Can anyone advise me on getting a replacement battery in Sydney please? I have tried numerous times with Tom Tom with no luck as they are based in UK and advised to send the whole GPS to Victoria or send links that don't work. They replaced the cable and it worked for a little while and now as soon as the GPS is disconnected from the car (even after a days driving) it indicates low or empty battery. Very frustrating when you need it for directions when travelling. So hard to get answers from Tom Tom!!!
