Road speed limit info

When I first bought my TomTom Go 510, it came with UK maps and the speed limit shown was pretty accurately e.g. when going from 30 to 40 etc. Is this information limited to just motorways in the western European maps (due to the size of the database?) ?

I much preferred it when it was showing all the speed limits. (I got slated by the OH when TomTom took us down some windy roads in Cornwall which were probably longer once we knew how to avoid these, so I assume speed limit info would produce better routes)

Hi sweepdog. It's not just the motorways which have their road speeds showing on the european maps. Most of the roads near me in Spain have speeds associated with them (not necessarily the correct speeds though!). To display the max road speeds alter the settings in "Staus Bar Preferences" which is on page 4 of preference menu. Editing max road speeds is done via the "Map Corrections" icon in on the TT.

The Max Speed has to be set up in the Status Bar Menu. On the 1st page Select Speed, and on the 2nd page Select Show max speed next to speed.

Strange as it may seem, the speed indication has no bearing on the Route Calculation. There is a separate item, attached to the Map data, that holds the travel time for each section of road.

There seemed to be already a tick my "show max speed next to speed", so I unticked "speed" from the previous menu and ticked it again. I'll see how I get on when I go out in the car next

Not been out today, but I remember the speed area on motorways is shown as 70/70, but when I'm off the motorway, I just get my current speed. Does this mean something is missing (I assume to save space it has a global variable for motorway speed)

The speed area is shown as xx/xx on any road where the map has the speed limit. If the road speed is recorded in the TT map as 30, it'll show 28/30 when you're doing 28. There is no global assumption of any speed limit. It's either recorded on the map and shows, or not recorded and you don't get anything.

The availability of the road speed limit is very, very far from 100%. So far as I'm, aware, it's simply that TT haven't (yet?) got speed limit data for the roads which don't show it - I have not seen any indication that they are dropping those details as maps "progress". There are also some wrong details. So whilst this feature is handy, please do REMEMBER, it's you who are responsible for observing the speed limit, not the TomTom device.

Dennis - re speeds. yes of course it's the road, but it used to amaze me how accurate the info was when we went into a new zone and just wondered what's happened to it (even on the same route)

Hmm, you must be far more observant than I. I've not noticed any roads which used to have speed limits which don't now have them. I don't suppose you can tell us an example (I have some maps which are two and a half years old and could look to see if that's the case on them)?
