I have been given a TomTom One series 3rd edition and wish to connect to my Mac (OSX Lion) for any updates. However upon connecting to my Mac for the first time nothing happens except for a notification icon "internal" on my desktop that it has mounted ok. I downloaded the MyTomTomSA application and I assume it is running in the background but nothing happens when I click it or connect my device. I assumed when I connect to my Mac it would start automatically but nothing activates. My TomTom is switched on and the first request on the TomTom is for me to wait presumably while it loads and then a screen shows a wired up graphic but then nothing. Am I doing something wrong or is there another step I need to complete to activate the update status? Can anyone help please?
