There’s only one small problem. Apparently, the Ca-Fi uses the double-DIN slot which according to ExtremeTech, isn’t too common in many US automobiles younger than 1990. Bummer. I’m not car audio tech, but I’m sure there is some other way to get this baby up and running when it launches Spring of 2012 in the UK.
