2011 Nissan Murano "Reading file..."

[bbfelts]

The Murano finally recognizes my Pi Zero as an iPod so it tries to connect, but it stays at "Reading file..." and never goes any farther. I suspect it's doing some kind of iPod verification - all the other devices I've tried that emulate an iPod interface have failed (WMA2000 is an example).

I should note that all Apple iPod/iPhones I've tried work fine with this interface.

Below is the debug output from the ipod program:

Our other car (2011 Nissan Rogue w/Navigation) hangs in the same spot, but the head unit doesn't even switch to the iPod screen.

Same results...unless I did something wrong:
