Hello, I’ve just became a owner of a Iphone 15 pro max, yesterday I tried to connect it to my car audio(I’m not sure what its called in english so I add a picture of it) wihch is an older module, it has bluetooth 3.0., when I try to connect it’s says “your iphone can’t connect anymore to the following”mvh-29bt”, delete connection then try again” It was working with my 2020 SE maybe it’s too old for my new phone? Anyone has expeirence with anything like this?” Sorry if I made any grammar mistake it’s not my first language.
I had a similar issue with my Pixel phone. It turns out the minimum Bluetooth AVRCP version has been updated and I could no longer pair or connect to my older car stereo. Android has a setting in the developer options to change the AVRCP version and after I changed this to an older version the pairing worked again.
Unfortunately it doesn’t look like iOS has this setting so you probably need a new stereo. You can also buy a new Bluetooth audio adapter for your stereo that supports the newer Bluetooth standard.
