I have a 2015 3s Touring with OEM navi and such. I don't make calls much when driving but when I do or when someone calls me while I have my phone connected to the car's Bluetooth the call will always end because the Bluetooth looses connection and ends the call. Then by itself it will reconnect and redial. This has happened every single time I'm trying to made or receive calls from my car via the car's Bluetooth. Has this happened to anyone here? Is there a fix? Yesterday I updated the Navigation Map software via Mazda's Toolbox. When I do that does it only update the map or does it also update any other software or firmware that may possibly fix this problem? Thanks.
