PCM 3.1 Upgrade CD

[le_gazman]

Hi all,

Mine is currently on V3.41 and not being able to input a full UK postcode is annoying me. Is going to an OPC the only way to get an upgrade or can I simply download the CD and upgrade it myself?

Once that’s done I’ll tackle getting the latest maps but want to do this but first.

I bought the car from Porsche Center West London but neither the PCM nor the maps are very up to date.
