Lol, I guess I'm not explaining myself properly.
You can set an android phone to ask every connection, but this screws up my car stereo when it plugs it in. I just wanted to know if there's a quick way to change the default connection type from 'Disk drive' to 'Charge' and vice-versa. I know how to set it to do it automatically and manually, but I want a quick way of doing this via a widget or a shortcut, and can't find a way to do this...
