Help me come up with a name for a business by dejaiman

I have a small business that provides GPS Tracking for anti-theft, stolen vehicles and fleet management. I need a name for the business, the name CANNOT have the word GPS. Locally the general public does not understand "GPS" and furthermore, if they think they know GPS, they think it is for navigation. I want the name make the public know that this business is about car security and car protection. The name cannot be too long, must be memorable, must flow, must not be hard to say, (example: on the phone: "Hello, good morning, xxxxxxxx etc etc..") and must convey the message of car security. (Prize: 30)
