Dash is a partner app designed to work with Vinli. If you have any troubles with Dash, first check to see that your Vinli device is properly connected.
Make sure you have firmly plugged your Vinli device into your OBD-II port. Turn on your car and wait 30-60 seconds or until you hear a beep from the device. If you hear a beep, open the MyVinli app and check the connection under the Main Menu. There, you can check connections for GPS, WiFi, LTE and Bluetooth (Android only).
If you are still having trouble, please review support articles provided on Dash's website.
