Aren't these things just for people who run red lights or speed? Why do I need one?

Camera detectors are not niche products designed for speeders or red light runners. Sure, they will help you avoid a ticket but they are also every-day road safety systems for all responsible drivers that help to improve situational awareness.

Nobody can fully concentrate for 100% of the time. All of us have occasional lapses which could easily result in an accident or a fine and licence endorsements. Collisions, fines or penalty points can all result in increased car insurance premiums to say nothing of the implications for personal safety.

80% of auto accidents involve driver distraction. (Virginia Tech Study, 2006) When speed cameras are placed in accident blackpots, using a camera detector makes sure that you are not distracted at a vital time, i.e. when you're driving along that stretch of road that has a bad history of accidents. Camera detectors remind you to be paying attention when you need it most.

Almost 60% of red-light running in the USA is caused by drivers not paying attention or becoming confused. (Federal Highway Administration Statistics). A camera detector makes sure you won't accidentally run a light yourself by drawing your attention in advance to the dangerous junction approaching. It gives you time to think, concentrate and plan ahead safely.

33% of red-light running is intentional. (Federal Highway Administration Statistics). Red light cameras are placed where they are most likely to catch red light runners so being reminded to pay extra attention at these junctions will not only help you avoid a fine yourself... it may even help you avoid a reckless driver!

It’s been well documented that rear end collisions can increase at red light camera locations, caused by drivers panic breaking at yellow lights to avoid a ticket. Being more aware of these camera intersections in advance makes you better prepared to avoid that type of accident.

To make red light cameras financially viable most cities have to enforce right turn on red, so even if you proceed through a light at 2 mph, a perfectly safe driving practice that you may have been doing for more than 30 years, it can suddenly lead to an unjust ticket and you being branded a red light runner. Tickets are expensive and in some states like California and Arizona can lead to points on your license that increase you car insurance for years to come.

Finally, the more accurate GPS speedometer, combined with advisory speed limit announcements during camera alerts and the optional Speed Reminder features, means that a GPS camera detector will help you to become much more aware of your speed at all times, which can only have positive safety implications for all.

Is the GPSmirror legal?

Most governments recognize the fact that GPS Detectors give drivers advance awareness of the accident areas where cameras are located and act as an electronic extension of the existing road signage. They are genuine road safety aids which can help reduce casualty figures. Police view these devices as useful road safety tools because they help all drivers, particularly when they are in unfamiliar areas, to have the same level of knowledge about accident areas and camera locations as a reasonably informed local driver.

 

USA and Canada

Yes – GPS camera location is legal in every state in the USA and Canada.

 

United Kingdom 

Yes – GPS camera location is legal in the United Kingdom.

The UK Government have stated that using GPS to warn of speed camera locations is legal.
"The Government will not be prohibiting those devices that rely on Global Positioning System (GPS) technology to warn drivers of published camera sites or posted speed limits, as these compliment the Government's policy to ensure that camera sites are visible and conspicuous to drivers, and so help deter excessive and inappropriate speeds on the roads."


Radar and laser based detectors and jammers operate differently to GPS based camera warning systems. There is draft legislation in place in the UK that would ban the use of detectors and jammers, but this legislation is not yet enacted.

 

Germany

There is currently no legislation banning the use of GPS to warn of speed camera locations in Germany, but there has not been any legal precedent to explicitly confirm this position.

Radar and laser based detectors and jammers operate differently to GPS based camera warning systems. There is legislation in place in Germany that bans the use of detectors and jammers.

 

France

All types of camera warning systems are banned in France.

 

Switzerland 

All types of camera warning systems are banned in Switzerland.

 

Liechtenstein 

All types of camera warning systems are banned in Liechtenstein.

 

Other countries

If a country is not listed above we do not currently have any information about specific legislation governing the use of speed camera warning systems for that country.


Please note: The driver of a vehicle will most likely be held accountable under local laws for the use of any camera warning systems in or on a vehicle.

How do I fit the GPSmirror?

The GPSmirror is easy to fit yourself. It clips over your existing factory mirror and the power cord is long enough to tuck discreetly away behind the roof liner, A pillar trim, under the glove box and round to your vehicle power socket. There is ON/OFF slider switch on the power cord.

We have a fitting video here:
www.youtube.com/watch?v=phn-TgeotZk

Will it fit over my factory mirror?

The GPSmirror is designed to fit most stock mirrors in use today, even the oversize mirrors in some modern vehicles. You can see the dimensions of the GPSmirror here:

Will it prevent me using my sun visors?

On most vehicles there is not normally an issue. On some vehicles you may have to offset the mirror slightly to the passenger side and therefore it may partially restrict the use of the passenger side visor. If this is an issue for you, Cheetah offers a 30 day no questions money back guarantee on all units purchased directly from Cheetah.

