My solution for squeeky dashboard noise
Found out the root cause for my car
i was so pissed, keep hearing it getting worse and worse,
it annoys me to the max
so i rage, took apart my panel. slowly troubleshoot and i found this.

If u see the photo above, not sure u can see it, there is a metal frame holding the dash,
the radio mount is rubbing onto the frame, hence creating the squeeky sound
so i took out the radio, saw the mount got some scratch marks, especially at the curved our area

took a playar, straighten part of bend, especially the place where it touch the body frame

used sponge tape to stick near all the screw mounts,
took apart the front panel, stick the tape in between there also

assembled everything back
no more squeeky, rattling sound the dash makes

great to see this! good job.
anyone out there tried this method? feedback to see if the squeaking noise resolved.
but. i had changed my head unit already, and while i installed, i'm think it wasn't touched the metal part, i still have squeaking noise. i will double confirm when i'm free.
