Cobra - RAD 490i Radar and Laser Detector, works with Apple CarPlay/Android Auto - Black

This Cobra radar detector is a full featured bargain. I have been out of the radar detector game for a while but I never would have stopped using one if the one I had could do everything the RAD 490i does. DESIGN: It looks like most radar detectors, a sleek black plastic box with a cable coming out of it. This one is a bit different than what I am used to though because it is USB-C which is fantastic because it is the most universal way to connect power to any device. Pretty much everyone has a laptop, phone, tablet, razor, monitor, mouse, keyboard or a hundred other devices that charge, are powered by, or otherwise connected via USB-C. This means everyone has a spare cable or twenty. No more proprietary cables and you are also not limited to a 12v port in your car to power it. Most new cars have USB-C connections and most that don’t have the older USB-A. It also uses an OLED display which is really easy to see even on the sunny days I’ve used it for the past week and a half. I’m not sure if I love the mount for it. On one hand it is great because you can easily remove the RAD 490i from the mount but the mount has 3M permanent adhesive. That means it will stay where you put it but also means you need to make sure it is perfectly level when you install it. If you’re a bit OCD like me it will really bother you if it is not level. I wish there was an option for the old suction cups or a 3M removable adhesive. USE: As I mentioned, I’ve used this for about a week and a half and I really like it so far. I thought using the menus to adjust settings was going to be difficult but it was actually quite easy. The volume is quick to adjust since they kept the dial! I love the dial because that is probably the adjustment I make the most while driving and it is simple to operate. It’s the only dial and you know exactly what you are doing without looking at it. There are three different levels for detection as well. This is nice because if you are in a city setting it may go off all the time so you can adjust it to be less sensitive to non-police radar it may pick up The app adds a whole new element to radar detectors. Using the app in Android Auto or CarPlay is awesome. It’s kind of like Waze for Radar! The app is also very easy to use. Overall I could not ask for a better radar detector. I’m also not sure what I would do with more features. I absolutely recommend this for anyone new to radar detectors or for those that just want something simple that works well.

Back in 2012, I purchased my first Cobra radar detector. Back then, cars didn't have the sophisticated blind-spot detection, lane-assist, and adaptive cruise control systems they do now. Today, the RF environment is incredibly jammed—modern cars constantly trigger false alerts. To correctly use the Cobra RAD 490i, you need to educate yourself on radar bands and how police speed devices actually work. You have to learn how much reaction time you actually have once a signal is detected. Be warned: if you catch a laser signal and you are speeding, you are pretty much done. Laser is highly directional; by the time it triggers the Cobra, you have already been targeted. The Good: It is lightweight, looks stylish, and the new windshield adhesive mount with the static sticker completely avoids accidental detachments. Moving to USB-C is a huge upgrade. Most modern cars have USB outlets now, and using my USB meter, I verified the current draw is low (under 500mA). It’s robust and universal. The Drive Smarter app works well for me, especially since I use it for both my Cobra dash cam and this RAD 490i. Speed traps pull up directly on the screen, and the in-dash smartphone integration is solid, though I did find the Bluetooth connection a bit spottier on one of my mobile devices compared to the other. The Bad: I really expected Cobra to include an onboard GPS chip at this stage. Having internal GPS would allow the device to handle its own low-speed muting and perform GPS lockouts to ignore fixed false alerts (like grocery store automatic doors). Instead, you are entirely reliant on your smartphone app to do this heavy lifting. In conclusion: As an introduction to the radar detector world, the RAD 490i is a good start. The features added by your phone essentially boost your Cobra's capabilities. Cobra is a reliable brand—my 2012 model is outdated, but it is still kicking. This is a good device to let you know what is going on around you, but it is not a foolproof ticket preventative device if you want true protection without the hassle of constantly linking your phone.