Is the view from the GPSmirror the same as my factory mirror?

No. The GPSmirror uses a special wide-angle mirror glass which greatly increases your rear vision and helps to eliminate blind spots on many cars. It also lets you keep an eye on any children in the back seat at the same time at the same time as monitoring traffic. It’s much better for use on freeways because it lets you track overtaking vehicles for longer. Some customers take a couple of days to get used to the different view, but the once they are used to it, do not want to be without it. Most users report feeling “blind” without it if they ever have to return to using a normal mirror again. If you are one of the few customers for whom the enhanced view is not suitable, remember Cheetah offers a 30 day money back guarantee on all units purchased direct from Cheetah.

I have an automatic dimming mirror. can I still use the GPSmirror?

Yes. In fact you will probably find it gives better night vision than your auto-dimming mirror. The problem with a lot of auto-dimming mirrors at night is that when someone with bright lights is behind you, the mirror goes so dark it becomes almost useless as a mirror and you can’t make out anything that’s happening behind you. In side by side comparisons with factory fitted automatic dimming mirrors, 93% of customers prefer the specialized NIGHTblue anti-glare coating of the GPSmirror, reporting better night vision while not being dazzled.

I have an OnStar mirror and I use the OnStar service. Can I still use the GPSmirror?

The GPSmirror will actually fit fine over an OnStar mirror, but doing so would obviously cover up the OnStar buttons and would prevent their easy use. We recommend OnStar customers purchase the C100 model instead.

Back to top

 

 

 

 

 

I don't have a mirror in my truck. Can I still use the GPSmirror?

We’re recommend you buy the C100 instead. It has all the same features and performance but it’s in a more traditional design that’s small and portable.

Back to top

 

 

 

 

 

What's the difference between the C100 and the GPSmirror?
Both detectors are built on the same platform so they have identical features and performance. The only difference is the form factor. The C100 is small and portable. It’s about two thirds the size of a radar detector making it ideal for business travelers, OnStar users, truckers or delivery drivers (nowhere to mount the mirror) or anyone who prefers the more traditional style of car electronics. The GPSmirror is a wide angle safety mirror, with a built-in C100 camera detector, that clips over your existing rear view mirror to give a very discreet install that’s hassle free; you don’t have to hide it every time you exit the vehicle. As both units work the same, including the False Alarm Suppression Technology for radar detectors, the choice really comes down to a matter of personal taste over how you mount the detector.

I am not getting satellite lock / satellite lock keeps dropping / speed jumps up and down. Is there a problem with my windshield?

If the GPS signal is partially blocked by heavy trees, steep walls or a tunnel, the speed display might look slightly erratic for a short time until you clear the obstruction.

If you have clear line of sight to the sky above and still experience this problem, it’s likely that you have an “Athermic” windshield. “Athermic” glass (sometimes called comfort glass, solar reflective or UV reflective) can prevent satellite signals getting through it to reach the internal GPS antenna which results in either no speed being displayed, intermittent or erratic speeds, or even an extreme amount of time to achieve a satellite lock. This glass also greatly reduces the performance of radar detectors because it cuts down the amount of radar signals entering the vehicle.

There are a three easy ways to check your windshield to see if it is the cause of the problem.

1. If you have polarized sunglasses, look at the windshield through them to see if it looks purple.

2. In a stationary vehicle, hold your Cheetah GPS detector out of the window to see if satellite lock is faster.

3. Click here for the Athermic Windshields – Vehicle List. This list is not exhaustive but is correct to the best our knowledge at the time of writing.

If your windshield is Athermic, you can purchase a remote extension antenna from Cheetah to collect GPS signals through the rear window or from the outside of the vehicle.

How do I update the GPSmirror?
We recommend you update your database every month. Updates require a PC with Windows 98 or above with internet access.

Once you have loaded the download software on your PC, you connect the detector using the USB cable provided and run the software program. You have to make sure your PC is connected to the internet before performing an update but you don't have to visit any links or web pages, as this is all done automatically by the PC software.

We have a video on Updates which you can view here:
www.youtube.com/watch?v=Y89h41z8c3s

For full, in-depth update instructions, click here.

Please note that we do not provide specific update software for MAC computers, however if your MAC is running the Windows emulation software, you will be able to use our standard software.

I've found a new camera location that is not in the database yet. How do I report it?

You should report any new camera sightings here. Alternatively you can send an email to with as much information as you can. Our database team will check out your report and add it to the Trinity™ database.

You can always store a new camera as a personal location, which can be deleted once the camera has been added to the central Trinity database.

Back to top
How do I store/delete Personal Locations?

We have a video on Locations which you can view here: www.youtube.com/watch?v=V6l-1ub-fvk

To store up to 100 personal locations
Press button 1 [main menu] three times to arm the GPSmirror for personal locations. The number of the next available memory position is now shown on the right hand side of the display screen. When you are at the exact location you want to store, press button 4 [save] and it will then be stored in that memory position.

