I just did mine. It's version 3.2.2. It successfully installed, but the one issue I found is the climate control. The on-screen buttons will work the A/C, etc, but it doesn't show the temperature and it doesn't show the system is turned on. On the 4-squares it shows the "power button" even though it's on and running.
The outside temperature is showing next to the clock at the top now and the FM seems to keep the channel when I go from FM to Sirius and back to FM (it used to go to some random FM station before).
