Once I establish a connection, it is stable throughout my journey, but quite often when I get in the car, it won't connect even though the phone shows that it is charging, and I have to unplug the cable and try again. Sometimes I plug the phone in before I start the car and sometimes afterwards; this doesn't seem to make any difference.
I believe that I have a fairly good cable so I don't think that is the problem. Has anyone else experienced this?
I have a Galaxy S8+ with all of the latest updates.
PS What is the problem with a Bluetooth connection instead? Surely it has the necessary bandwidth?
