Just as a ps to the post above.
I'm pretty sure that the maps in my own car have been updated. A village not far from home has a new by-pass and, until fairly recently, when driving along the by-pass, the satnav map showed me driving well off road ! However, now when I use the by-pass, the new road layout is shown correctly.
I never really gave it a thought until just now reading this thread. So thanks for starting this
