I have a new Suzuki Vitara and it has a GPS system installed. It appears to be Garmin based. Suzuki have given instructions on how to add my own POIs. Using a CSV file I have now added safety camera locations. However I cannot see the safety cameras on the map like I can for the Suzuki installed POIs. I am not sure if the GPS is restricted to allow 'my POIs' to be added but cannot show them on the map. Do I have to add a bmp file somewhere in the file structure?
