Getting Started


  • First, you must purchase and install a CANserver in your tesla, if you want blind spot monitoring you will need the dual bus Tesla version.
  • Please update your CANserver to Version 2.1 of the firmware. Easiest way is to connect your canserver to your home wifi and using a desktop browser to “check for updates” in the CANserver webui.
  • Two options for running this app, either connect to the hotspot on the CANserver (you will lose internet connectivity, even with mobile service) or create a hotspot on your phone and connect the CANserver to it via the network settings tab.
    • Turning on hotspot functionality on your phone is preferred if you want to use cloud connected apps like music and nav simultaneously
  • Sideload the app to your phone, it will appear as ‘CAN Dash’
  • Launch the CAN Dash and long press any blank area on the screen to bring up the info pane. 
  • Once you are sure you are connected to the CANserver, click ‘scan’ and if the phone and CANserver are on the same network, the IP address should auto populate and you should start seeing data appear on the right side of the screen. Once you see this, press the ‘DASH’ button to start the dashboard.
  • If you do not plug in the phone it will follow your display preferences for sleep and time out. If the device has power then it will keep the display on with any auto-brightness you have enabled.
  • Recommended device: So far the best device we have tested is the Google Pixel 2 XL, running Android 10. We like this device because it supports all the standard Google tools that allow for auto booting when plugged in and off, it has a beautiful OLED display with no holepunch camera that is particularly stunning at night, and it is relatively inexpensive used.

Dash View

  • This screen should work without any user interaction required.
  • Tap the speed units (MPH or km/h) to toggle the performance gauges
  • Power meter on the bottom has max regen on the left and max power on the right, tap either to reset, like an odometer. Tap the center to change units from kW to HP
  • Long press center power display to hide/show max/min
  • Tap the battery to change range from percent to distance
  • Tap speed to force night mode on, otherwise it will copy what the car does
  • Blind spot monitoring is based on the ultrasonic sensors in the rear bumper, as the car does not return any blind spot data from the cameras unless the turn signal is on. 
  • If you turn on your signal and the car sees a car in your blind spot, the background of the dashboard will turn red
  • If the phone is plugged in the screen should never turn off- let me know if it does

Auto launch

  • If you want to use this on a device that is always in your car, consider installing Tasker. With Tasker you can have the phone automatically turn on the hotspot when plugged in or connected to vehicle bluetooth, and turn off the hotspot when the phone is unplugged (if you have it plugged into your car, this will happen when the car sleeps)
  • To have the phone power on automatically when plugged in, use this fastboot command: fastboot oem off-mode-charge 0

Known issues:

  • If you switch between split screen and full screen while a door is open, the UI gets unhappy. Either restart CANdash or go to the info screen and relaunch the dash view to reset.
