How can i tell what GPS tomtom one model I have?

I bought a used GPS tomtom one from my friend but i am not sure how to tell if it is a 3rd generation, second generation, or any other type? Is there a way to tell because the under side just says one.|||look for a product id on it somewhere and then google it.
