If I want XM radio, do I just roll up to the dealership and tell them I want it? I won't have to buy any extra equipment, right? I'm assuming the XM will work on my facotry installed stereo and I just have to hit the SAT button.

Atleast, that's what I'm assuming...

 

yeah, you'll need the tuner kit. If you goto TRDSparks.com, you might be able to get it cheaper, then get it installed by your stealership.

 

I haven't checked into it yet, but do you know how much the dealer is charging for those?

 

$319 for the parts, $499 installed.

From TRDSparks.com you can get the parts for $275, and 1 year of free service.
