Well I got the new replacement headunit in but a few issues
diagnostics screen are all in Korean and I don’t know how to fix it
backup camera doesn’t show on screen but it will in diagnostics
USB stick shows on screen but I get USB error
buttons on the side do not light up at all even with the headlights on
will not connect to Bluetooth even though the car is in park as it says the car must be stopped to use this feature. Will try again with the ebrake on
Plus side
The volume and steering wheel buttons do work
