Thanks for all the feedback. I originally addressed this issue with the local Porsche dealer in South Carolina and they said it was not the correct disk. I wanted to make sure I had all my facts correct before talking to them again. I will post the outcome once it is fixed.

Here are all the software versions and information from Navigation Disk:

Unit: PCM

Target: 05024ED1/4705

Actual: 05024ED1/4705

Entered: Yes

Found: Yes

Unit: Navigation System

Target: This line was blank

Actual: 00179412/5004

Entered: Yes

Found: Yes

The Navigation Disk has the following information printed on it:

The numbers on the left of the DVD are 04.05. The top number on the right side is 997.642.257.02 and the number below it is 7L5.919.859.AC.

Thanks again for all the assistance.

As per the PM you sent me and my reply , you press the MAIN and TRIP buttons on the PCM front panel at the same time. This displays a service menu with a software version on the top of the screen. Under the top banner will be displayed the components of your system such as PCM , SYSTEM, AMP , TEL , and NAVIGATION. You may not have all of these options on your car but the PCM SYSTEM and NAV software versions are the most important to understanding your problem. If you use the Right hand rotary knob to select each component and then press the knob to select , it will display a software version. These are the numbers that you need to write down and post back to the forum. After you have collected the information you can return to the normal menu by pressing any of the main menu buttons on the PCM. The service menu does not allow you to change anything, so its perfectly safe to navigate yourself. If you look at one of the other navigation threads on this forum there are posts including pictures of the screen displays you are likely to see.

Thanks for the detailed instructions. I am a little gun shy with the car since it is new and more importantly, it is the wife's car and she would kill me if I messed something up.

What software version is your PCM, this is allow us to tell you what version nav dvd you need.

Forgive me, but I am new to the Porsche world. How do I go about determining the software version of the of the PCM. Seems as though I remember something about pushing several buttons on the PCM, but I don't recall exactly.

Thanks,

Joe

I think I have a related problem. I recently bought an '06 911S and the navigation system isn't working. It says the DVD is not readable. The disk that came with the car has an 04.05 date printed on the left side of the disk. The local dealer said that this was not the correct disk. I would like a second opinion before I go down the path to get a correct disk. Any assistance would be greatly appreciated.

Thanks,

Joe

Thanks for the input. Hopefully others will offer more information.

My wife and I are considering buying a Porsche 993 and I have been reading a lot on the forums recently. I have gathered that these engines have two issues that I should be aware of-worn valve guides and issues with the SAI. I have some questions about both.

1. Worn valve guides: I know that I need to get a PPI before purchasing a car. Is there a way to tell how worn the valve guides are with a PPI? Will a compression test or leak down test give me an idea? Do these engines normally need a rebuild due to this issue at 50k miles, 70k miles, 90k miles? Can you generalize this way?

2. SAI: I live in SC where we do not have emissions testing. :D From what I understand, the 95 model does not throw a CEL if the SAI system becomes blocked. If this situation is not corrected, does it cause any engine damage? Is there any engine damage with the 96-98 models if the SAI system is clogged and engine not rebuilt? How difficult is it to keep this area clean with regular maintenance? I know there will be an annoying CEL.

Thanks for the any input, and sorry if I am not 100% clear on my understanding. I am still learning.
