I installed a W200 in my F350 a few weeks ago. I love it! I got it for $799 from SavingLots.com, which seems to be a kick-a$$ price. I also installed the PAC TR-7 video bypass and the PAC SWI-ALP to hook it to my stock steering wheel radio controls. It all works perfectly. I also put in an XM tuner and the iPod cable, with my iPod in the glove compartment. Alpine's new FullSpeed iPod integration really works well. And it is *fast*. I have 4800 tracks on my iPod and I can navigate around to any song I want about 95% as quickly as doing it directly on the iPod. It was this new iPod integration that really sold me on the 2006 Alpines over any other head unit.
Now I'm just waiting on my PXA-H701, Germaniums, and Stealthbox to arrive next week. Those and my 3 Carver amps should leave me with a pretty nice sounding truck.
