Hi Guys,

It's another nav problem I'm afraid, I've recently upgraded my MKIII sat nav to MKIV from Bimmernav. With the MKIII I used to get an intermittent problem where the sat nav wasn't quite lined up with the car, ie. it would show me about 50 metres to one side of where I was. Then it would constantly try and 'snap' to the street it thought I was in, and then snap again when it realised it was wrong.

If I input my position manually by using the junction of two roads it would fix it for a couple of days, and then it would lose it again.

The thing is I've started getting it with my MKIV which suggests something like an antenna problem to me. It's just strange that it almost knows where I am, but not quite.

Sorry for the long message, if anyone can help I'd really appreciate it.

Simon.
