There are many opinions on where to mount a radar detector. Some drivers say that it should be mounted high by the rearview mirror or at the top or middle of the windshield. Others say it should be mounted low on the dashboard with suction cups. With that, it can get confusing on where to place your radar detector. There is no clear single answer, and you have several options to choose from.
One of the most common places to put your radar detector is low near the dashboard if you have a suction cup mount. This will give you optimal visibility and safety when using a radar detector.
With that being said, if you decide to mount it on your windshield, place it somewhere that it will not obstruct your view. For instance, place it right above your rear-view mirror. You can also purchase a rearview mirror mount for another installation option.
Note that in some states, there are specific laws on where you can legally place the detector. With that, make certain that it is not illegal in your state to suction a radar detector to your windshield. Check with your local state laws to be certain you have legally mounted your radar detector.
In short, the most common places to put a radar detector are low on the dashboard, mounted below the rear-view mirror, or high on the windshield so as to not obstruct the driver’s view.
