Speed indicator on Tom Tom Go 300

Hi ,
I have searched the forum and the web to find the answer to the above question. Unfortunately yet to find an answer.

I am trying to set up the TTG300 to indicate my traveling speed and the speed limit on the road (and perhaps a warning if I am speeding !)

1. Can the TTG300 measure my traveling speed (Velocity) ?
2. Is there a database which can be used to indicate speed on roads (similar to the camera POI database)
3. can the TTG300 be set to warn if I am speeding.

Many thanks in advance. 8O

1.Yes, it can measure and display your speed.

2.I don't think so, I have read on this site that teleatlas are working to add speed limits to map data but it would be some time before this appears on Tomtom and I can't see it being a free upgrade.

3.Once the data becomes available it would be easy for TT to allow warnings, but without the map-speed data it's a no at the moment. POI's aren't really much of an option since you would need one or more for every road. Not sure how many the TT could cope with; I suppose there could be a project to allow us to contribute to a free database, not sure if there's one running already.

There must be some sort fo speed data for each road in order for it to work out the ETA

Well just to add to my reply about TT adding speed limits to the map data it appears these won't be actual speed limits but a guess based on the road type and locality type. Here is what the article says on the subject:

Yes, I knowe we are going a bit off topic but I would like to see in England a similar system they use in Scotland; 3 or 4 sets of signs 100m apart, so it wil say 30 - 300m , 30 - 200m, 30-100m , 30 ! It's kind of hard to ignore that.

I've also been thinking how could a free database be coded? You could put the cords and road of each speed change and then you need to take into account the direction ie a speed change has a speed before it and a speed after it. I suppose if we could slowly build a database then we would need TT or third party developer to allow the TT to process this data. Once up and running though more people would hopefully want to contribute. A big project and what comes first the chicken or the egg??
