occasionally, I get an unexpected reboot, can't get BT to connect or some other such nonsense. It's a minor annoyance. But then my home pc, kindle, and yes, even my iPhone occasionally crash/reboot/freeze.
Many car stereos, including this one I believe, use some form of Windows CE (Embedded Compact). As a result they behave (and look) similarly. No different here. Panasonic (the maker of this OEM unit) uses Windows CE (either version 6.0 or 2013).
I had a top of the line Alpine Nav unit in my Subaru Outback. It had the same look and feel, and similar occasional quirky behavior.
