Formed in 1973, GLM Security & Sound began by providing many of the mobile electronics products that people wanted: car stereos, car alarms, and other automotive products. But as times, technology, and the world changed, so did GLM.

So whether you want to prevent someone from stealing your car, get your car back if it is stolen, or you want your kids to be able to play games or watch videos in the back of the family vehicle, GLM is going to satisfy your need to not just keep up with the times, but stay ahead of them.
