Radio/tape Cd Player problems of the 2014 Nissan Rogue

I was driving at about 75 mph in va on hills when the lights on the dashboard blacked out. I could not see the rpms, actual speed I was going as the speedometer and central panel that displays the mileage drive were all black. I started to panic thinking the car had just shut down - I cannot recall if the radio panel was also off. My instinctive response was to step on the gas to see if the car was running to which I felt the car speed up but I still could not see anything on the dash. I subsequently pulled over and shut off the car. The dashboard lights and readings were visible when I started up the car. In hindsight, the dash had appeared to flicker earlier in the drive but I thought it was just my visual angle from looking down through my bifocals. I reported it to my dealer to have it checked under warrantee. The dealer's staff noted they could not recreate the problem and noted to bring it back when the problem was occurring, if it recurred. Not sure if they really tested it as the maintenance was done in less than two hours which also included an oil change and tire rotation.

I have qty 2, 2014 Nissan Rogues, both have the $1420 navigation system and neither of them work. The directions are not accurate and can be off by miles, or just out of the area altogether. It will not display sub streets and just tells you to get to a main road. The nav, radio and control module reboots often. I have had the dealer look at it and in one of them they upgraded the maps data file, this did not help. I do not use the navigation at all and have resorted to my old garmin, windshield mount, which works perfectly. Nissan should have just embedded a garmin in their dash. Total waste of money 5n1at2mtxec794681 & 5n1at2mt9ec818386.
