I think you misunderstand my question. I'm ok with you calling it a POS...no problem at all. But if you feel that Pioneer is a POS, why swap it out for another Pioneer?
Personally, I've never had any issue with any Pioneer car audio products. I'd say the issue is with them trying to marry the car audio with a smartphone...especially one as locked down as the iPhone, it has enough problems on its own.
I answered your question above already: Because Crutchfield would only swap for the same brand.
I didn't call all of Pioneer's products a POS, just the appradio2. The 4400BH actually reviews quite well. However, we shall see how it works for real once I get my grubby hands on it.
