Head unit not loading UVO, the SAT-Radio plays but no station info is shown

What is your question?

My 2015 KIA Cadenza Premium head unit screen flashes light to dark, sometimes the UVO logo will just display but never completely load, I can get xm-satellite stations but no screen information. I have tried reboot (soft and hard), I even bought a used unit (that's the one that just flashes, the original unit just has the UVO logo on screen trying to load the software) both will play the radio and satellite.

How long has your 2015 Kia Cadenza had this problem?
