is there a cheap way to hook up an ipod or other mp3 player to the stock radio unit?
Depends on your definition of 'cheap'. The USASPEC PA15-TOY works great in my '02 with the 6 disc unit. The adapter has two inputs, one dedicate iPod and one pair of RCA which can be pigtailed to a headphone plug that I feed an XM receiver into.
The device can be had for about $120via Amazon.
speaking on the subject, how hard is it to install a new head by yourself?

Remember that if you get a wiring harness adapter, it plugs into the wiring that goes into the factory amp, not the wiring that comes out of the factory amp into the head unit. Found this out after I had put the whole thing back together and called Crutchfield customer service. Oops.
