Ugrading my Pioneer AVIC N3...suggestions?
 

Hey guys its been a long time coming but i think its about time to upgrade my deck, i am currently running a pioneer AVIC N3 and ive changed EVERY part of my system numerous times except the deck. Anyone know of a new in-dash that is:
- single DIN with removeable face
- pref 7" screen
- must have navigation
- some form of semi decent EQ
- need proper ipod compatability
- hopefully a proper navigation that doesnt cut out when i go downtown(several kenwood ubnits my friends have cut out ALOTTTT)

Im not too concerned with the output voltage as it will be running into my bitone.1, also why the EQ isnt vitally important. I would love a deck that has tri-zone so if i install some rear-seat monitors i can display different things. It would also be cool to have aux inputs so i can connect my PS2/PS3 to it in the summer. Budget im not sure about yet, it can be new/used it doesnt matter, but im guessing somewhere in the 700 range? whatever you think my deck can be sold for plus a couple hundred, as usual is there is an exceptional H/U i will save up and try to buy that but im looking for a step in the right direction. I was considering the Avic N4/5 but using those stupid navigation discs gets REALLY REALLY ANNOYING LOL thanks alot guys
