Sooooo I had the Now Loading All Apps problem on my 2015 Q50 and like an idiot hit the reset button in the diagnostic menu. Now I only have 3 buttons, no map, a broken clock, and no stereo. I took it to the Infiniti and they said that they can not perform a reset or anything to make it functional again. The cost of replacement is $4300. Not something I'd like to do. If I were to get a Pheonix vertical screen or the like, would I regain functionality of my speakers? If not what other course of action do I have? Get an A/V unit from the junkyard?
