My CS came without it, and I was always curious. I had a chance to test it out when a loaner from the dealer had it. I was not impressed. The idea is that you're supposed to be able to operate the radio and PCM without taking your eyes off the road, but you can't do that with this wheel, largely due to the PCM interface. For example, you can use the scroll button on the steering wheel, but you still have to look at the PCM display to see what you've scrolled to. It actually makes it a bit more awkward to be using a button in one place (the wheel) while looking in another (the PCM display). It's easier to use your right hand on the PCM buttons while you are looking at the PCM. About the only thing that you could really use without taking your eyes off the road was the volume control.
On the other hand, this is with an '08 and PCM 2.1. You're talking a '10 with PCM 3.0. There could be a difference.
I was looking at this as a Christmas present to myself from the family this year....
I saw the option here in the UK is about £380. So I thought it won't be that bad.....the dealer then goes on to tell me that it's more like £1000 to retro-fit a multi-function wheel. About £750 for the wheel and the rest in labour. So its not on my Christmas list anymore!
Moral of the story - if you are getting a new car - get the wheel at the same time!
Definitely the options are cheaper when order with the car than retro fitted. Definitely get what you want in the first place. The cost for a steering wheel option at the time of order is nothing compared to any other cost.
I bought a used multi function wheel from e bay for 100 pounds, fitted it myself (moved the electronics over to my existing wheel) and had it coded by my local OPC for an hours worth of tech time. Total cost about 220 pounds. As long as you already have a triangular airbag steering wheel the retro fit and install is straight forward. Takes about 2 hours maximum , an easy DIY mod if you have torx and spline tools.
