Hey Guys,

 

I had an electrical short in my car (looong story, affected a couple things). Basically, the symptoms were the battery being installed backwards (not sure if it was... looong story )

 

Now my Avic F90BT wont turn on:

 

- No lights come on it

- No attempt to boot

- 7.5A "Radio" Fuse in car's fuse block is fine

- 1A Fuse inline with the Avic is fine

 

I get a whine through the speakers normally, and this is still there. Other than that, it does nothing.

 

Ideas?

 

Thanks in advance

-John
