I asked the seller about the manufacturer and so far have not had a reply. As you mention, the price (and apparent features) make this unit attractive.. Is it worth the risk?....at this price point....don't know. I am not knowledgeable enough on DVD/GPS head units to make an educated decision on the risk. I don't know what I don't know. Perhaps folks who have interest and have the knowledge can ask questions and hopefully get the answers from the seller. I sent the seller this link so perhaps he can monitor and respond.
