Can you see the screenshot now? Rolling marbles seems a fitting description...it's quite possibly always done that because I generally don't operate a vehicle without loud music unless I'm listening for diagnostics. Definitely not loud, grindy, or screechy. I'll try reseating it but I won't get to it until Thursday night. I'm an RN and we work 12 hour shifts +shift change report +charting that we didn't get done during that 12 hours, so I don't do much of anything else on nights I work.
