You'll have to go to Nissan's tech web site and pay to download the 2019 AV.pdf, which will have the new instructions to access the secret menu, if there is one.Bump for '19 and '20 owners. Has anyone found a way to access the menu on the '19's and '20's? The procedure mentioned above DOES NOT WORK on the later model vehicles. Works great on my '17 Maxima. With the Murano when rotating the volume knob while holding the menu button with the audio off only results in the radio volume increasing. I'm still looking for a solution but so far no go.
Here's the web site if you're interested.
Have a good day.
