Anymore input, I bought the avn 6620 yesterday. I read some reviews and canceled the order. Bought the Iva-w505 last night, read some reviews, now second guessing this purchase, lolllllllllll **** I'm indecisive. Help, please. Avn6620 comes with warranty from eclipse can purchase @ crutchfeld. Iva-w505, no waranty, purchased from a forum member. Help!! Oh yeah and what about the Z2, is that worth my time?
