I can't recommend TomTom. My wife and I are borderline fanatical about caring for the things we own as we hate having to buy something twice. With minimal use, the charging dock no longer provides a snug fit for the charger, so, without notice it'll just shut off in the middle of a trip because it unknowingly wasn't staying charged. I have no idea if Garmans tend to lose signal when in large cities, but ours does regularly. We just borrowed my in-law's TomTom for a trip this weekend and we ran into the same signal loss issues. We'll be going with a Garmin when we decide to purchase another.
