The command center was not compatible with BT in my car--it kept turning the BT off. One replacement Droid Maxx later, and three trips to the car dealership, I still had the same problem. As soon as the command center was disabled, BT worked perfectly. I use OneMoreClock widget which gives me battery life, date, time and weather. It doesn't give me the weather in multiple locations, like the Droid Command Center does, but I can live with that.
