After a quick stop at the grocery store I returned to my X. After getting in and starting the vehicle I pushed the radio power knob several times. The orange light stayed on and wouldn’t turn off. I waited for about thirty seconds and the light finally went out. I tried to turn the radio on, but it wouldn’t budge. I thought about it for a minute, and then decided to turn the car off and on to try to reset the radio module. This didn’t work and now I am writing this in search of answers. I lost all audio functions including radio, voice recognition, navigation, and phone. I tried calling out with the Bluetooth phone system, it starts to dial (I assume since there is no audio to confirm this) then hangs up. The navigation system appears to be working, but there are no audio prompts. Voice recognition is also working because the commands are displayed on the instrument culture, but there is no audio. Any advice would be appreciated.
