Was listening to Sirius and had USB plugged into Iphone. Made a phone call using the steering wheels controls and ended the call. From that point on there is no sound. I can tune to all stations (Sirius, FM, AM etc) but hear nothing.

Where can I start? Fuse? Where is the fuse location?

Searched but haven't seen this on 7th gen

 

Well...had the car off since I posted this and turned it back on and the sound was back.

Didn't see this was a common issue anywhere so I'll look at fuses first if this happens again.

 

Its not the fuses, if the fuse blows, it cant miraculously heal itself.
Sorry, cant help you identify the problem. Speakers are not powered typically, so if your radio works, and you have no sound, then the problem is in the radio or amp.

 

When you use your phone, steering wheel controls, USB, does Bluetooth disconnect the speakers, or ear buds disconnecting the speakers. IT certainly is not a fuse as the speakers are not powered and you still have power to the devices.
