Hi De5i.

I had take a look at the site in your post on ebay. But is the unit wich I saw more people that have the same problems. I had tried to help another one, but I think something in software of unit is the problem.
Maybe you can ask the seller for an firmware update. I had problems with my unit to with the first Nextgen that I wanted to use. I installed new firmware on my S100 and all problems where gone.
