Some things that I was doing wrong:

* I was inside my house next to a window & thought I should have been getting a signal

* I turned my GPS on before starting TomTom & turning on Bluetooth. Things seem to go smoother if you start everything on the device first and then power up the GPS.

* TomTom will say "no device found" even after you turn the GPS on, until the GPS has finished the boot process, so be patient.

* If it continues to say "no device found", then you should check to make sure that the advice from others is followed, regarding the global GPS settings. Program port on mine is none, and so is the hardware port. I have left "Manage GPS Automatically" unchecked. At one point I did change the baud rate to 57000. I'm not sure if changing it to something else would no cause it to break.

TomTom is so cool on this that I find myself walking around the city just to watch it hehe
