I just bought a 2014 Mitsu Outlander Sport. The previous owners have multiple phones connected to the radio. It will not allow me to do add a phone or anything else for that matter. I have searched online for a way to reset the radiio. I even disconnected the battery , and later took the radio out and disconnected it . Everything is still there. Can someone help me with this. This is what I would call the basic car audio, no big screen, but it does of course have bluetooth. I would appreciate any help on this.
