How much does a blind monitoring system cost?
Do you have a first- or second-generation Mazda 3, and you’re wondering how much it would take to install an aftermarket blind monitoring system on these models?
A blind monitoring system has two main components. The first component is responsible for detecting the presence of cars on blind spots. The second component is responsible for getting the driver’s attention and notifying them of any approaching cars.
The most affordable aftermarket blind monitoring systems cost around $250. However, these systems are severely limited in functionality and sometimes even accuracy. These systems include a few sensors and only the very basic indicator technology.
The midrange price of blind spot monitoring systems is in the $500 range. These systems have better accuracy, although they are still less accurate than factory-installed blind spot monitoring systems.
The most accurate aftermarket blind spot monitoring systems use advanced algorithms that greatly reduce the possibility of false triggers. Additionally, sensor accuracy is high. These systems cost more than $500.

Where are the BSM sensors on a Mazda 3?
Now that we’re done talking about each year's model versions, and trims that offered BSM either as a standard feature or option, isn’t it interesting to know where the BSM sensors are installed?
There are two radar sensors installed on both the Mazda 3 Sedan and Mazda 3 Hatchback model versions. They are located on the rear bumper, with one radar sensor on each side.
Why is my blind spot monitoring system unable to detect vehicles?
The BSM system needs to meet certain conditions before they alert the driver even though there is a vehicle within the monitored area of your Mazda 3.
The following are some of the conditions that can cause the blind spot monitoring system to ignore a vehicle.
- The vehicle within the detection area is not approaching your Mazda 3.
- The vehicle driving alongside your Mazda 3 is moving at a similar speed.
- The vehicle within the detection area is traveling in the opposite direction.
- The vehicle is driving in an extremely wide adjacent lane.
- The vehicle’s speed is below six miles per hour.
- There is a high difference in speed with vehicles in the monitored area.
- The vehicle is small, like motorcycles or vehicles with a very low height.
- Your Mazda 3’s speed is slower than seven miles per hour.
How do you turn on the blind monitoring system in Mazda 2019?
Your BSM system is off when you see the light that says “BSM Off” in your dashboard instrumentation cluster.
Look for the BSM switch to turn it on. Once it turns on, the “BSM Off” light will go away.
How to adjust BSM alert volume?
The BSM alert volume can be changed from the home screen.
- Go to “Settings” on the home screen.
- Choose the “Safety” tab.
- Select “Blind Spot Monitoring System.”
- Adjust the volume accordingly based on your preference.
You can choose to turn off the volume of the alert. This will mute the beeping alert, but the light signals will still be active. They will light up and signal you as normal when there is a vehicle on the blind side of your Mazda 3.
The Ampper 2" Blind Spot Mirror can show you objects near the vehicle. See it on Amazon.
The blind side monitoring system is an important safety feature that can prevent inattentive drivers from changing lanes into an oncoming car.
Knowing which year model, version, and trim have blind side monitoring is important to know before purchasing a Mazda 3.
