Our 2014 2.5 SL doesn't show MPH in the center menu either. I think Nissan blew that one big time. If you don't have the tech package, the first menu item showing the car is a total joke. That could easily be the MPH in numeric fashion.
Another point....
The dealer brochure shows the cruise control "Set Speed" in the bottom banner right side, but when actually setting or adjusting the cruising speed, it does not display that data. The center screen menu could easily display a lot of other data already available like coolant temp, oil temp, oil pressure, transmission temp, voltage, amperage, throttle position, and much much more. Just add one or two menu pages. It would cost nothing more than a little extra development time for a small software team to make it right, but the Nissan marketing team obviously had a "better" idea.
These 2013-2014 deficiencies could easily be remedied through a software update via the USB port.
The decision makers need a virtual frying pan impacting the top of their craniums. Come on Nissan....Wake Up! You ran a marathon extremely well but sat down with a foot to go to the finish line. Here I am with a 2014 and you still didn't move that foot over the line.
I hope one day Nissan will offer an affordable software update to this 5th generation Altima to make our driver information centers display all driver information. If their marketing team is smarter yet, they'll invite Altima owners back for courtesy update, charging something like $1 to avoid falling into the category of a recall. That would make huge news and promote the company immensely. But I don't think Nissan is wise enough to consider it.
I think most every Altima owner would pay the going 1/4 to 1/2 hour labor rate to have their DIC updated to display more useful data.....even if just for MPH.
