I feel that while most of the 3.5.1 upgrade is pretty good, Navigation specifically is horrible now. MFT routinely has trouble understanding what I am asking for, and it seems to be far more picky about asking in a very specific way. It's gotten so frustrating that I just don't even use it now.
What frustrates me most though is that I hear that MFT/Sync accounts for 80% of warranty claims at Ford Dealerships, and yet Ford hasn't said a word about the issues.
