I have recently installed the these POI's on my Garmin Mobile XT software. it works great but i have noticed that it shows the camera on the wrong side of the road.
Some cameras can get you no matter what side of the road you are on. It is hard to tell which cameras can, and which can not, so the machine is erring on the safe side. To be safe, you should just slow down no matter which side of the road you think it is on.
Sometimes it will beaps and shows me the camera warning even if the camera is on the other side of the road.
Sometimes if i am travelling on the freeway, it will give me a warning beep and message even if the camera is on the street crossing the freeway.
Is this normal?
Yep, this is normal.
One thing I think most people don't realise is that even thought the GPS can tell what altitude you are at, with respect to proximity, vertical distance is not taken into account so, if you are traveling over a bridge that has a speed camera underneath, it will still give you a warning.
I have had this happen to me even though the 'camera' was in a tunnel considerably underneath me.
