Why do I need a Radar Detector Interface?

The main reason for buying a Radar Detector Interface for the C100 or GPSmirror is to integrate radar detector alerts onto the Cheetah GPS detector so you get all your alerts from the one system inside your car. Cheetah GPS detectors have several features which allow you to suppress most of the annoying false alarms on your existing detector. Very cool!

Alert Speed lets you automatically mute all radar alerts below your chosen speed setting. Radar alerts are only played when you drive faster than the speed threshold. This is a simple and highly effective way of getting rid of all those alerts in mall car parks, at traffic lights from local convenience stores and gas stations or when you’re traveling at low speeds in town and don’t really need to hear detector alerts anyway.

Will it work with my radar detector?

Radar Detector Interfaces are compatible with the Valentine One, Beltronics STi Driver, Escort 8500 X50, and Beltronics RX65 as well as several remote mounted systems like the Escort SR7, SR7 plus or SRX and the Target EVO 966RM. Some other remote radar detector systems like the Beltronics 975 or Vector LR and the Target EVO 966R can be modified to be made compatible with our RDI. There is a small factory charge for this conversion service. Please contact us for more details if you are interested.

How does it connect to my radar detector?
Please visit the Online Manuals page to download the instructions for your make and model of detector. It contains a schematic diagram of connections.

Can I use the RDI with a laser jammer interface at the same time?

Yes, there is no limit to the amount of laser jammer interfaces or radar detector interfaces you can have working with your Cheetah GPS detector. We know one customer who runs three laser jammers and 4 detectors with a single Cheetah GPS detector.

Do I need to have a Cheetah C100 or a GPSmirror?

Yes. You need to have some form of Cheetah display for the RDI to wireless link with. This means you need to have the C100 camera detector, the GPSmirror, the Cheetah VizAlert motorcycle helmet display or the Cheetah M27 Rider. You need to have something to display the detector alerts.

Will the RDI work with the Cheetah C50?

No. The C50 is our new entry level GPS camera detector and it is a stand-alone detector. It does not have the extra circuitry and firmware to wirelessly link our interfaces to display radar and laser alerts. There is no problem in running the two products in the same car at the same time, but they will not wirelessly link together.

I have a Cheetah M27 Rider laser jammer on my motorcycle. Will the RDI work with that?

Yes, but please note we offer a slightly different RDI package for motorcycles. You already have the POWERnode as part of the M27 Rider system so the M27 RDI kit comes with a Y splitter cable instead to hook into that, which brings the price down a little. You can purchase the motorcycle version from the M27 RDI product page.

When I switch the radar detector off, the Wireless link LED does not go off instantly. Why is that?

The reason there is a small delay in the LED light being switched off is down to the way that all wireless technology works.

When the RDI is first switched on, the wireless transmitter connected to the detector sends out a “Communication Check” signal (CC signal). When the Cheetah detector receives this CC signal, it illuminates its wireless link LED – that’s the little satellite dish symbol on the display unit – to show that the system is operating normally, and the wireless connection has been established.

This CC signal is a self test function which is repeated approximately every 20 seconds. Receiving the CC signal tells the Cheetah detector to keep the wireless link LED illuminated. If the Cheetah detector unit does not receive a CC Signal for 2 cycles then the display unit will switch OFF the wireless link LED to warn you that the wireless connection has been lost.

If you switch your Cheetah detector on first, before your RDI/radar detector, the Cheetah detector is ready to receive the first CC signal as soon as the RDI/radar detector turns on. This way the wireless link LED will appear very quickly. The reason why there is a short delay in the LED turning off when you switch off the RDI/radar detector is because the Cheetah detector is waiting for two missed CC signals before turning off the wireless link LED. It can vary from 21-40 seconds for two CC signal cycles to happen – it depends on where in the cycles you killed the power.

If you switch the Cheetah detector on after your RDI/radar detector, the Cheetah detector will have missed the first CC signal so the wireless link LED will not illuminate until it receives the next CC signal. This can take a maximum of 20 seconds – it depends on when in the CC signal cycle the Cheetah detector is switched on. PLEASE NOTE: THE RDI BECOMES FULLY FUNCTIONAL 2 SECONDS AFTER INITIAL POWER ON AND RADAR ALERTS WILL STILL BE RELAYED INSTANTLY BY THE CHEETAH DETECTOR EVEN IF THE WIRELESS LINK LIGHT ON THE DISPLAY UNIT IS NOT YET ILLUMINATED UNTIL THE NEXT CC SIGNAL.

I noticed a small flicker on the LEDs in the display unit every 20 seconds or so. What is that?

You may notice a slight flash of the Wireless Link LED whenever the Cheetah detector receives a CC signal (Communication Check Signal). This is normal. It is a visible sign of the self test function and it does NOT mean that there is a problem with the Wireless Link.

The CC signal does not interfere with alarm signals being transmitted by the Radar Detector Interface in any way. So even if you were hit with radar or laser at exactly the same time as the CC signal, you will get the normal alert.

Does it change my detector’s performance?

No, your radar detector has the exact same performance. Essentially all the RDI is doing is replacing the speaker in your own radar detector with a new wireless alert system that alerts through the Cheetah GPS detector. It doesn’t enhance or impact the detection performance in any way.

I seem to be getting different alerts on my Escort/Beltronics radar detector and my Cheetah GPS detector.What do I do?

Check the instruction manual. You must set up your radar detector’s menu system in the exact way we describe. The most common mistake is that your detector’s alert tones are set for LOUD and not STANDARD.

You have to set your radar detector according to the exact instructions in the manual. If you have lost your manual you can download one from the Online Manuals page.

No wireless Link symbol

Check the power connections to the RDI and radar detector.

On the Valentine One models, please note that the Cheetah cable between the RDI and the Valentine One must be inserted the correct way round, otherwise it will not work. The ends of the cable are labeled and the connector with the metal sleeve must be installed into the RDI transmitter (labeled as the RADARnode.)

I’m getting a constant KU Band alert

This is a warning tone to let you know that the RDI software card is not correctly inserted into the side of the RADARnode transmitter. Switch off power, remove the card and re-insert flush.

What are the cable and the button on the side of the RDI RADARnode transmitter for?

The button is a signal test button for the VizAlert motorcycle helmet display. It makes the VizAlert flash to confirm the wireless link it working. It does nothing on the GPSmirror or C100.

The lead is an override cable that can be connected to the corresponding cable on the LASERnode transmitter from the Laser Jammer Interface. When connected this is a fail-safe priority override for jammer alerts. If you are not using a Laser Jammer Interface, please just ignore this cable.
