My 2010 F150 has Bluetooth and I connect regularly to my cell phone and use it to call out and receive calls. As of two days so ago it will connect but it stopped asking to "please say a command" etc. Now it's completely silent....what happened? Is there a way to reset the media center?

 

You may be due for an update.

If you don't have a Sync account, you'll have to register, then that may help you get you Sync working again.
I went to an aftermarket stereo that doesn't have near the issues.

After my last phone update (AT&T) I uninstalled and reinstalled (paired) the phone with Sync and its working fine again, It's a simple process.
