Dasaita Unit Buzz causing headaches

Hi all. Anyone else had buzzing/whining from a dasaita 10.1 unit. I read somewhere the wifi antenna can cause it, removed it but its still there. I have not connected the ground cable yet its very short and I don't know where to put it. The noise is so bad it causes me to have a headache and need to shut thr system off.

 

Did you attach the black ground in the aftermarket harness? Others have had issues with buzzing when the ground is connected. I did not use the additional ground in the aftermarket harness and have had no buzzing.

 

The ground cable coming from the headunit is very short so I just covered it up with electrical tape
