Poor navigation in Devon

SouthHams · Posted: Mon Jan 23, 2006 7:35 pm Post subject: Poor navigation in Devon

After driving around now for a few weeks with my Navteq maps I find that the road choices are very poor and at times are likely to cause vehicle damage.

For example, when driving in the South hams between Lodiswell and Kingsbridge on a minor A road the route diverts from the road down a very steep un-made road.

Looking at the displays there seems to be no distinction between roads, except for Motorways and A roads.

This is in sharp contrast with the TeleAtlas maps on my TomTom ONE, which almost always finds the routes a local would choose.

Has anyone else had this experience?

I use Garmin CitySelect Maps which are based on NavTeq maps.

This is a known problem:-

I use a Garmin iQue 3600 with CitySelect Europe v7. [January 2005] I enclose two PC screenshots of software on the PC. [Settings-fastest route rather than shortest and ‘main roads’] .

One is with Truck selected.

The other is with Car selected.

If you need other screenshots let me know.

I use a Garmin C320. On my C320 I have an option to avoid "unpaved roads". Do you have this option.

I have also found with Navteq, setting the routing logic to fastest rather than shortest helps avoid un-made roads.

Try setting to fastest route, truck and see what happens. Try it again with car.

Just to let you know on your system the Routing Algorithm is not supplied by NAVTEQ. This is a VDO product. The Maps are from NAVTEQ but how VDO chose to use them is not down to NAVTEQ.

to be hinest in testing the non factory fitted devices do tend to route better than vdo etc

we have one truck with a vdo daytona systerm and even copilot 5 and 6 produce better routes and tomtom knocks spots off it

Southams says the unsurfaced road is rated the same as a B road, so this is a mapping error? Should he report it to Navteq?

To be fair to Navteq, I am sure road classification errors do happen, human error perhaps.

Have you checked the road on an OS map? There are a few roads in the Cotswolds near me that my Garmin i3 takes me that are classified as normal roads on road and OS maps but when you get to them they say "Not suitable for motor vehicles".
