Okay guys, here's my take.
This has EVERYTHING to do with MFT/MLT. Period.
I own a 2012 Fiesta with Sync. Nothing fancy, no touch screen, nav, or anything like that.
I also own a Razr Maxx HD running 4.1.2
I have no problems running pandora, iHeart radio, slacker, MYXM, Sync Destinations. No skips, dropouts at all thru Bluetooth.
This is a Ford problem. Period. MFT/MLT is very well known for its craptacular service. Go after FORD.
That is all.....
P.S. OTOH , I DO have to have Google Play running on the phone prior to using the Bluetooth Audio Stream(personal music). My previous phone(BB9700) I could just play my music from the get go. I.E. cold start. Working on THAT problem......
