My car vibrates a lot, so I bought the car dock to ensure a perfect fit. But I noticed that there's a vibrating noise coming from the phone when the car is turned on. This doesn't happen when the phone is not in the dock, and I figured out it was either the volume rocker or the lock button making the noise. I found out by violently shaking the droid.
Anyways, it turns out to be the volume rocker (maybe the lock button too). Anybody experience this? Any ideas on how to stabilize these buttons so that they aren't loose enough to make noise?
