I bought a 5200 GO about 6 months ago via Amazon. Recently the speed camera alerts stopped working. My updates were 'up to date'. I've tried everything and eventually did a complete unit reset. It's taken ages to get signed back into Tomtom and I downloaded My Drive app. When plugging in GO to my PC I'm told I don't need to plug in!! I think everything is updated OK and unit works OK BUT still no speed camera appear on maps? I've done a simulated drive where I know there is a camera but it doesn't show during trip.
