Hi there,
I was wondering if anyone knows if there is a software update for the stock radio that comes with the HHR that has a USB memory input? I am not sure if such a thing exists. I am getting, occasionally, a glitch sound at the start of some songs stored on a USB memory. The song starts playing a few milliseconds after making said sound.

 

I doubt there’s any kind of software update, it could dust or dirt in the usb port.

 

Betcha it's the in the MPEGs.
