Re previous discussions I have bought new Tomtom 2.4A charger & USB cable but Tomtom will still not charge when plugged into either my modern or classic cars. It charges ok if I plug it into a USB port in the house. So presumably it is something wrong with the Tomtom satnav unit itself. Has anyone else had this problem. I bought it from Halfords just over one year ago so presumably no longer under warranty. Any help appreciated.
