PCM Fuse Number?

[widebodytarga]

My navigation system cant seem to acquire sattelites consistently so I want to reboot the PCM system by removing the fuse. I looked on the drivers footwell and saw the fusebox cover and diagram but I cant seem to figure out which fuse needs to be pulled for the PCM. Do any of you know which fuse number it is? Thanks.

My apologies for not being specific about the description of my car. Its a 2008 911 Targa 4.

Do you have the latest software updates from Porsche?

If so then just disconnect the power cables from the back of the unit for a few minutes. No need to disconnect the antennas.

How can you determine what version of the software is installed? I recently bought the car so I'm not sure about the age of the software currently installed.

I used the instructions but I could not locate the software version. I do know the map DVD is 10.2006. Does anyone know the fuse number I want to try to pull it.
