Just purchased a 2010 250C paired my Android but it does not automatically connects all the time any thoughts and of I get a call drop while driving the Bluetooth goes out not sure why not?

 

Basic troubleshooting stuff...Do you have a FitBit or other device paired to the Android?
Do you completely shut down the phone regularly?
Once a week is enough...not yet this year is bad.
Up to date OS? KitKat was troublesome.
Are you attempting to charge the phone using the USB port? Use a 12v adapter for charging.
Use the USB port for non phone devices, iPod is best, flashdrive and iPads OK

 

I deleted it and paired it again and I seems t be working steady
