I would like to update the firmware on my appradio.  It is currently the 8.05 and I want to load the 8.05 US version so I can use pandora.

 

Problem is, I can't even get the 'update firmware' button to activate?  It just stays grey all the time.

 

I have the parking brake bypass so don't think that is the problem.  I have tried with bluetooth and all devices connected as well as disconnected, not change.

 

Any ideas?
