The police will "do their job" if you stay out of the way and allow them to. Forget about the silly CSI cans from his trash idea, a personal visit, and anything else that will tip the suspect that he's been identified and is under investigation (if it's not too late for that already). If you committed this crime and knew the police were investigating you personally would you keep keep the stolen property - likley to be the only physical evidence linking you to the crime - or would you dump it immediately?

These cases take time - don't forget, yours is one of dozens they're responsible for at the moment and the victim in every one of those cases thinks theirs is the most important.

You'll be more help making sure you have serial numbers and the rest of the information they'll need if they are able to find and recover your property.

The Garmin can't be tracked - good idea though.

Make sure you reprogram the garage door opener if you haven't already done so.
