"What do I need to connect my TomTom device to my computer?
Every TomTom device comes with a USB cable in the box. Just connect your TomTom GPS device to your computer with the cable. You will need to have TomTom HOME installed on your computer first,"
Your post did not tell us if you followed TomTom's instructions.
I have a Dell Inspiron laptop with Windows 7 installed. I tried to hook up my TomTom 700 using the USB cord that came with it, in order to get new map updates and other information. But when I connected it to my laptop nothing came up on the computer screen. Nothing. It is suppose to ask me "if I want to connect" or something like that. Now, this is one of the first TomToms and it is about 5 or 6 years old but it navigates just fine. I could not reach TomTom help on the phone, so maybe someone knows what I can do. thanks! P.S. My laptop is only a few months old.