Personal alerts are directional so will only alert when you are traveling back to the location from the same direction.

The warning distance for personal alerts is around 200 yards, so store the personal location in at a suitable point to give plenty of warning.

To delete an individual personal location
Sometime you may want to delete a particular personal alert; for example, if you store one in your driveway. During a personal alert, the first number shown on the screen is the memory position of that particular alert. Remember this number so you can navigate to that individual entry in the menu system. Press button 1 [main menu] three times to enter the personal locations section of the menu structure. Then use button 2 [plus] or button 3 [minus] to navigate up or down to the memory position you wish to delete. When you find the correct one, press and hold button 4 until you hear the voice announcement "Location deleted."

To delete all your stored personal locations
Hold down buttons 2 & 3 and then switch on the power supply.

How do I change the time on the clock?

The clock setting is taking from the GPS satellite signal. As this is a global system it does not automatically adjust between time zones. You can easily adjust the clock setting to your local time zone by following the instructions in your manual.

Press button 1 repeatedly to access the Time Zone feature in the main menu. Then use button 2 to adjust the setting up, or button 3 to move it down. When you have the correct GMT offset, press button 4 to save.

Back to top
Is there a demonstration mode to show me camera alerts?

Yes. Press and hold button 1 [main menu] until the demonstration mode starts. It will cycle through the various camera alerts that can be given by the detector. e.g. GATSO ahead, limit 30

To exit demonstration mode, just remove the power.

Why is the speed display on my GPSmirror different to my car's speedometer?

All car manufacturers, by law, have to calibrate their speedometers to make sure that the vehicle is never actually traveling faster than is indicated on the display. This means that, in practice, car speedos will always slightly overestimate your true speed for safety reasons. This variance can change from model to model and maker to maker. Your car’s speedo can also become slightly inaccurate if you change the size of your wheels or tires.

At a constant speed the GPS speedo in your GPSmirror is more accurate than the one in your car because GPS speed readings are calculated from an independent source.

During acceleration and deceleration, your car speedo will be more accurate that the GPS speedo. GPS receivers only check their position once a second so will always have a slight lag before the reading is updated to show your new speed. When you reach a steady speed, the GPS speedo returns to being the more accurate measure.

Back to top
Can I move my GPSmirror between vehicles?

Yes, the GPSmirror has been designed to be easily transferable between vehicles. Just clip it off one mirror and clip it onto the other one. However we do recommend you purchase an extra power cable to install in the second vehicle as this will make it much faster to swap over. You can purchase extra power cords separately.

Back to top
Can I hardwire the GPSmirror?

Yes. You can purchase a hard-wire power supply. Alternatively, the power cable can be used for hardwiring if you remove the cigar lighter plug. The GPSmirror must be protected by a 2 Amp in-line fuse and must be connected to a switched supply in the car, i.e. when the engine is not running there should be no supply to your GPSmirror. If you are unsure how to do this then consult a professional automotive electrician.

Back to top
How do I adjust or switch off the overspeed alert?

The Overspeed Alert is a standard feature on many GPS detectors and is very useful if you want to be reminded to slow down if you accidentally drift over the speed limit, for example on a freeway / motorway.

You can easily change the Overspeed Alert value by pressing the following button sequence:

Press button 1 twice to access the Overspeed Alert feature in the main menu. Then use button 2 to adjust the setting up, or button 3 to move it down. When you have the correct speed setting you want to use, press button 4 to save.

If you want to disable Overspeed Alerts completely, set it for the value 255.

Is the GPSmirror like a radar detector?

No. The GPSmirror uses completely different technology to a radar detector. The GPSmirror uses GPS location to check its position against an onboard database of fixed safety camera locations, accident blackspots and common mobile sites. When you are approaching any of these stored locations, the GPSmirror provides a warning.

Radar detectors do not alert to most speed and red light cameras because the cameras use sensors buried in the ground, so there are no radar signals to be detected in the first place. Radar detectors also give hundreds of false alarms for other radar sources like automatic door sensors. The GPSmirror does not false alarm for these sources – it only alerts to locations that are stored in its memory.

How do I link up a radar detector or laser jammer to the GPSmirror?

You can use the GPSmirror to suppress false alarms on a radar detector, or wirelessly integrate with a laser jammer, by purchasing the appropriate Cheetah Interface. All Cheetah Interfaces are plug & go so they are easy to fit yourself and require no technical skills.

For more information, please read FAQs on Radar Detector Interfaces and FAQs on Laser Jammer Interfaces

Can I interface a radar detector and a laser jammer at the same time?

Yes, there is no limit to the amount of laser jammer interfaces or radar detector interfaces you can have working at the same time with your Cheetah C100 or GPSmirror.
