Do not email yamaha from there Web pages "contact us" link. Someone is steeling the information from the form you fill out. I was hit and have been getting endless emails and phone calls from spammers.
We had an I.T guy here to try and figure it out. In the list of pages I gave him that I contacted he said the yamaha pages when he looked into them (not computer savey) (don’t know the terms) but info is being stolen from there pages
