Installer App

Installation of Rosco products requires the use of the Rosco Installer App to ensure proper setup and configuration. If you do not already have the app installed, scan the QR code with your mobile device and select either iOS or Android to download the Rosco Installer App.

If you already have an existing account on RoscoLive, you can use these credentials to log into the app. Please note that only certain users can actually perform installations into your company - so if you do not see the "Install" option available to you, create a new set of credentials by tapping "Sign Up" on the login screen. Additionally, RoscoLive only allows 1 set of credentials to be associated with an email account so you can either use a different email to make the credentials OR create an "alias" email account by entering your email like the following:

                     [your normal email prefix]+installer@[your normal domain]

ex: If your normal email address is: john.doe@example.com - then your alias email will be: john.doe+installer@example.com

🛠️ Installation Steps

Once you have confirmed that all required tools and components are available, you are ready to begin the installation. You may follow the instructional video below or use the detailed step-by-step written instructions provided in the following sections.

Installation Video

Step 1. Mounting Location

a. Camera should be mounted as close to the center of the windshield as possible. If the windshield has a center divider, mount the camera as closely to the driver's side as possible without obstructing the view of the driver. (Fig. B)

Step 2. Prep Windshield for Mounting

DV7 ON WINDSHIELD_page-0001

  • Keep the camera lens within 8.5" below the tips of the windshield blades.
  • The camera lens MUST be within the wiper pattern to ensure proper visibility.
a. Clean mounting area with alcohol wipe. (Fig. C)

DV6 QSG Alcohol Wipe
Fig. C

b. Coat the mounting area with the primer pen and let dry. Proceed with the install while letting the primer cure for 5 minutes. (Fig. D)


DV6 QSG Primer

Fig. D
 

It is important to let the primer properly cure for 5 minutes before mounting the camera. Failure to do so will result in an incomplete bond with the adhesive pad which will lead to the camera falling off the windshield during operation.

Windshield temperature needs to be at least above 50ºF (10ºC) for proper curing and adhesion. It is recommended to apply a heat gun to the mounting area or turn on the vehicle's defrost prior to applying primer to ensure proper glass temperature. 

Step 3. Prep the Vehicle

a. Loosen the panels as needed to allow routing of the wiring. (Fig. E)

b. Remove the panels beneath the dashboard and around the steering wheel/column to access the OBD-II or J-BUS connections and the yellow ignition (IGN) wire. (Fig. F)

FOOTNOTES

  • If you are completing the installation using a partner’s installer app, refer to that app’s documentation for specific instructions on installing a Rosco product.

Please note that this guide is a living document and is subject to change. As we continue to gather feedback from installers and fleet operators, refine our procedures, and introduce new hardware or software features, we will update these instructions to reflect the most accurate and effective installation practices. We recommend reviewing this guide online prior to each installation to ensure you are working from the most current version.
