I got the 770 in a GPS bundle with Navicore 2007. The Nokia GPS has been great but seems to have a problem with the road I live on. In short, it places me around one/two metres to the left of the road. So on Navicore I was shown as driving through some fields!

Additionally, when parked up elsewhere, it placed me a few metres from where I was.

I know nothing about GPS units. Is this normal behaviour?
