Are built in Sat Nav's worth it?

[Barbarella]

Many new cars have Sat Nav's these days, but some are optional. The basic ones seem to be £500 - £1000, with top of the range 'live traffic' ones costing up to £2500! Are they really worth that? Is not a Tom Tom or Garmin, or even a free smart phone one just as good?

Yes, well spotted. It's an optional extra at £995. I don't have to make my mind up yet as it can be fitted when the car is in. At first I did think I would just get a Tom Tom or a Garmin (like you have done) but the built in one is tempting, although I am not sure as I would rarely use it. Hence the post, I'm just not sure if they are worth the huge cost. If they are better then Tom Tom etc then maybe. I've never had one, so I don't know. I do have a very old Tom Tom, which I would upgrade if I went down that route.
