Update done. Good news, no bricking, took about 15 minutes or so.
Bad news, issues still there.
While listening to Sirius, I can only skip tracks using the touchscreen. Using the steering wheel controls will drop connectivity and I have to change stations. And this is only when listening to Sirius. BT or my usb stick, no problems skipping with the wheel controls. The other issues, only time will tell…dropping AA, even while plugged in, losing phone connectivity, losing usb or Sirius connection and it automatically reverts to FM radio.
At this point, not even sure if it is the UConnect or something else entirely different. Oh well.
At least I’m up to date. Messed with a bit and don’t see any real difference from 39.7, audio quality or functionality wise.
