I just bought a 2007 Nissan Sentra 2.0 S 2 weeks ago. The clock is off by a couple of minutes and it bugs me. I have read online that to change the clock you hold the clock display button and the clock will flash when ready to change the time. When I hold the button nothing flashes and the clock doesn't do anything. It's like the button doesn't work. The same thing goes with the mix rpt button, nothing happens when pressed or held. Anyone have any solutions to this problem?
