@Cee Jay ,. thanks. I'll try the canned air and see what that does. I'm not sure I'm techie enough to remove the dash pieces... Is the technical manual you refer to posted in the forum somewhere? I only have the owners manual; not the technical one.

Cheers,

 

Thanks @jahummer !

 

How did you determine it was the navigation draining your battery?

 

As I wrote in the initial post, there is a constant hum from the navi can, as if the board was still rotating and it would not slide out.

 

I have never heard mine , I don't believe I have ever used my navi though. I do sometimes have a parasitic battery drain, no idea from where.
