I picked up my EOS 2012 and am waiting the for the SmartTop in the mail. I will be installing it Friday on mine. I'll let you know how it goes with pictures if you want.
Regd compatibility with the 2012, I read that it had certain issues, but I asked the SmartTop guys and they said it works fine. I'll post back when I finish my install and whether it works with the full text configuration.
Regd use, I dont think its really useful for operating the top while driving since it tops out at 44kmph (30mph). My reason for getting it is that I want to be able to close the top as I walk away from the car or open it as I walk towards it.
However, people with current experience might be able to give you a quicker answer.
P.S: Cost $290 shipped for me. If you want to keep the car for only 3, the smartop would still work for a New Eos (fingers crossed)
