I installed this update myself (via the PDF) and I can safely say my concerns have been all fixed now!
Climate was "broken" from the previous update (3.2.2 I believe) and has come back to life now and work perfect.
All bluetooth calling was very messed up previously, with any version. After I installed this one I can perfectly hear and speak via the car now and it makes me happy.
I have yet to find any problems now with the MFT not working and I hope it stays that way! Just thought I would post something positive because I know the MFT gets a bad rap most of the time :)
Good luck with this new version!
