I just got my pioneer Z130bt, when I went to pair my iPhone, the settings in which you do that is greyed out, and so is the nav settings and everything else except for the audio settings. PLEASE ADVISE, I didn't hook up the parking brake wire or bypassed it yet, could that be why??????

Yes. You can't do much without either the PB correctly connected, or the bypass. Until you do one of those, what you've got there is an expensive radio/ipod/cd player that will show you where you are.

Yep you are correct I bypassed it and everything works great

Thanx
