I'm getting my install done on 07 Nissan Sentra next weekend, and am now wondering if I'll need to buy anything special to retain steering wheel controls or if they will all still work?
I'm assuming the bluetooth buttons won't work, but will volume, mode, and track up/down still function?
All of that will work with the PAC SWI-PS version 1.6.8.
EDIT:
Ok, so it looks like what you're saying is I *DO* have to buy another component to retain this functionality:

Correct?
Yes, but only with version 1.6.8. You need to be specific on that as many dealers may still have the previous version which will not give you the latest functions.
EDIT:
Ok, so obviously the 1.6.8 is the rev of the PAC model. How can I ensure that that is what I'm receiving and not an older one? On Amazon they don't carry that info. The PAC website shows the version that is latest is blue, but it's like $80 on their site. Is there a reliable site that carries the latest version at a decent price that you'd recommend?
You will need to call whoever you decide to order it from to make sure your getting the version needed.

The last time I checked this store indicated they always carry the latest version. I would call or email them to be sure though.

I bought mine from woofers etc. via ebay. $42.90 shipped and it arrived quickly. They clearly state that it's version 1.6.8 as well -
Thanks, Steve! I just bought it. And I had forgotten that I had a bit of a Paypal balance, so it was "free" to me. 
Another question: One installer I talked to mentioned I'd need an AM/FM tuner device? But I haven't seen any mention of one here or elsewhere. Again, I have a 2007 Nissan Sentra, is that something endemic to that model or is it not an issue at all?
The Z has an AM/FM tuner built in. Sounds like an installer that wasn't thinking straight. I don't know of any aftermarket stereo without an AM/FM tuner built in.

Actually what I think he was referring to was probably an FM antenna adapter. You will likely need one of those for your vehicle.

Basically something like this I'm assuming?

Or is it something even more basic like this $10 one:
I have a SWI-PS REV 1.4.6 Anyone know if this will work on the Z110BT in a 2010 Honda Odessy??
It will work but will not support the handsfree or the voice recognition features of the Z110BT. As mentioned on here, you will need version 1.6.8 if you want to access those features with your steering controls.
