Firstly I hope I have posted this in the right place if not Im sorry.

Last year our satellite box in our caravan broke in my wisdom I proceeded to a German shop and bought a dual tuner Edision os Mini thinking id just plug it in and it would work, Wrong!
I dont know if I should just throw it in the bin or beg for help so here is the begging. I have the instruction booklet with uk 4 pages of NOTHING! I thought id have a look see if i could figure it out ound a update area so thought i would start there and updated everything it said needed updating now its stuck on a home page with OPEN AV and the box says Boot. is there any hope for me is there a walk through for idiots? I saw in a video there should be a usb stick in the box, there isn't. all i want to do is what tv when im abroad where in off to again in a couple of weeks hence why I have dug this out of its new box.
any help would ne great thanks
Bill
