Im so happy now , after so many problems with my F700 ( came with the update already ) I send it back before 30 days for a full refund and now I just got the Z-3 . Im really happy with this unit no issues at all, ipod interface is really nice , bluetooth is working really nice , the navigation is better than the f series , the sound is unbelieved , dvd picture is really nice , overall the z-3 is the better than the f series by much , of course more expensive ( i paid 1500. for everything with a 5 year extended warranty . So if you havent decided yet go with the z3 this unit is the best o
