The thief smashes one of the vehicle's windows and takes anything of value that is visible, i.e., eyeglasses, sunglasses, loose change, books, clothing, cellular telephones, etc. After parking your vehicle, take your valuables with you. If you are unable to do so, be sure to place them out of sight. Store them in the vehicle's trunk. If your vehicle does not have a trunk, put the item or items under the seat or place a covering over them.
Cellular phones are a prime target.
Those mounted on the dashboard or console are particularly vulnerable. Slide the cellular phone out of its mounting cradle and secure same. If you are unable to remove the phone in this manner, contact your cellular phone vendor and have a cradle installed that will enable you to remove the phone so that is can be secured.
