Absolutely none !!!!!!

It works fine, and it so cheap.

Yes, i know this setup is not software managed but i am not King Kernel Mark.
I'd like to install prel but still no success.

If you want try it, i think there is no risk .

I f you want try this setup on your stereo, or DVD amplifier and then if it works fine put it in your car.
I plan to use it also at home with my audio video stuff ......

But i want to find a cradle (paddle) for my phone, and I could test it on my Linux Box before Empeg .
