When I bought my accord it had a sony cd player in it. It has this ring around it that holds it in the factory location with the little cubby hole underneath.

The ring has these little clips that hold it in place and it will stay in place for a few hours but once I hit a bump it falls down and I have to pull it completely out and reposition it again.

Is there a different kit that holds in better I can pick up or some way to rig it in there so it isn't constantly falling out on me?

Here's a pic that may show what I mean:
