Can I add HD to my Z1. Will the GEX-P10HD or the GEX-P20HD work on this unit. Crutchfield says the 20 is not compatible, is it not. Is the 10 compatible?
IF nether of these will work what is the best plan of action to get HD without getting a new unit.
IF I upgrade the software can I use the Pioneer HD box.
I confirmed that a z3 will work with the hd box GEX-P20HD so I'm assuming that it's just software because the box hooks up through the cd changer port.
Also does anyone have drives for sale with updated software on them?
