about a half hour if I remember right.

It is only on early Model Year 2005 987 and 997 cars which had problems updating Bose amplifiers. If the Amplifier software version is 0017500 or above, they are OK to update. Prior to that, there were 3 versions of the amp, and 2 of the 3 are bricked if you try to update them.  You can get round this by modifying the update CD to remove the amp update.

 

The Bose amps in Cayennes do not suffer from this problem, and can be safely updated.

[gchu]

Thank you for you guys' clarification before placing the order.

 

BTW, how am I able to check what version is my Bose Amp?

 

Last question, I was told the update CD P/N 000.043.205.47.002 is part of the PCM update kit.  Now the current release is 2015/2016 P/N 997-044-904-51.  My dealer told me that the update CD for 2.1a to 2.1b is not part of it.  Is that true?

 

[Richard Hamilton]

Generally, if you buy the map disks from a dealer they remove the update CDs which are supplied with it.  When I had my PCM2.1 I ordered the new map from an independent specialist, and it came in a sealed box with the update CDs included.

[gchu]

Thanks. Found a place who selling it with the update cd.

Hi Richard,

I checked the version of the Amplifier software of and found an exclamation mark next to the Amplifier (see images).  Should I have proceed the normal update or you mention there is an method to modify the update CD to bypass the Amp?  The version number is way lower than your suggested 0017500, but this is a Cayenne, not a 997.  Thanks.

There shouldn't be any problem updating your amp. The warning triangle might be caused by a fault, but I have seen lots of occasions where there are warning triangles and there are no operational problems with the system.  Sometimes they clear after updates, and sometimes by clearing the fault memory with a PIWIS.  

[gchu]

The Update DVD Kit arrived today.  Followed the TSB instruction and everything went smoothly well.  After that, the exclamation mark of the Amplifier is gone.  Tested everything and found no other issue.  Thank you for everyone that helped me on this.  My map has been updated from 2004 to 2015.

Hey Bayernstern and Gchu,

 

I have a Cayenne 2005 T that I’ve been trying to update to no avail.

SYS SW 03505AD1

AMP 00012118/3139

CD CHG C38/3003

NAV 00179126

 

I love this car but I can’t find the right info to update. What should I buy and where?

 

Thank you so much!

04035 means your system is at what Porsche call Standard Production Status.  You need to update it to Level A, then Level B, and finally Level C.  After doing that, you will need the latest map disk, because your old map disk won't run.  I can't advise where else to get the US map DVD, other than going to a dealer.  The disk might not be as expensive as you think, so it is worth asking.  As I said before, when I have bought map disks from Porsche, via my Porsche specialist, they have come complete with the update CDs.  I have heard that people (in the UK) buying them over the counter at a Porsche dealer come with the update disks removed.

[memomartin]

Thank you, I was looking online and somebody overseas was selling the update disks and the 2015 maps, but when I was going back and forth with the seller, he indicated that there could be some problems, so I didn't wanna risk it. I talked to Porsche here in Massachusetts and they said it was gonna run for like $600.

If anybody knows who sells them I'd really appreciate the lead.

Thank you again!

[Richard Hamilton]

Well, a quick Google took me to Suncoast Porsche at $255: https://www.suncoastparts.com/product/PCM21UPDATE.html

 

I'll PM you a couple of other options.

Here we are in 2023 and I'm having the same issue as @memomartin here in the states with my 04 Cayenne T. In addition the stereo doesn't remember any station settings or even appear to have maps as it comes on and says Maps not available, CD changer not available. Is there an internal battery that the stereo uses for memory or is it just not hooked up correctly after a previous owner tried to install an aftermarket system (he did and removed it).

It appears to be reset back to original default (12/08/03), and honestly and regretfully much of what you guys are printing here is Greek to me.

How do I find the PCM version I'm on? and where might we find some discs? My dealer is 1.5 hours drive from me in Atlanta. :o  THanks, all. @Richard Hamilton!

[Richard Hamilton]

I don't recall hearing about station presets not saving, and if the previous owner has altered the wiring and not returned it to standard, then we are shooting in the dark.  The 'maps unavailable' and 'cd changer unavailable' are likely due to a fault in the fibre optic circuit, but it is difficult to put a finger on it.  I think you need to get a Porsche specialist to check it out, but in my opinion you are likely to spend a lot of money trying to resurrect a 20 year old navigation system that was out of date before it was introduced.  Just my $0.02s worth.
