I agree that most imported roads already have speeds attache to them. I recently downloaded my latest update to my Garmin and in my area 90% of the roads have speed limits included in them and they are very accurate
. It would be handy if in an future version it would be possible to toggle a speed alert when exceeding by a parametrable unit of MPH or KPH above permitted speed. We all live in different locations with different rules and different ways of implementing them. I have notice in a previous post that someone in his region can over speed by 10 to 15mph without any problem. Well is is not so in my region speed limits are enforced very radically and in certain zones the $$ penalty doubles by every 5 kmh. I have also seen in a previous post that it is the responsibilty of the driver to know in what zone he is and to go by the rule. I have often seen ten's of kilometer or miles without any signs, so if you miss the first one, I suppose you have to guess your speed limit.
As far as GPS speed not being accurate I disagree I often compare them to my car speedometer and most of the time they are within 2% of the car meter, but then again the car speedometer might be off.
And as it mentioned in previous post if you don't want it, just turn it off
approve of this recommendation. I am using it on my Garmin even thought they don't have the alert yet.
