My one xl has stopped giving out any sound at all. It started by giving croaky voice commands{Jane} and then deteriated to breakup of voice ,then to no sound at all.I do not get the drum roll on start up or any warning sound either.I have done a soft reset and a reinstall using TT Home but still got the problem.I am using a 2GB memory card in the unit with western europe.I allso use another 2GB mem card with western europe and eastern block,no sound with either mem card. Guidence please as this unit is out of legacy ie no support from TomTom by phone etc.
