Thanks for the speedy reply. It isn't really a big problem, just wondered why it wasn't showing me on the road 100%. Its only noticeable if I have it zoomed right in, or a notch out. Oh well, guess I can live with it. Strange thing is, I only noticed this after fitting new car battery. Is there a way to reset the gps?
Can't remember how, but there is a method via the normal menu structure to reset your position via the jog wheel.
What I would do first though is pull up in a straight side road and get it to show you your position. It should show you what number of that road it thinks your outside. Do this for both North/South and East/West roads to assess the problem direction. In my case it's only 1 house out, when I'm home (No 5) it tells me I'm at No 3. Close enough for me.
