540 - "unable to find a route"

I had to visit a Post Office in a small village in Cornwall yesterday, for the first time. My new 540 found the place no problem, using the postcode.

When I went to leave, I tried to navigate to a POI, but it couldn't find a route. Tried navigate to Home, and to a local town centre, and got the same message.
I was parked in a layby outside the shop, and had a good signal. Drove for 100 yards, and it found a route no problem.

Never had this problem with my old 510.

Have a look at the roads around the shop where you started your journey using "Browse map".

Is there a tiny break in the road somewhere in the first 100 yards of the route that you took from the shop?

Is the route marked as "one way" (look for small arrows on the map) or "not driveable" (look for a dashed line on the map).

If this finds the problem try to use mapshare to correct it.

If this doesn't find the problem post back here with the co-ordinates of the shop where you started your journey and the version of the map that you are using. Someone with that map will usually be good enough to have a look at the problem on their device.

Can't see any errors in the map.

The co-ordinates are:

N 50.21237
W 5.11833

Map version 8.204

Entering those coordinates my 940 is quite happy to plan a route from that position, it is possible that when you were parked up in the car the unit thought you were "off road" and therefore couldn't plan a route, once you moved a short distance and reacquired the road (as far as the device thought) it would then plan the route - Mike

Just to split hairs, I often set a route while on the top of a hillside where the road is more than 2 or 3 miles away and it quite happily sets a route for me. TT shows a dotted red line to the nearst road from my location and keeps updating this point on the road as I drive towards it.

I have had the unable to plan route error once or twice on a One and 730, I just put it down to a glitch as a power cycle solved it on both occasions.

I have seen this once on my 940 when I selected the option "avoid all traffic".

Rathe than there being a problem with your starting point, it could be that it was that the particular POI you chose to route TO was well off-road.
Can you let us know what that was? (or you could try to recreate it with a demo route from your same starting point.).
