DMP car design. Screen. Worst product 

I have purchased the screen about a year ago in the summer time from DMP car design so far I’m having so many issues the worst product for this vehicle. I have tried to contact them they have deleted and blocked me from all the contacts that they provide for them to contact.
DMP car design is the worst customer service and technical support team. In this video I tell you all the issues that I’m having that nobody seems to talk about.
