Reset factory settings/ Radio issue

I recently picked up a 2005 E55 and while going threw the menu's I did a restore factory settings. Everything was fine but I noticed my radio is no longer putting out sound, it's lights up like it should I can swap between Bluetooth and am/fm still no sound.
My question is since its an after market Pioneer deck is there something that's causing a conflict from deck sending sound to the car.
I did a search on the forums and saw maybe that it's a fuse issue. But I'm not sure since this just happened after I reset settings.
On a side note, I can say I have never been more in love with a car than I am with beast of a machine lol.
Thanks for any help and look forward to talking to you guys soon!
