Dartford Tunnel HD Traffic

swash · Regular Visitor Joined: May 22, 2009 Posts: 65

With my GO 540 currently unusable and Tom Tom offering their usual high level of support, I have managed to scrounge a GO 550 off a mate who is about to go on holiday.

My daily commute takes me through the Dartord Tunnel and with the 550, I have noticed that the blue HD Traffic Bar disappears when going through the tunnel and does not return unless the unit is reset.

I can understand that the unit cannot receive information whilst in the tunnel, but why on earth does the whole HD Traffic cease to function.

Has anyone else had this problem?

My Go940 on V9.026 software for the 950 did that and as you said it has to be reset or in and out of flight mode to restore traffic to get Live Services back. This was compounded by the fact that everytime the TT server did not respond, which was very frequent last Autumn, the same thing happened, several times per hour.

I assumed this was as I was using software intended for a different device and reverted back to V8 and the problem went away. Maybe this is a bug in V9 software, but the V9 for 940 does not work with Live Services at all so I have not been able to test this out. It could be a version specific issue such as 9.026 or earlier.

I too commute through the DT and I get the same thing on my 950 LIVE.

It seems to be that where on v.8xx the traffic bar went grey if it cannot connect for up to two of the three minute updates, now on v.9xx it just disappears until a successful update is received.

Definitely a retrograde step as any information, even slightly out of date, is better than no information. In the case of the Dartford Tunnel, every day I come out on the north side and have about a minute to decide whether to go off at J31, J30 or J29 and the traffic view almost never returns in that time.

Apart from the nasty inconvenience of having to get it working again, I don't see what the problem is. Surely HD Traffic is telling you the traffic situation before, inside and after the tunnel, all the way until you enter it, so surely any diversion decision must already have been taken (e.g. if you have only one minute to exit the motorway) and is unlikely to be affected by any changes during the time you're underground? How many minutes does it "normally" take to get through the tunnel and how many updates are you missing during that time?

What happens is that as soon as the signal is lost in the tunnel, all the traffic data that was there disappears and the traffic shows that all routes are clear so the unit tells you to carry on the M25. You would have to look at the traffic before entering the tunnel and make your decision there, not a difficult thing to do. Sometimes the traffic is changing that fast you would like an update before deciding to stay on the M25, especially if you are crawling through the tunnel in stop-start traffic.

When I had the 9.xx software on the Go940, the above problem happened. Reverting to the 8.371, the traffic information remains (not sure for how long) when the signal is lost, it just does not update.

I always choose the left bore of the tunnel so that at the last minute in queueing traffic I can exit for the A13 towards the North Circular without having to cross stationary lanes, if the M25 is congested, which it very often is with the road widening taking place at the NE quadrant at the moment.

Looking back, I think my post could be interpreted as less sympathetic than you really deserve. I apologise. I didn't think it would be much of a problem apart from the inconvenience and probable difficulty whilst mobile, of getting it back up and running. However, you do have every right to feel aggrieved if the program isn't working to give you what you expect from it (especially if it's another of those cases where the new is worse than the old).

I wonder if the day will ever come when TT issue a new release Navcore which doesn't somehow jigger something or other up for some users? So much of their updates seem to be blind firefighting trying to cure something they just don't understand any longer - where the heck are the original programmers?

If it's true it could explain simplified menus and no software updates for older models, and perhaps other reduced services. Instead of blaming TT, it seems we should blame Microsoft, and the technical developments at TT are presumably at the direction of their lawyers. You might also think that with the GO1000 using a web-based Home, there is tighter control of functions so that TT is not sued again?

This issue seems to have gone away recently with my 950 holding the data all the way through the tunnel

To Tom Tom couldn't have listened and actually gone and fixed something could they?

Amazingly it seems so. Smile

It does appear so! I went through the Dartford Tunnel this morning and my traffic bar remained in place before, during and after.

It seems that TT might now have successfully restored two of the features that have been "lost" over the recent years...

I spoke too soon!

Traffic bar disaappeared this morning halfway through the Blackwall Tunnel so when I came out the other side I had no idea whether to use the A12 or consider the A13...

It reappeared at the next three-minute update but by then I was a couple of miles up the road.
