Signal not working in mercedes, works in ford pickup
Yes, If your device cannot acquire a signal when mounted on the windscreen, this may be because your car has Heat Reflective Shielding on the glass. This can block GPS signals from reaching your device, to solve this you may need to purchase an additional aerial.

Look up Tom Tom directly on the Internet and download the latest Tom Tom "Home" program. Make sure the Tom Tom you are using is the one that was originally set up to your account. If you have bought a new Tom Tom, it wont work until you have registered the new device. I had the same problem. I replaced an old Tom Tom with a new one and my old account wouldn't work as it kept saying the devices were not the same and that my email details were already in use for another unit.. I had to email Tom Tom to correct the account details.

How to use tomtom properly
Make sure it is charged and when you let it run, make sure you can see the sky. The receiver in the TomTom should have direct contact with at least 5 or 6 satellites. When you are in buildings, or to close to high buildings, it could be the TomTon will notice.
Give it about 2 minutes to find its location, when you switch it on in a place where you did not switch it of. It needs more time to find and calculate where it is when you brought is somewhere else after switching off.
