Posted: Sat Nov 18, 2006 3:14 pm Post subject: NUVI 310D AND TMC TRAFFIC WARNING PROBLEMS |
|
|
Whilst travelling from Wiltshire to Cannock in Staffordshire, the TMC on my GTM12 is good (signal level of 6 or 7 most of the way). When I have planned my route, it warns me of Traffic incidents that are not on my route - ie when I touch the red warning triangle on screen it shows an incident on the A34 whilst I am travelling on the M6 and then onto the A460 (I am nowhere near the A34.) I do this journey once a week and it is the same on each occasion.
Does anyone else have these issues? |

The A34 goes straight through Cannock (from the same roundabout the A460 meets the A5 just South of Cannock) - if you pass the end of some traffic (even if you are not going onto that road) or cross through some traffic the Nuvi will provide you information about it, in case the tailback affects you.
This link shows the A34 and Cannock
So, it would seem (to me) to be working correctly. |

Swing - I should have provided accurate information. The incident it shows up most of the time is at "weeping cross on the A34" and I come off the M6 at J11 and head to Cannock on the A460. As you rightly say, the A34 does go through Cannock, but the incident is 8.4 miles from Cannock, so should it still show this? HERE is the map
Edit once to sort out the link - don't worry about not getting it right, we have all (and still do) get this wrong from time to time - Mike Alder |

When it occurs, click on the line of traffic, and then click on the map button and it will show you exactly where it thinks the traffic starts and stops (and will show your route too), which may explain to you why it's appearing.
Either way, it still sounds fine to me (ie not broken), even though it still seems wrong to you. |
