hi everyone, i hope someone can help as im having no luck with tomtom. Had a one xl worked fine with a 8gb sd card. Had all my maps and updates on it, along with truck routes and bridge information. Had a few problems with power supply, battery wouldnt charge and now wont even power up. So bought a reconditioned one xl off amazon. Assigned it to my tomtom account and introduced it to my sd card. It wont except the card and keeps telling me to remove it. Ive tried a few things that the forum suggests, including telling the device to use sd card rather than internal storage, but it wont let me change. The one xl works ok without the sd card, but i really need the truck info as i use it for work. Any ideas please. Big dog
