Garmin i3, why does it ignore motorways?

Simulation took me up the A4? Can anyone else have a go please.

AA.com Route Planner also routes you via the A4 and not on any motorways.

Multimap.com also sends you via A Roads (A37) and not via any Motorways.

So does GoogleEarth.

Maybe the A roads are the fastest / shortest routes?

Probably differences in the way the software calculates the route. Also if one map is slightly more out of date than the other then that might also account for it.

Maybe if somebody still has v7 maps they could confirm what route their i3 takes - you don't need to wait for a simulation to complete, you can just turn off the gps, set a start point, set an end point, and review turns.

My unit does have V8 software. Also the updates from the Maffs site.

For example if i plot a route from Sutton, Greater London to Durham the i3 sends me A3, M25, M1, M18, A1(M) but other route planners stay on the M1 longer to the A1(M) and skip the M18 section, some don't.

It's just differences in the software and maps. The differences between the journey times won't be that different. As long as it gets you there (and it's not going via some ridiculous route like Norway) i can't see the problem.

by the way dixie, the a4 runs east to west so how did the i3 take you on this road when you routed shepton mallet to tamworth which is south to north?
