Reply and solution:

Hello friend, This is Amy, I received your question about sound and steering wheel control. Really sorry for the inconvenience, that problems happened because of the wires were connected wrong. Here are the solutions, please check: 1. Steering wheel control Please check the attachment, that "pink" wire is for steering wheel control, the second image is right connection, could you please check and correct it? 2. Can't hear when Bluetooth calling Please watch this video: -gray wires and white wire---front speaker wires -purple wires and green wires---rear speaker wires As you can see the video, we exchanged the position of front and rear speaker wires. Could you please unplug and reconnect the wires? And if this can't solve the issue, please e-mail me again. I also added two pictures related to the details of the speaker wires. Thank you so much.

Easily solve if you get an exclamation mark when start Joying head unit

Problems from Joying customers:

1. The screen only shows an exclamation mark
in a yellow diamond whenever it's plugged in.  I spent hours trying to fix
it, but the radio plug appears to have a missing part to it, and the
exclamation mark won't go away even after multiple tries of reboots and
resets.

2. When I put my car in reverse there is an exclamation point instead of the image.  Can you help?

Analysis of causes: Connection error

As the images above, when the "back" wire was applied to the power, you can see an exclamation point in screen, and it will be normal when you disconnect power.

Solution:

1. The "BACK" wire is used for connecting triggering wire of backup camera. 

     

More detailed info, please read this blog:  https://www.carjoying.com/Joying-blog/7.html

2. If your car has can-bus system, please disconnect the "BACK" wire.

Because the can-bus will decode the reversing image to Joying head unit. (You need to buy a proper can-bus decoder for your car)

Please find the "BACK" wire in the harness, it is an Orange wire. (Not orange+white or orange+black)

Please the "BACK" wire
