APR05 Nav disks

[shopper]

I placed a friends APR05 Nav disks into my 987 which uses Oct04 disks. when I go to the Nav option it says the Nav software is incompatible albeit it all works apart from this message and entering the post code into the town field.

Any ideas on what I need to do to the PCM to get it to accept these disks.

(As I entered the disk it said loading for a while an then success, however I still get the message above).

From a June 22nd, 2005 Sales Bulletin:

Sales bulletin #79, published May 9, 2005, announced factory installation of Navigation discs. Factory installation was phased in as the standard installation method, as of mid-April Production. In 987 and 997 models with Navigation, the DVD is located in the front trunk, inside the plastic bag of vehicle components. In Cayenne models, it is located in the center console lower compartment. If you receive a new vehicle with a production date of mid-April or later, and that vehicle does not have a DVD navigation disc in the vehicle, do not install a NAVTEQ supplied disc before verifying the software version. The latest software version is notcompatible with previous versions.

Instructions for identifying Software

1. Press the PCM Main and Trip buttons simultaneously.

2. Allow system to recognize installed components (several seconds)

3. Highlight “PCM” and press the button to identify software version.

4. In “actual,” versions 04035xxx and 04202xxx use NAVTEQ DVD’s.

5. Version 05024xxx uses Porsche supplied DVD’s.

Your service department may also utilize the PIWIS tester to identify the PCM 2.1 software generation.

The latest generation PCM software utilizes map disc version 04.2005 or later, which is identified on the disc. These discs are installed at the factory, and additional copies will be available through your Porsche parts department. NAVTEQ does not supply these discs.

NAVTEQ will continue to supply map discs for vehicles with PCM Navigation systems prior to mid-April 2005. For your convenience, an updated NAVTEQ order form follows this bulletin. If you have placed an order June 15 or later, and did not receive a DVD, please resubmit using the updated NAVTEQ order form.

Excellent many thanks for this, I had no idea about this hidden menu. Any idea how you actually get the system recognise the software for the right disk as these options seem to be read only.

Looks to me like there was a major software revision and that you may not be able to upgrade. If it can be be upgraded then I am sure it can only be done with a dealer PIWIS tester.
