And again i have bad experience with this aliexpress shop. I bought CarPlay mercedes unit with separate D2B box. Both this item's not working properly. Spend 3 days to fit. Nothing work. Only crash my car system. I opened return. They accepted return for CarPlay unit but not for D2B box. And they ask me pay return cost first. They said that after they will give me this money back. But this shop it laying on every time. I have returned my previous order,i paid first. But then i contacted whit them many time and ask money back for return shipping cost. They ignored. 3 months gone but i didn't get my money back. And now they ask me pay again for return. Total scammers. I move out from this shop and can recommend avoiding do purchases to others.
