I have a 2013 XLE running software version 3.2 and using a Samsung Galaxy Note 4. When I connect to Bluetooth, it will work for anywhere between 1-30 minutes, and then it drops. The phone thinks it's still connected and will keep playing music though it's silent. The display on the radio shows "no bluetooth device connected" and if I try to go to setup, it shows bluetooth off, the box is unchecked and nothing will let me do anything in the setup menu until I shut the engine off and back on. Then the cycle starts over again. It's driving me nuts, I have tried everything to fix it and nothing works. My previous phone was an LG and I didn't have the issue. I brought it up at my last service and Toyota was of no help. This is a popular car and a popular phone, it can't be a unique issue. Thanks in advance for any assistance.
