If i was you I'd wait for the new pioneer thats coming out.. The current top of the line model AVH-P7500DVD has a 7" touch screen plays dvds.. Tv tuner and much more..now the new one is supposed to have some kind of perfrormance interface kinda like the G-tech or belltronics..i dunno what features it will have but it should be pretty cool ...

$4k is alot!!! i found the pioneer unit online for 1599.99 plus 400 for the JDM Console and you come out to $2000 plus shipping so i recommend you shop around..
Be careful tho there are shops out there that rip people off..theres a shop in my town that charges 650 just to wire in a head unit! which takes likes an hour lol how crazy is that?
