Ok I found an answer to the 5 button question - it has all the stuff one would expect in a DIC which the 3 button does not (crazy that would be an option)

Anyhow someone on eBay is selling the 5 button DIC with trim piece together for $288 - beyond what I want to pay. You can do it yourself buying the DIC for ~$80 but you then need to do some wire clipping and also cut holes in the dash for the 2 extra buttons.

Ill check my phone for temp
