CD Error with Shaker 500

[dagamaard]

Hi All -

When I try to eject a CD from my Shaker 500, it just makes a whirring noise for a few seconds, then displays "CD Error".

How do I fix this? Is there a way to take out the head unit and pry the CDs loose? Or do I have to just replace the head unit?

For context, this started happening after the battery went dead.

Thanks!
