I will try again and do it the way you say...methodically. A dealer screen came up before....let you guys know.Be sure you are holding down both the right side up and down temperature buttons down, then press the tune button six times and release the temp buttons. I did it methodically, like maybe 1 press every second and it worked first time. If you're pressing the tune button really fast maybe try slowing down.
Thank you for such a fast response!
