I'd like swap my factory 04 single disc hu for another factory hu with sirius. Is it a simple swap or is there all kinds of modding and rigging to be done??
Also, I'm thinking about a factory sub, mainly bc its made to fit. Is the factory sub any good or should I go with an aftermarket sub???

 

Well I personally would go with aftermarket sub and headunit. But if you have the headunit the only thing that your going to be doing is finding a place to put the sirius antenna. With the sub it all depends on what kind of sound you want.

 

My friend has the factory sub and hates it.

I went with aftermarket head unit, sub and amp. Its 100 times better than the stock!

 

I have Factory Sirius. And Its not in the Head unit. Its a module below the head unit. mine is a 2007, so I dont know if they changed anything.

I would check the salvage yards.
