I bought the Nuvi 680 GPS receiver for my partner for his birthday. I thought it might make him find his way home from work a little quicker. The problem is, that thus takes absolutely ages to find satellites when it is first turned on.

This means that you have to sit and wait in your car forever before starting your journey. The satellite reception is poor in a lot of areas where I live, and it takes awhile for the gaget to register that I'm actually moving, and have oppps missed the turn.

Very good if you are in a pinch - easy to use, lightweight, and has nice display and a non-irritating voice....
