I have a 2011 XLT w 302a package. The screen was slow and the Blue tooth was horrible. As my wife did not use the blue tooth , i never noticed it till a few months ago i brought a tundra limited and she took it....
anyway, now i have the explorer i *****ed and complained about this crap on a 40k car.
the newest sync update is avialable, i downloaded to a flash drive and did an update on yesterday commute. 30 minutes .
i bet mine was never updated from the original.... the quick fix
1) The bluetooth phone clarity is crazy good as per my mom and wife. More media support. It can now play music from the bluetooth device via bluetooth.
2) The touch screen is very very responsive. No more touch, touch harder wonder if it read.More zones per doc.
3) When i put the car in reverse some color coding is coming on , not sure what this is.
4) Speed of the system is great.
If you have not done this, i recommend it. v3.6.2 per the popup
