Before anyone says search the history trust me I have. From what I can tell it was a common issue that occurred where the speakers would just not work. The difference I have from what I have read is that all my knobs and controls work. If I turn volume up it shows on my screen. I have spoken with the guy to upgrade to the 14 model to gain cameras and Bluetooth radio. I just don't want to spend 2k plus and still not have it fixed. I also read to check the amp under the driver seat but I don't see one there. My model has the Bose sound system if that matters. Please if anyone can point me in the right direction I'd be very grateful.
