When I joined the forum half a year ago I asked about SW upgrades for the Navi as it was acting a bit strange cutting the music 2-3 times before giving the instructions.

I was at the dealer doing my 20000km service yesterday and they indeed had a SW upgrade for that and some other problems. My car is a TT built for Europe (Sweden) in May 2001. This might then not apply to US cars but I just wanted to pass the information on. After the upgrade the Navi has worked fine.

I also changed the plugs just to have everything ready for the wounderful summer season ...

 

I know for PCM II they have several updates here in the US....
