I have just updated to the latest version, and the update went very well. Easy to follow instruction on Fiat's website for Blue&Me.
Have tested the functonslity and it is very easy to use. Some problem when I use the "Call" function, but that might be because my pronounce of name is a bit different then standard English. But the phonebookfuture is working, so I use that.
I have an iPhone 5 and it syncs without problem.
I have also installed EcoDrive, and this I will tell more about later. Just some more testing to do.