It’s sort of hard to review a radar detector because you never really know for sure how well it works until you’re in a situation where you needed it to and then it either did or it didn’t. During my audition of the RAD 490i, I was never laser-checked, but there were a few X-band and K-band speed traps that I WAS alerted to and could later verify; so, in that sense, the early warning the 490i promises definitely delivered. If that’s all you need or really want–or can really afford–then this unit is probably going to do you VERY well. And given that the asking price puts the 490i very near the low-end of the pricing tiers available for Cobra and its competitors, I’d say you get a pretty good value for your dollar–just don’t expect it to WOW you with looks or extra features. The unit itself is small enough so that it doesn’t take up a huge amount of windshield space once it’s mounted. Strangely, Cobra chose to ONLY include a permanent, 3M adhesive window-mount in the box, which means you’d better measure several times before placing it, lest you finally get it on the window and realize you’ve got it tilted just a tad to the left or right. For some people, that probably wouldn’t even be an issue; but for someone with OCD-level obsession over having everything in JUST the right place, I would imagine this would be a little irksome (it would have been for me). I bought a cheap suction mount online so that I wouldn’t have to deal with finding the ideal mounting point and then committing myself to that location forever (or until I destroyed the existing adhesive and bought some new 3M adhesive), and so that it was a lot easier to move the detector from one vehicle to another. The unit has a USB-C port and comes with a low-profile 12V USB-C plug-in adapter and a fairly long USB-C to USB-C cable for connection. The cable itself will likely be enough for you to place the detector anywhere on the windshield you want, but having a coiled cable would have been appreciated to help keep all that extra cable from dangling down into my center console or flopping into the passenger seat. You can use the 12V adapter or plug the detector directly into the head unit of your vehicle if you have a USB-C data or charging port. The type of USB-C connection (charge or data) doesn’t really matter because it’s only used for powering the detector anyway. The marketing materials indicate that the 490i is CarPlay/Android Auto enabled–and that is true in a manner of speaking. It’s not that the 490i works DIRECTLY with your vehicle’s CarPlay (or Android Auto, I would assume). Instead, it integrates with the Drive Smarter app which DOES speak directly to the vehicle. Once you have Drive Smarter installed on your phone, it syncs via BT to the 490i and reads, speaks, and displays speed and detection information onto your in-dash video screen. It’s definitely a nice feature to have as more and more vehicles are coming equipped with at least one USB port. The only drawback, of course, is that you have to run with Drive Smarter open for the integration to work; this may be an irritant if you routinely use Apple or Google maps to plan your routes or provide in-vehicle navigation. There are a number of options and operational settings you can adjust directly on the unit itself, but the Drive Smarter app not only gives you detection integration, it lets you adjust a multitude of settings on the detector via simple toggles on the phone’s screen which I much preferred to using the awkward 4-button navigation system on the top of the unit itself. When not integrated into your vehicle’s in-dash display, all information is also available on the TINY screen and via audio feedback from the detector itself. The display is nothing to write home about, but Cobra did a good job of keeping it simple, easy to see, and attention-grabbing when you need it to be. In normal operation, the screen is black with high-contrast, easy-to-read white lettering and icons. Even at its brightest, it is much easier on the eyes than the harsh LED displays these devices used to have. Vocal prompts like operating status are spoken rather than communicated via beeps or tones. BUT, when a detection is made, the screen goes from all black to all white, and the detection band, exact frequency, and signal strength is displayed in bigger, high-contrast white block characters and a 5-segment signal strength meter. A spoken voice prompt will also alert you to the band the signal was detected on. I don’t know if the improvement in reaction time would be measurable if the display didn’t change illumination schemes, but it’s a nice departure from the same-old readouts no matter what is happening with the detector. The biggest gripe I have with this particular model is that there are no directional indicators for the detections, so you can never be certain if the signal is oncoming, behind you, or off behind the trees on another road. Given that the 490i is more of a “starter unit” based on the price point, this little omission is probably forgivable, but it’s hard to get used to having a little less situational awareness when you’ve gotten used to another detector that does provide such information. We also have a pricey dashcam-radar detector combo unit. Driving with them both running, they both went off at roughly the same time and squawked at the same false positives due to storefront doors and vehicle avoidance signals; but overall, their performance seemed fairly comparable. If you are on a bit of a tight budget, the Cobra RAD 490i is definitely a solid choice for detecting radar and laser speed measurement signals early enough to avoid the cop at the other end–and as long as you aren’t looking for it to do much else, you’ll probably be pretty happy with it. Recommended.

I have used several radar detectors over several decades, dating back to the 70s. Cobra has always been a strong competitor in this field and this latest offering, the RAD 490i Radar and Laser Detector, is a good example why. However, this radar detector is not perfect. I’ll start with the shortcomings. The biggest shortcoming is the lack of any GPS to remember where the false alarms are located. I read that Cobra decided to not include it on this model in order to keep the cost down. I find having to deal with the same false alarms a bit annoying. My next complaint is that you have to use the Extreme Sensitivity to really get good advance warning of radar in patrol cars. Several times I physically noticed the police vehicle prior to the alarm going off. In my first week of use, only once was I truly alerted to radar I did not see or expect. It can be said that the one time alone pays for the unit - I won’t argue with that. The last negative is that the mounting tape they provided does not hold the weight of the unit. Where and how to mount a radar detector , especially one you prefer to take down and hide when not driving, remains a decades-old challenge. On the positive side, it does what it is supposed to do - alert a driver to the presence of radar or laser, whether it be from a speed gun or possibly an alarm system or other source. For the price point and - very important - my device included the subscription to the Drive Smarter app - avoiding one speeding ticket will probably pay for the device given the cost of fines nowadays. One last note, I would not consider an option which required me to pay to subscribe to the Drive Smarter app. Overall, it is a good radar detector, but as with most devices of this type, you will most likely have to put up with false alarms and an occasional failure to detect in time to avoid a fine, which prevents me from giving it 5 stars.

Setup was very quick. Plug into USB C or 12v car adapter, download the Drive Smarter app and add the detector to it. That’s it. Worked well with the default settings. It did go off quite a bit in town - likely some false positives from business alarms etc. I’ll probably play with using less sensitive settings when using in town, but mostly plan to use on highway driving. Highway driving works well. Only had one long road trip so far with it, but Feel like I always got alerted before I saw the cop. Once I saw 2 cops side by side on highway median but didn’t go off. Assuming they didn’t have their radar on. The drive smart app is easy to use and easily accessible in CarPlay. While you can do directions in the app I still prefer other mapping apps as this app doesn’t allow more than one destination/stop to be entered. The crowd source feature is nice to have but I don’t like taking my hands off the wheel to log incidents or police etc. Has loads of different detection types of laser, radar, bands, etc. The mute button is handy for silencing the alert until you’re past it. Note that speed signs that show your speed set it off, but makes sense as they re using radar. I like the non distracting minimalist cylon light that cycles back and forth and isn’t bright while it’s in its normal waiting to detect mode. The only con I’ll note is that it only comes with a sticking tape mount. It has a square electrostatic sheet that you can apply to windshield so that removal is easy, but we regularly drive through Virginia where these aren’t allowed and prefer a suction windshield mount to take down and put back up easily as needed. Fortunately they are inexpensive to add and many in the market that are compatible with the cobra line quick connector. Time will tell on detecting radar traps from a distance, but so far easy to use and setup.
