My Bose factory unit was lit up this morning but no sound was coming from it.

I know I am probably 2 years too late but here's the solution that I found and you won't believe it.

Answer: Check the wiring to the rear speakers. If the exposed wiring of the speaker is grounding out, the radio stops playing.

I have had this problem for the last 9 months with my 2006 Altima and just found a solution last week on someone else's post. I must have smashed something against my speaker that twisted the wiring connector so that it was touching exposed wire to bare metal. I wrapped the wire in electrical tape so it wouldn't short out anymore and the radios has been working fine.

Additionally I was having a problem with my gas gauge not correctly showing how much gas was left. Since I fixed the radio issue, my gas gauge is working correctly.

Hope that this helps someone.

It's on the speaker itself. Take a look at this picture and I hope it explains what I mean.

Right where the white plastic connector attaches to the speaker, you should see two bare wires on the speaker itself.
if those bare wires touch the metal body of the speaker, it shorts out the electrical system for the radio for some reason.
I covered the exposed wires with electrical tape and that solved my problem.
