Yea, I like the double din ones, they look more like a factory fit.
How much are you asking for your KVT-815dvd and have you priced the DDX8019? I work at a stereo shop here. The DDX8019 is awesome, a guy that I work with has a white 08 xb2 and has the DDX8019, its basically just like the DDX7019, but is Excelon and has 5v pre outs, and a couple other extras.
My steering wheel controls work with my Kenwood DDX7019. I used an interface module from PAC http://www.pac-audio.com/products/pr...heel+Interface . The part# is SWI-JACK . As far as the IPOD/AUX goes, my Kenwood DDX7019 has ipod/aux cables on it. I haven't tried to see if I can make the factory Scion ones work yet.
And I think keeping steering wheel controls is sick. I wish I got the PAC adapter for mine, but I'll manage. I've been thinking about just keeping the stock H/U and using the RF 3sixty.2. I'd retain all the factory stuff and I'd have the full adjustability.
But no DVD.
I'm actually going to check around tonight for wiring stuff to see if I could wire the stock Ipod interface to an aftermarket one. Shouldn't be too hard.
