I thought as much re the overspeed warning.

As for speedcams, I just downloaded the gpi file (from the sppedcam section of this site) here :- [Only registered and activated users can see links. ].

Then unrar and copy and past to the POI folder on the sd card. Is there some trick to this too!?

Its no real biggie anyway, as I use garmin mainly for off road, but I have noticed lately that its ETA's for routes, especially on long trips is a quantum amount better than primo.
