My 2013 sonic Lt bluetooth used to connect to my iPhone 4, iPhone 4s, back up iPhone 3g, my girlfriends LG G2, and her sons iPhone 5c absolutely perfectly. If we were all in the car, it would connect to whoever is the primary phone. Over a span of a few months, the radio would have problems connecting at all and would erase all previous connected phones. Now my Bluetooth does not connect to anything. It will not even see my phone in discovery mode. The entire Bluetooth option of my radio is malfunctioning. Which is pretty ****ty when the car does not come with a cd player. And I hate aux jacks. The aux jack makes a ringing noise through the speakers. And then sometimes the aux movie crap that is impossible to figure out will make the screen black static as if to play a movie but keeps switching back and forth to aux music and aux movie. I'm pretty much stuck with listening to the sound of my intake turbo noise. The radio still sucks. I'll call the dealer pretty soon and see what's going on. Its gotta be something to do with the Bluetooth antenna or something. Maybe its been fried by the hot Las Vegas sun. Who knows. It sure does make me angry tho.
