Just downloaded it, not installed yet ….. you aren’t selling it to me at allIve had some stereo issues with 4.5 (sometimes will totally or partially mute (or distortion with static) with a change of state (i.e. use a turn signal; engage backup camera; putting the car in park; Homelink signal sent to garage door…not often, but sometimes)).
I also find the cameras very laggy now, and the moving map display is also slower to respond to changes in direction and/or zoom state.
My tire pressure pictogram has disappeared, regardless of resets or software reinstalling. I’m being told I may have to try a factory reset…
All since 4.5 was installed a week ago.
