    996 Navigation System Upgrade instructions

    I just purchased a factory navigation upgrade for my 2004 996. Along with the map CD's, it contains an upgrade CD that states it is to be installed by the dealer only. This is usually BS intended to extract a fee for doing next to nothing, so my intention is to do it myself. Does anyone know what has to be done to install the upgrade CD? Are instructions available anywhere? Thanks!

    Re: 996 Navigation System Upgrade instructions

    I do not want to discourage you, but give it some thought to pass by the dealer...

    The above is based on my following experience, albeit with my 997. I had a fault message that my DVD could not be read. Discussed with the dealer, who said the fault lied with the DVD (which indeed was 5 years old and had some scratches) whilst I was convinced the fault lied elsewhere (with the reader). My car had the extended Porsche warranty, which does not cover the DVD. I bought a new DVD, which also requires a PCM update (only to be done by the dealer). They tried to update, the system blocked, so they needed to replace the entire PCM unit (convenient, as I had a clean screen and MP3) under warranty. Afterwards, the system worked for one week and they needed to replace the DVD reader as well (under warranty).

    Honestly, I don't know what happens if the car is out of warranty (which I suppose is the case for you) but if the update does not work, and the dealer tried to do the install, maybe they will replace something on their cost or so. If you try on your own, the risk is entirely for you...
