Two answers.
First obtain the owner's manual for your radio. MANY modern radios have a jack, often on the back, and USUALLY it is a special jack where you can plug in all sorts of things.. For example on my Pioneer I have a "LINE IN" adapter.. WOrks well so long as I'm not using battery power to keep my phone charged (Ground loop issues) And I can break the ground loop if I send Bob Heil some money. (He sells the stuff I need to break the loop.. His business in fact is audio stuff).
you may be able to get an adapter to plug in what you want. My options include Satellite radio receivers. THe LINE IN adapter. Multi-Cd changers and more.

www.crutchfield.com is just about the largest on-line Car Audio store period (And other audio) THere is one other that comes close (JR music???) but I'd go with Crutchfield.
The radios used in cars and trucks are all "Standard size" now days. DIN, Double DIN or triple DIN (DIN is the initials of I think the German Standard's Institute. Checked it. it is) SO as long as you are replacing a X-DIN with the same X it will fit.
Cable connections may be different but Crutchfield has a page of adapters darn near anything you have to anything they sell so again get the radio you want. the adapter for your ride and it's plug and play.
Finally one other recommendations.. Though I know these folks I have no financial or legal connection to 'em other than "Customer"

I have two of their CD's.. Unbroken (latest CD) and "On a Morning Like This" (Christmas) Blue grass group. and so far even people who are not all that thrilled by Blue Grass find this family (yes they are a family) of musicians... Worth the cost of a CD or 2. (NOTE that I'm not all that hot on blue grass myself. but these folks are G*O*O*D!!!!!!!!!!!!)
They have sample tracks.
