For about 2 weeks, the navigation screen and the stereo have been stopping and restarting randomly. The screen will go black and the stereo will shut off. The screen will then reboot as if I just turned the car back on. If I turn off the car after it's done this on a drive, the car won't turn back on and I won't be able to lock the doors with the fob. The car will then be working fine minutes later.

I replaced my battery in October of 2019, so that shouldn't be the issue. Has anyone dealt with this before? Is it something I can figure out myself or do I need to take it to a professional?

thanks in advance
