So I'm looking at getting a vehicle and I saw two really nice 330's, one is about 980 more but has a factory in-dash navigation system. It seems like a good deal.. Is it? 980 more? I mean the cars are identical except for that the one without the nav has about 8,000 less miles but other then that they are the exact same car.. So should I pay the extra and get the nav system? Also I'll give best to whoever can include what all the nav does like can it play DVDs make calls, etc.

Useless, buy a Garmin.
