The Cheetah c550 GPS speed camera detector provides speed camera warnings in the UK, Europe, USA, Canada, Australia and New Zealand (subscription charges apply). The alert range ranges from 100 metres to 1000 metres and the alert range can be manually set for each type of speed camera (read below for more information). There is also an overspeed warning for a user-defined pre-set speed. Both speed cameras and red light cameras will be alerted to.

Unlike other speed camera detectors the Cheetah c550 is compatible with an external GPS antenna allowing you to locate the main unit away from the windscreen by connecting to the external GPS antenna and locating the antenna in the window with a view of the sky to receive a GPS signal.

When approaching a speed camera you will receive an overspeed warning if you are driving above the speed limit for the road. A final chime will sound when you are passing the speed camera. When driving above the speed limit at a speed camera location your current speed on the display will start to flash. You will also receive a countdown to every speed camera on screen whereby the clock will change to a distance countdown in metres. There is also a proximity bar that also counts down to the speed camera location. On screen information also identifies the speed camera type.

Cheetah c550: Auto Express - Best Buy 2016

"The latest generation of our previous favourite, the suction-mounted Cheetah c550, is our winner for its simple but effective approach. Camera and speed accuracy couldn't be faulted, and there were clear visual and audio alerts for distance and type of camera ahead. A countdown appears as you approach a camera and it'll beep if you're over the speed limit. The LED display is easy to understand and it's hard to go wrong with only a few buttons. The only improvement that could be made is if it showed the limit at all times. Subscription for updates is the best value here, too."

Reviewed by Auto Express on 16/3/2016.

Spoken voice alerts tell you exactly what the look out for at each speed camera location. For example the spoken voice will say "at the traffic lights", "on the overhead gantry", etc.

No false alerts will be received when using the Cheetah c550.

You can mute and cancel alerts completely if you choose to. This may be useful when you are driving a familiar road and you do not require full audible warnings to speed cameras.

When driving in dark conditions (i.e. at night) you can set the Cheetah c550 screen to dark mode whereby the screen will not dazzle you.

Whisper mode will make the audible alerts quieter than normal.

The speed limit that triggers an alert to you is adjustable using the speed tolerance feature. For example, if you set the tolerance to 5% when driving on a 40MPH road you will not receive an overspeed warning until you are driving at 42MPH.

You can add up to 64 of your own preset locations to be warned of. This is useful when you want a countdown to particular locations. Simply set your pre-defined location(s) and the Cheetah will alert you to them.

The Speed Cheetah c550 includes windscreen and dashboard mount for simple and easy installation either on your windscreen or on the dashboard. Recommended places to install the Cheetah c550 is in the top, middle part of the windscreen just under the rear view mirror. To increase the visibility of the screen of the Cheetah c550 you may choose to locate the Speed Cheetah c550 on the dashboard instead.

There is an option to buy an external GPS antenna which enables you to locate the speed camera readout unit away from the dashboard as when using the external GPS antenna it will not need to have a view of the sky (only the GPS antenna will need to receive the GPS signal).

Cheetah c550 Questions and Answers

Question: Is the Cheetah legal in Italy and Switzerland?

Answer: We are based in the UK, and while we can confirm that the Cheetah c550 is fully legal to use on UK roads. We do not know the legality for other European countries. I would therefore recommend that you contact the Police in both Italy and Switzerland to enquire whether GPS only speed camera warning devices are legal to own and operate.

Certainly, the Cheetah c550 Trinity database includes speed camera locations for both Italy and Switzerland.

Question: Does the c550 pick up mobile radar van traps and mobile guns? Also, I recently purchased a cheap detector and goes off continuously with traffic lights etc. Does the Cheetah go off at all traffic lights?

Answer: The Cheetah c550 does NOT feature a radar or laser detector. All of the Cheetah c550 alerts are derived exclusively via the units internal and updatable GPS based speed camera database (subscription charges apply). The Cheetah c550 database features both fixed and mobile speed camera locations.

It sounds like the speed camera detector you bought features a radar detector. A radar detector detects K band frequency among others. Any device using K band will be alerted to and detected by a radar based detector. This can include; over-speed speed limit advisory signs, shop doorway sensors e.g. automatic doors on petrol station forecourts, traffic light signals, etc.

The Cheetah c550, which took the Best Buy award in Auto Express in 2016 will NOT provide any false alerts. If the fixed or mobile speed camera location is in the database, the unit will alert and warn you. If the location is not in the database, you won't receive any warning, thus eliminating annoying false alerts.
