Yeah, the bluetooth in my car is so hopelessly pathological that I always turn off the bluetooth in my phone and turn the internal phone speakers up if I want to use the maps app. If I don't, first it will immediately pick some song at random on my phone and play it at full volume without my asking. If the radio is turned off, it will still connect to the phone, which disables the phone speakers, but then it will not make any sound at all. Or it will connect up but will turn the volume all the way down which also results in no sound. Sometimes it will randomly connect to various devices in the car. Sometimes if you plug in the phone to recharge but leave the bluetooth on it will turn off the phone speakers but also not make any sound from the car speakers. It's bad. The whole system is actively hostile to the user.

Car bluetooth is a whole different world of terrible software. I wish there was a standardized interface that car manufacturers would use, rather than hand-rolling their own.
