You're probably hooped for what you want...........

Even if you could get the puter to play through the radio, you would have to write your own software/drivers in order for the unit to control the puter. Unless you plan to put a tochsceen up front. But, ultimately, the end result this way will not be very satisfying. I've been down that road................

You could go with a my gig unit since the 04 durango runs a can bus, but then you're only getting a 20 gig drive. Even smaller than going withthe ipod option.

You best out there, for what you want, is probably "bellying up to the bar" and buying the Chrysler ipod adapter and a 160 gig ipod or so..................not cheap..................but it will integrate the ipod with the stock head unit seemlessly.

Like I said, that'll get pricy, but everything is pricey these days.
