the people in the office at go via told me it wouldn't work on the car bracket in my discovery, but it is working perfect, I go over at the bridge at least twice a day and don't have issues,
It did work when I held it by hand against the windscreen,also if you do hold it by hand and its around the wrong way it doesn't work. Mine did work when I had it sitting on the dashboard, as long as the clip groove was facing the right way
