Cobra iRadar Review

Using it and Performance:

Using the iRadar as a standalone radar detector, we’re actually amazed to find it performing exceptionally well in digging out various radar systems. Even though we don’t find any visual alerts on the actual unit itself, the iRadar emits variable tones to indicate the presence and distance of a specific radar. Additionally, a voice will announce what kind of radar band it’s picking up – like X, K, Ka, and VG-2.

However, the iRadar shows its true potential when it’s paired with a compatible iOS  or Android device (iPhone 4 in our case), and the free Cobra app. Running the app on an iPhone 4, the interface is mainly straightforward with its finger friendly sized icons – and we like that it’s not too complex to operate. Basically, the iRadar sends alerts to the iPhone 4 to visually notify you what it’s picking up, records GPS markings of each alert, and utilizes the GPS location to notify you of any speed traps or red light cameras.

Getting into Dashboard mode of the app, it’s considered to be the center of operation for the entire iRadar system. Specifically, it displays items like our current speed, car battery voltage, and direction that we’re heading. Obviously, when the iRadar detects something, it’ll display what it is specifically, and from there, we have the option of choosing whether or not it’s actually a real or false alert. Needless to say, this function proves to be valuable seeing that it records the location of the alert – so that we’re aware of any common false alert areas. Additionally, you can also manually mark a specific location to the handset if it appears to be an area of high enforcement.

Using the iRadar over the course of a week, we’re actually impressed by its usefulness in keeping us aware of our surroundings. Not only are we alerted to various threats, but it’s nice to see that Cobra’s database is extensively updated to give us the most accurate alerts for speed traps and red light cameras. However, if there’s one thing we’d love to see integrated, it has to be another alert for speed limits – like being alerted by the app if we’re speeding above the limit.


If you haven’t shopped around for a radar detector of late, you’ll naturally find some basic ones priced at under $100, but for ones that incorporate more location based features, you can expect them to be placed above the $200 mark. Sporting a reasonable $129.99 price tag on the average, Cobra’s iRadar is indeed a venerable companion to the iPhone – mainly because of its intricate functionality in sniffing out and saving alerts. At the same time, we’re better able to drive normally without being distracted because the iRadar is able to announce alerts and emit variable tones to indicate the presence of a particular alert. Honestly, it’s not all about being one step ahead of authorities, but rather, the iRadar allows us to be better informed of our surroundings.

Great news story. I think this is the perfect web site for the story and it looks like an great devise. "Box" if you read the article, it is not a standalone radar detector but works only with a compatible phone. I hope you add other news stories that are directly connected to smartphones. Thanks.

I would like to see speed limit alerts as well, it would be great when travelling to a new city and your not familiar with the stretch of road that suddenly drops the limit by 10 mph. This is the kind of implementation that finally gets me to buy a radar detector.

Sounds great, but can you use this and also use your iphone or android for directions at the same time?

Don't waste your money. I wasted FF miles as they were about to expire. My purpose of getting this device was simply to get an alert from the motorcycle police pointing their radar device at me while on the 71 freeway and Yorba Linda blvd which is almost a daily occurance. Until I had the opportunity to test it with an actual motor cycle cop pointing his radar gun at my car the device did sound off all X alerts (no use to me), and K alerts when I drove past the speed signs displaying your current miles per hour. It sounds off K and KA alerts but I don't see a police car anywhere. Finally I had the opportunity to test it with the motorcycle cop pointing the radar gun at my car two mornings back to back and it didn't make a sound at all! There's no reason to believe it's defective. Brand new unit and i can't return it because I used FF miles to purchase. Very dissapointing. Guess I have to find a real radar detector on the market and buy that one.
