I know this sounds lame but my '4' button is loose and comes right off the HU. Anybody else have a problem like this? I don't know if its the button or where it fits into the HU causing the problem but it drives me crazy. All functions work fine, and I'm not in a position to upgrade my sound system but I want to fix this.

Does anyone know if the other buttons pop off? I'm thinking about popping one off and seeing if it has the same problem but I don't want to break another one. I'm very **** about stuff like this so it really gets on my nerves.

Thanks
