Just wanted to chime in with an update and say that I'm absolutely loving 3.5.1. I tested out the bluetooth connectivity today with Pandora and IHeartRadio. Firstly, before MFT let me control anything (takes a few seconds once the MFT home screen pops up) it had already paired my phone, detected my iPod, etc. so that upon entering the entertainment quadrant I didn't have any preset highlight nonsense when the car detects a new source; they were already all there. It started on the source I left it on (in this case BT Audio) and upon playing music through my phone, it's updated the track/artist info correctly EVERYTIME, it used to stop updating the track/artist info and get stuck on whatever song it stopped at.
I believe my bluetooth call quality has improved as well, though as I said my car has never seemed to garner the complaints from the other end that many of you have had.
We're a huge step closer to where MFT should have been from the start.
Anyone with Nav and the updated SD card care to chime in on how Nav is doing?
