Title. Pisses me off mildly. I’ve got my earbud in for a reason (quick drive) and Bluetooth decides to connect to the car when it starts. The cars’ head unit takes forever to start and have to manually switch over to Bluetooth mode (while the audio is already playing) and the volume is way down.
And when you get out of the car it doesn’t automatically connect back to the earbuds.
It’s more than mildly when I’m shoveling snow and my wife starts the car to warm up. Every time I get within 10 feet of the car my phone disconnects my earbuds. Same if I’m doing yardwork when she gets home.
Even more annoying because my phone can output to two Bluetooth devices at once. If you think it’s so important the new device needs connecting just do both.
But they should never automatically change Bluetooth devices. If I’m getting in the car you can switch devices when I pull out my earbuds and they shut off when I put them in their case.
