Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

If you are able to reset it to get it to turn on and operate but there is an issue with the display itself the first thing that needs to be done here is to have the power and grounds checked to make sure these are connected properly at the back of the radio itself and that the correct power and ground signals are working at the back of the radio.Most likely they will be since it does reset and work properly ( except for the display).What causes this fault here that I have seen in several cases before is a fault with the radio itself internally.The circuit board acts up causing no display like you see here.If power and ground is present at the back of the radio then the radio itself needs replaced or removed and repaired by an authorized repair center.You might check with the facility you had purchased it from since it is just a little over a year old to see if there is any warranty on it.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
