New scala rider G4 won't turn on

[Goti]

I bought a scala rider G4 powerset a couple of weeks ago. Installed the latest software in both units and they were connected with a Blackberry (mine) and an Iphone (a friend). Everything was working fine and the only function that we didn't use was the Voice Dial.

Two days ago, both scala rider stopped working, no matter during how much time we press the Mobile button, they just don't turn on. Yep, both. Almost at the same time

They show a solid red light while charging but that's all they do.
It sounds stupid but .. both units stopped working after we use the Voice Dial function. it looks like a software failure but I just can't believe they won't work because of using one of its functions.

I already emailed Cardo so hopefully the'll take care of me. Meanwhile, I would like to know if any of you had a similar problem and how did you fix it.

Thanks!
