Questions

Answers.

Everything else you need to know about Dot, from warranty coverage and returns to shipping, care, and ongoing support.

Installation & Power

What comes in the box?

The standard package includes:

- Dot display
- Control box
- Power cable
- Two display cables
- ATO fuse tap
- 12V adapter

Check that every component is present and undamaged before installation.

Do I need a professional installer?

A professional installer is recommended if you are uncomfortable removing trim, routing cables, drilling the trunk, or checking for factory wiring and cameras.

In what order should Dot be connected?

The connection order is important:

  1. Turn off and disconnect power.
  2. Connect both display cables to the Dot.
  3. Push each connector in firmly and confirm that its latch is engaged.
  4. Connect the display cables to the control box.
  5. Route and secure the cables so they cannot be pinched or pulled.
  6. Connect power to the control box last.
  7. Wait for Dot to boot before opening the app.

The control box may not boot completely if it does not detect the display and HDMI connection during startup.

What power source can I use?

Dot can use:

  • The included adapter connected to a vehicle’s 12V outlet
  • A USB-C source providing a stable 5V/3A

An unstable or underpowered USB source can cause slow loading, freezing, rebooting, or a blank display.

Can I use the 12V outlet in my trunk?

Yes. Use the included 12V adapter and confirm that the outlet supplies stable power.

How should the screen receive power?

The screen should receive its connection and power through the control-box setup. Make sure both display cables are connected firmly before powering the control box.

What drill-bit size should I use?

For installations that require drilling, support recommends a 5/8-inch drill bit (16mm). Inspect behind the drilling location first. Do not drill where factory wiring, cameras, release mechanisms, or structural components could be damaged.

App & Animations

Where can I download the official app?

- Dot for iPhone and iPad
- Dot for Android

Use only the official App Store or Google Play version.

Do I need to pair Dot manually in Bluetooth settings?

Normally, discovery and control should happen through the Dot app. If Dot does not appear, check the display connections and restart in the correct order before troubleshooting the phone.

Do I need to connect to Dot through Wi-Fi settings?

No Wi-Fi password or manual Wi-Fi connection is required. Use the official Dot app.

How do I check or update DotOS?

Open the Dot app and go toSettings → Version. Install any available update before troubleshooting performance or animation problems.

Can I upload my own animations?

Recommended video format:

  • Resolution: 480 × 480
  • Frame rate: 60 FPS
  • Format: MP4
  • Codec: H.264
  • Audio: None
  • Opening frame: Black
  • Closing frame: Black
  • Target: approximately 3 MB

For an animation pack, also provide:

  • A 1080 × 1080 transparent PNG cover image
  • A start animation moving from black into the pose
  • An end animation beginning from the same pose and returning to black

The final frame of the start animation should match the first frame of the end animation.

Troubleshooting & Support

Why can’t the app find Dot?

Dot may not appear in the app if the control box did not detect a functioning, properly connected screen.

Disconnect power, reseat both display connections, and power the control box last. Wait for startup to finish before trying the app again.

Why is Dot slow or freezing when switching animations?

Check the following:

  • The newest Dot app is installed.
  • DotOS is updated.
  • The correct power cable is being used. (USB-A to Micro)
  • The power supply can provide stable power.
  • Both display connections are fully seated.

If the issue remains, record a video showing the delay and send it to support.

Why does Dot have power but show a black screen?

Disconnect power and check the following:

  1. Both display cables are fully inserted.
  2. The connector latches are engaged.
  3. The HDMI cable is seated correctly.
  4. The display was connected before the control box received power.
  5. The correct power cable and a stable power source are being used.

Reconnect everything, then supply power to the control box last.

When is a replacement screen likely required?

Contact support if the display remains blank after:

  • Verifying the correct startup sequence
  • Reseating both display connections
  • Using the correct power cable
  • Testing stable power
  • Updating the app and DotOS

A screen fault can also prevent the control box from becoming discoverable in Bluetooth or the app.

What should I send when asking for technical help?

Include:

  • Order number
  • Vehicle year, model, and chassis code
  • Phone type and operating system
  • Dot app version
  • DotOS version from Settings → Version
  • Power source and cables being used
  • Clear photos of every connection
  • A short video showing the connection sequence and the problem
  • A description of what the control-box lights and screen do

Do not send passwords, payment information, or unnecessary personal documents.

What should the troubleshooting video show?

Show:

  1. Dot with power disconnected
  2. Both display connections being inserted firmly
  3. The connector latches
  4. The control-box connections
  5. Power being connected last
  6. The screen during startup
  7. The app attempting to discover Dot
  8. The actual flickering, freezing, or blank-screen problem

This helps support distinguish among a power, cable, screen, control-box, or software issue.
