No Route Planned - Error?

juliaosborne · Posted: Mon Jul 13, 2009 10:10 pm Post subject: No Route Planned - Error?

I find that I get a not infrequent error on my Satnav - a TT One XL. It doesn't happen every time, but from time to time I will have done a journey away from home and it will have behaved faultlessly, I will then go to plan the jouney home - usually by the 'Navigate to' function. It will start to calculate and suddenly stop the process, announce 'No route planned' and return to the start again. Successive planning attempts, do not resolve things, neither does a power off and on, the only thing that fixes it is a needle and reset button. I have also found that the problem occurs regardless of whether I turn off the unit between trip legs or leave it running on battery whilst I'm at the meeting for example. The error doesn't occur on every trip, but crops up every so often when it is a pain in the neck. Also, sometimes my unit seems to have difficulty in switching off - could it sometimes get involved with processing things which means it can't switch off until it completes?

Has anyone else noticed these problems, and worked out what's wrong/what the fixes are please?

Apologies if the answer is already in the forum, but I've used the search function and can't find the 'no route planned' string in relation to this problem.

Julia,

Have a look at this thread, there are a few explanation of what could be happening.

Thanks Steveee

I worked through most of the scenarios in that thread and the problem has occured in many of them i.e., it's happened when I have not been on bonefide roads, but it is happy to navigate to the off road location on the outward journey which seems odd, I also have a slightly off road home location which might not help, also I have not been able to resolve the problem after driving to a road that it has previously recognised on the journey in, strangely it often improves after I have synched it with TT Home and done the mapshare thing so it could be connected with that. That thread seems to indicate that it could be no one thing, but it is useful to know that my unit is not alone with the problem - I began to wonder if I had a Friday afternoon made device. Laughing

Julia,

I have been building a POI database for a company I am running. The POIs provide locations of restaurants and hotels we are providing our service to.

One thing I quickly learnt is that if the location is not on a public road TT cannot calculate the route, e.g. the hotel is at the end of a long private drive. To overcome this I now position the POI on the nearest public road. You may have to do this for your home location. Cool

There is another TT quirk that was not mentioned in the link. Quite often TT fails to calculate a route to city centres as they are pedestrian precincts or have restricted access. For example, if you try and plan a route to Nottingham city centre you will get a "no route found" message.

Hope this helps. Very Happy

Thanks Steveee - I'll re-position the home location to the road outside, might as well have everything that's in my favour going for me. It's interesting about the city centres - I had noticed that. One day I planned a route between two city centres and it did throw up the error as you described. Maybe a sticky should be started - 'known quirks with unit X'!!

I thought I would revist my thread with an observation.

Despite sorting all the locations out so that they were on proper roads the TT unit still threw that error up on the odd location.

However, it hasn't done it since I took TT up on their new maps. I installed new maps and contrary to what I did before I took note of someone's signature line that I'd seen on here and since installing I haven't taken map-share updates from TT Home.

Now it may be coincidence, but I haven't had 'error during planning' since I updated the maps last October 2009. Whether this is a light-bulb moment Idea

or a coincidence, I don't know, but there might be something in it.
