So I just came back from Atlantic City last night. I had no problems with my radio at all but this morning when I started my car my radio was off. I can't switch to any source (CD, iPod, Radio). All the lights on the buttons, below the Navigation screen, are all turned off. No radio source is turning on. My Navigation is working just fine though. On Monday I installed the Navi kit but everything was working just fine during the week. Anything to look for before I pull out the entire unit?

 

Any chance this would be covered by warranty? You mentioned that you installed the Navi kit, not the dealership...

 

if I need to go to the stealership then I will remove the kits

 

Sounds like you most likely had a connection come loose.
Recheck your connections

 

Maybe its a fuse issue??

 

i also think that you blew the fuse.

 

I would recheck your connections. I had a similar problem when I installed the VAIS on my car. I replugged everything back in and problem went away.
