Well, I've put 1,000 miles on my truck and the only time I've touched the steering wheel audio controls is accidental bumping.
I'm upgrading my head unit this month and don't think it's worth the $50+ that it seems to cost for the steering wheel control adapter. I won't miss them, but I also don't want buttons that don't connect to anything.
I assume that the trim levels that don't include steering wheel audio controls have the same wheel, but with a blank where the controls are. I'd like one, but can't seem to find any information about it.
