your friend is a retard
you need an app to "kick start" your gps. I use tomtom and MIO by the way.
download this:

set it to com 4 then click open GPS it will find satellites in a little bit then open up TOMTOM and you are good to go.
this thread will help you more. READ IT! In the 2nd post in that thread there is a program that jump starts the GPS and starts TOMTOM at the same time.
