Nightmare. After having the Carsifi for some months, I got out of the car and got some shopping, got back in and have never been able to get the damn thing to connect again! I am now wondering if it was a waste of money. The firmware states it is up to date. I drive a 2017 Audi A3, and use a Oneplus 8 Pro. I have turned the AA intercept on and off half a dozen times. I have refreshed, reloaded the Carsifi software, and tried to reconnect everything. Nothing works. It goes through the connection process with the lights flashing then solid green. My phone beeps a connection with Android Auto and says to use the car screen to operate Android Auto but nothing! The car screen is a blank.
Nothing I do works.
When I plug my phone into the USB port, it connects to Android Auto in a second.
