Angry Why won't MB Bluetooth auto reconnect to some bluetooth devices when I start my car.
My MB Bluetooth won't auto reconnect to some bluetooth devices when I start my car. Not sure why.

I have to manually select the device to reconnect every time I start the car.

I even get a message after initial pairing that tells me a device won't auto reconnect. Weird.



Does any tech savvy person know what the connected device is missing to cause this?

I've been trying to figure out this for years.

For example, My Shanling M6U DAP doesn't have this issue or my Galaxy S24 Ultra.

MB Bluetooth will reconnect and continue playing music, everytime I start my car.
