How to delete Phone Calls on a Plug -In
 

My 2012 Advanced Plug in will list all of my phone calls, however there is not an option to delete all of my call history. Been back to the dealership and 2 sales people and 1 service manager tried and could not figure anything out.
It was suggested to bring the car in for a scheduled service appointment for them to diagnosis.

Does anyone have have a suggestion how to do this without disengaging the phone from Bluetooth which means I have to reconnect the phone. This was the only way to clear the phone log.
