Anyone have hands on experience with this unit? It's going for $500. They say it is supposed to be coming out with Nav, but nothing yet.

yeah actually very nice unit, ive heard the same thing about the nav add on as well but yet 2 see it anywhere, preferably i would go with a D series but for the price its a nice unit right off the bat only spending 500 and eventually if you dont have all the money at first adding on the nav, i work at circuit city and that unit was selling for 900 a few months ago
