Product Description

The C550 is Cheetah’s  newest and most advanced GPS speed and red light camera detector, designed to fully maximise the potential of our Trinity 3.0 database.  The C550 is the latest in a long line of hugely popular and award winning GPS detectors in use around the world.

You are in complete control over which type of alerts to hear and how they sound. One complete alert sequence comprises an initial heads-up chime, up to four informative spoken voice descriptions for each location, an overspeed alert tone (if travelling above the stored speed limit for that alert) and a final camera pass chime. Alert chimes can be switched on or off to match your preference. Overspeed alert tones can be individually tailored in multiple ways for each different type of alert type to meet your driving style.

The C550’s impressive, bright and easy to read LED display clearly shows all the vital driving and alert information a driver needs.  The yellow digital speedo remains visible at all times, especially in bright sunlight, and the handy clock and compass features keep you nicely informed. During an alert, the current speed flashes to highlight if you are over the speed limit and the clock switches to show a numeric distance countdown to the alert site. There is also an additional distance countdown progress bar to emphasise the alert site proximity or to keep you updated during Average Speed camera systems and Mobile enforcement zones.

The Cheetah C550 speed and red light camera detector is packed with hardware features, including connections for an external GPS antenna, car stereo mute facility, headphone socket and two separate mounting options (dash and windshield). There’s also an optional hard wire kit to allow a more professional installation in your vehicle.

Cheetah undertakes  a programme of continuous alert  enhancement, always looking to improve our multi-point false alert filtering technology and our “effective distance” false alert filtering for each camera location. Additionally, our intelligent multi-directional alert ability is enhanced by an ever increasing number of new alert descriptions to maximise the benefits of our unique Trinity 3.0 database.

The Cheetah C550 is designed from the ground up to keep getting smarter with time.
