My truck is an '07.5, the first year of the IBC, I believe. I had a Prodigy in my '04 Silverado as well. It was a good unit, but this one works just as well for me. It's easy to adjust and has proven to be reliable. Basically it's been a non-issue for me. I'd recommend giving it a try to see how you like it before installing the Prodigy. I would guess they've only gotten better over the several years between your truck and mine.
