See other posts but 6.3 has nothing to do with the M6 toll display or lack of.
On CN Europe 6.0 the road is shown but has the attributes of a track and the south end is incomplete. Because of its attributes the PC or GPSR will be unlikely to try and use it when the routing settings are set to "fastest". The GPSR will recognise it when you're on it but the time to next waypoint is all up the spout.
When the display shows the 8 mile map resolution, service station icons appear, when the resolution increases to 5 miles they dissapear never to return. Can I make them stay on the display at the higher resoloutions as it is quite handy sometimes to have them there without having to invoke a search for the nearest etc.
Although auto routing directed me along the non toll road and didn't show the new toll road once I was on it it recognised that i was on the toll road.
