Hi everyone I need HELP!! Hi everyone I need some help.. I have a 2012 Passant with the ( RSN315 ) Bluetooth and navigation everything was working good I was able to make calls it would load the contacts and play music make calls. The issue started some one day to the next the phone connected to the Bluetooth like it normally does except I am ((Now unable to listen to the music Everytime I hit the media button I get a message saying)) ( NO MEDIUM AVAILABLE ) I tried removing the battery for few hours , disconnecting the Bluetooth box underneath the passenger seat to reset it and Still no luck. I deleted the phone from the car and reconnected it as well as from my phone. I haven't changed phones or done any updates to it. I'm not sure what happened I've been doing lots of research and still haven't had any LUCK...the navigation and everything else is working great just I'm unable to listen to my phone's Media but I can still make phone calls and see the contact.... If someone can please help me give me advice as to what else I can try I would greatly appreciate it. I have the RSN315
