Megavision karaoke questions

[v2s13]

---

We just bought a megavision karaoke machine. The problem is someone threw the box with the manual in it. How do you update the firmware? Where can I update the karaoke songs? How can I delete the movies that are pre uploaded in it? Paxenxa sa daghan questions And lastly I already googled about the megavision, couldnt find their website either. If some pls post a link on their website. tnx
