I have 3.0.2 and I'm pretty happy with my MFT Nav
MFT has it's climate command quirks and sometimes my ipod but Nav has worked flawlessly for the 2200 miles and 1 month I've been using it.
I will be doing the update soon to see if it improves the other things however.
Go for the nav, have it all together in one place and it looks a lot cleaner
