Rear Parking Sensor Retrofit for Mercedes Vito/Viano/Valente 639

Description

Rear Parking Sensor Upgrade for Mercedes Vito / Viano / Valente 639

Make reversing your Mercedes Vito, Viano, or Valente 639 easier and safer with this rear parking sensor retrofit. Because these vehicles often operate in tight driveways, shopping centres, loading areas, and busy urban spaces, judging the distance behind the vehicle can be difficult. This system helps solve that problem by giving you clear audible warnings as you approach obstacles.

The kit uses four ultrasonic sensors mounted neatly into the rear bumper. In addition, the sensors are colour coded to match the vehicle, so the finished look remains clean and discreet. Although this is not the original factory Mercedes system, it still delivers practical, OEM-style parking support that improves confidence and helps reduce the risk of reversing damage.

Whether you’re backing into a parking bay, reversing out of a driveway, or manoeuvring in a crowded area, this upgrade gives you a more accurate sense of what’s behind you.

How It Works

The system activates automatically as soon as you select reverse gear. Once active, the four ultrasonic sensors begin scanning the area behind the vehicle and measuring the distance to nearby objects.

As you move closer to an obstacle, the buzzer sounds an audible warning. At first, the beeps are slow and spaced out. Then, as the gap becomes smaller, the beeps speed up. This progression helps you judge distance more accurately and react sooner while reversing.

Because the system uses audible alerts, you don’t need to look at an additional screen. Instead, you simply select reverse, listen to the warnings, and manoeuvre with greater confidence.

”Integrated Automotive Electronics Solutions”

Integration

When dealing with automotive electronics products, it is important to maintain the original characteristics and functionality of each vehicle, and that safety and aesthetic aspects are not compromised in any way. At Autofidelity, we call this integration. This solution is available for Mercedes vehicles. For more integrated solutions, check out our Mercedes solutions page.

Expertise

Autofidelity is renowned for employing the highest quality techniques and technicians, using the highest quality standards in the automotive electronics industry.

Most people can be forgiven for thinking that all parking sensor systems are equal, but are they?

It is important that every aspect of an installation of a Park Distance Control System meets the highest standards to ensure that the product operates for years to come, and doesn’t detract from the visual appeal of your Mercedes, however there are many aspects that are often not considered. Here are some examples:

Colour Coding

The process of colour coding each sensor is not unlike the process used to paint your car. This is essential if the sensors are expected to retain the same standard of finish as your car for years to come.

Each sensor is prepared for painting using a special abrasive material, then cleaned and masked. The sensors are then inserted into a specialized painting jig ready for painting.

Paint colours are mixed according to manufacturer paint code and specifications using the Glasurit painting system to ensure a perfect colour match every time.

Each sensor is painted with 3 base coats and then 2 clear coats. The sensors are then baked in a professional, purpose built paint finishing oven.

Wiring

Unfortunately, it is often the things that we don’t see that can make a difference. Inferior quality or poorly installed wiring can cause thousands of dollars in damage in extreme cases. In minor cases, wiring can even cause annoying rattles. Our systems are supplied with wiring harnesses which are wrapped in fabric insulation, conforming as closely as possible to the wiring standards set by the manufacturer and ensuring that there are no annoying rattles

Warranty

This product comes with a minimum of 12 month manufacturers warranty and if installed by Autofidelity Australia we offer a lifetime warranty on our installation.

Diagnostics Check

As a standard part of our installation process we carry out a pre-installation and post-installation diagnostic check on your vehicle. This allows us to ensure we do not incorrectly code or leave any components unplugged in your car. As an added bonus if there any existing faults in the vehicle we can identify and advise where it is. Having your vehicle properly diagnosed is a vital step when fixing faults to help reduce the chances of big unnecessary repair bills. If you are not having an installation done we can offer this service for a flat fee of $165 to perform the diagnostic check.
