I had a problem with the first Pioneer Elite i installed... The cable that came with it was bad, and replacing it solved the problem (we needed a longer cable, anyway).
The bad cable i had could have possibly caused problems down the road...
The other Pioneers (and Sharp- same units, different operating system) haven't had any problems at all
We can do it my way, or we can do it my way while I yell. The choice is yours.
