G'Day all from Sydney,Australia:
I am the proud owner of the all new 370Z,only just arrived in Australia just weeks ago.
Unfortunately,I too have the same high pitched noise that some of you guys are experiencing
NOT HAPPY!!...the bomb I traded didn't cause me a head ache to drive!!!
I can also confirm that the noise is coming from under the glove box.I know it is not the radio,speakers, GPS, air con., mobile (cell) phone.My Z is auto, right hand drive.Nissan are checking it out tomorrow.Thanks to this site,I know I am not the only one with this prob.Lets hope we can all get it sorted with out too much hassel.
