Hello, I'm french, so sorry for my bad english.
The fiat tipo firmware wasn't working on my 595. The last firmware for 500 is VP2R7_150_23.00.81.00, but it's impossible to find on internet.
So I updated my uconnect at my fiat dealership for free.
After, I used MultiEcuScan for the proxi configuration.
Now AndroidAuto works perfectly !
