Can you add blind-spot monitoring after purchase?
Yes. In many cases you can add blind-spot monitoring after you buy a car, either through an official dealer retrofit or a reputable aftermarket kit. Availability depends on your vehicle’s make, model, year, and existing safety electronics.
Options for adding blind-spot monitoring after purchase
OEM (dealer-installed) retrofit
Some carmakers offer official retrofit packages that integrate with the vehicle’s safety systems. These options are designed to work with your car’s existing controls and displays, and are typically performed by a dealership or authorized service center.
- Compatibility varies by model and trim; not every vehicle is eligible for an OEM retrofit.
- Hardware often includes new sensors (radar or cameras), a control module, wiring, and possibly updated mirrors or dashboards.
- Calibration and programming are performed by technicians to ensure accurate detection and proper warnings.
- OEM retrofits are typically backed by the manufacturer’s warranty, and parts are usually OEM-approved.
- Costs and installation time can be substantial, ranging from a few hundred to several thousand dollars depending on the vehicle.
If you’re considering this path, contact your authorized dealer to confirm model eligibility, price, and timeline before committing. A dealership could also confirm how the retrofit interacts with other safety systems like cross-traffic alerts.
Aftermarket blind-spot monitoring solutions
Aftermarket options provide more breadth in price and installation approaches, but results can vary. These systems range from simple kits to more integrated solutions that mimic OEM behavior.
- Radar-based or camera-based kits can be mounted on the bumper, fenders, or mirrors and wired to the vehicle’s power and illumination circuits.
- Many aftermarket systems offer indicators in the side mirrors or instrument cluster, plus audible alerts when a vehicle enters the blind spot.
- Installation complexity varies; some kits are designed for DIY installation, while others require professional installation to ensure proper placement and calibration.
- Calibration is critical; improper setup can lead to false alerts or missed detections, especially at higher speeds.
- Warranty and insurance implications vary by brand and installer; aftermarket work can affect your vehicle’s warranty in some cases.
For those choosing aftermarket, seek brands with solid reviews, clear installation guidance, and a reputable installer. Confirm that the kit supports the same alert modalities you want (mirror lights, dashboard indicators, or cross-traffic features).
What to check and how to proceed
Before pursuing a retrofit, take a structured approach to ensure you get a safe, reliable result that fits your vehicle and budget.
- Verify model compatibility and whether your car supports an OEM retrofit through a dealer.
- Decide between an official OEM retrofit (often higher cost but greater integration) and an aftermarket solution (more options, variable quality).
- Obtain written quotes for parts and labor, and ask about warranty implications for both OEM and aftermarket routes.
- Ask about calibration procedures, required software updates, and whether the system will work with other safety features you already have.
- Choose a reputable installer if going aftermarket; ensure technicians are trained on your vehicle and the specific kit.
- Test the system in a safe environment after installation to confirm reliable detections and alerts.
By taking these steps, you can add blind-spot monitoring in a way that maintains safety, preserves warranty where possible, and fits your budget.
Summary
Adding blind-spot monitoring after purchase is feasible for many vehicles via OEM dealership retrofits or reputable aftermarket systems. The best option depends on model compatibility, cost, warranty considerations, and your tolerance for installation complexity. Always verify calibration and test the system to ensure it operates reliably, and consult a trusted technician or dealer to avoid compromising safety.
How much does it cost to add blis to a car?
The total cost for aftermarket blind spot sensors, including professional installation, typically ranges from $450 to $1,000. The sensor kit itself costs between $250 and $500, with installation adding another $200 to $500 depending on the system's complexity and your vehicle.
Can you add blind spot monitoring to a Wrangler?
Blind spot cameras can often be integrated into your Jeep Wrangler's infotainment system or dashboard display.
Can you add safety features to an older car?
Yes, you can add modern safety features to an old car through aftermarket systems, such as installing a backup camera, blind spot detection, or a forward collision/lane departure warning system. You can also add an emergency assistance device like OnStar or a similar product that automatically contacts emergency services after an accident.
Types of safety features you can add
- Backup camera: These systems can be added to the rear of the car and send a wireless video feed to a monitor, which may be a separate screen or an upgraded rearview mirror.
- Blind spot detection: Sensors are installed on the sides of the vehicle to monitor blind spots and alert the driver with a visual cue on a side mirror or a separate display.
- Forward collision and lane departure warning: These systems use cameras to monitor the road ahead and will alert you if you drift out of your lane or if a collision is imminent.
- Emergency assistance: Devices like Hum by Verizon can be installed in cars built in 1996 or later and can automatically call for emergency services if an accident is detected.
- Tire pressure monitoring: Sensors can be attached to the tire valve stems and transmit pressure data to a base monitor or a smartphone app, alerting you to low tire pressure.
Important considerations
- Cost: Research the cost of both the equipment and installation. Compare the total cost with the option of buying a newer car.
- Aftermarket system quality: Read reviews of aftermarket systems to ensure you are purchasing a quality product.
- Professional installation: Consult a trusted mechanic for recommendations and installation to ensure the system is installed correctly and safely.
- Insurance coverage: Check with your insurance provider to see how aftermarket parts are covered in case of an accident. You may need to add specific coverage for the new equipment.
How much does it cost to add blind spot monitoring to a car?
Adding blind spot monitoring can cost anywhere from $200 to over $1,000, depending on whether you choose a DIY kit or professional installation, and the features you want. Basic aftermarket kits cost about $75-$300 for the parts, while professional installation will add at least another $200-$300, with high-end, factory-like systems costing up to $899-$1,199 or more installed.
Cost breakdown
- DIY Kits:
- Basic Kits ($75-$300): These are the most affordable options, often using ultrasonic sensors. They are generally less accurate than higher-end systems.
- Mid-Range to High-End Kits ($300-$500+): These systems use radar and offer better accuracy and features, like rear cross-traffic alert.
- Professional Installation:
- Basic installation adds at least $200-$300: to the cost of a DIY kit.
- High-end systems with features similar to factory-installed options can cost between $899 and $1,199 or more: when professionally installed.
- Factor in the type of system:
- Basic ultrasonic systems: Cheaper, but shorter-range and less reliable, especially in bad weather.
- High-end radar systems: More expensive, but offer longer range, higher accuracy, and more features.
What affects the cost
- System type: The technology used (ultrasonic vs. radar) significantly impacts the price.
- Installation method: Do it yourself, or have it professionally installed?
- Additional features: Does the system include features like rear cross-traffic alert or on-screen displays?
- Vehicle compatibility: Some vehicles may require more complex installation or specific kits.
