Best route for 05 Sirius install...?

[Texas F-150]

Well guys, I always feel like I'm taking more information than I'm giving around here, but you're all full of such good knowledge.

Anyhow, I've got an 05 with the premium sound (i.e. 6 disc, steering controls, etc.) that I want to put Sirius into, because I'm moving to BFE. Whats my best option if I want to retain a factory look and steering wheel controls? Will an 08 unit drop in, and if so what is required?

Thanks in advance for the great help.
