Hi, I have c-hr hybrid excel 9 months old and having problem with the speed warning. It is set to come on at 3 miles over the limit. If the voice does come on, and it doesn't always happen, I am doing 10 mph over the limit. I have just had software update and this has made no difference. It use to be quite accurate but not anymore. Please can anyone help. Dave.L

maybe a stupid question, - but you are aware the speedometer is showing 7-8% over actual gps speed ? let me explain what I have :
You have 2 options of warnings - in the 'center display' I have set it to warn at 5 km./h above the limit (as seen by the sign-scanner)
That will warn when I go 5 km./h above whatever it has seen , but as the speedometer is showing 7-8% MORE than actual gps speed, - it will actually trigger this warning just below, - or at the limit.

roadsigns says 80, - I am driving 85 on the speedometer but the actual GPS speed is 77-78, - and it will warn.

the gps however, is reacting to GPS speed, - so setting that to yell at 5 km/h above, - will cause the alert-speech 5 km/h above true gps speed.

so, - roadsign's says 80, - I am now doing 92 on the speedometer (already had the first warning bleeps from the center display at 85 on the speedometer), - and then I get the speech "the speed limit is 80.

So this is just to illustrate the different ways of measuring.
a 'speech warning' at 5 km./h above speed limit will not appear, in my above example, before I am doing 92 or something on the meeter. Way above as you say.

but the speech "the speed limit is..." is accurate in terms of true GPS speed + the limit you have set.

p.s. I have a true GPS meter/display in the car also.

sorry, - havent been here for a while, - and you might already have gotten other answers.. but yeah... if you set the warning at the legal limit, - it should warn you about 5 km/h _before_ you actually reach the legal limit (due to the speedometer showing 7-8% too much), - but you should check it.

your phone probably has navigation ? or find any speed/speedometer app... I also have a watch.. a bike computer and a couple of other things that will show true GPS speed :)

and it might be different for you due to tires and so on, - but in generel my car shows 7-8% too much on the meter in the car. So I am setting the warning at 5 km./h higher than the legal limit, - and according to all my devices with true GPS speed.. it will warn me when I hit the legal limit.

I did not know there was a voice, I just gets beeps if over. I always set mine to what the speedo reading is i.e. 30mph limit then I set it at 30 even though I have a separate gps on my car cam which actually shows 27mph. Oooops, sorry, my bad, just realised this is for the Sat-Nav, not the car itself! :oops:
