We bought a Tom Tom portable GPS system for our trip to San Francisco. While I am quite confident with my ability to drive in San Francisco, Palo Alto eludes me as I have never driven in the area. Rather than risk getting lost, we decided that a GPS system would be best for all of our trips.
Tom works very well but he does get upset with my speeding. I am not speeding in my sense, I am moving with the traffic. Every few miles, he squeals a warning. I do appreciate Tom but he does take me on strange trips.
I guess he knows where he is going.
I can reprogram him but he does a fantastic job telling me where to turn and which way to move.
