"grounding" means to connect the wires the car's chassis (metal). There is a BLACK wire on the back of the Z in the power harness that also goes to Ground. Just connect the 2 bypass wires to the same place as the black wire on the Avic. This will mean that you have 3 wires (2 for bypass and the black) from the Z connected to the same wire (or screw) in the car.

 

Yes, you will need to connnect your drive to a PC to upgrade to the latest 2010 maps/software, or you can order the upgrade DVD from Pioneer.

Thank you so much for the response...but by connect...do I do that with electrical tape? or do I HAVE to solder? or how do I do it?

Hey guys...please take it easy on me but I am trying tackle the "2wire" bypass on my z2 (upgraded to z3 w/ 2008 maps by previous owner) in my Nissan 350z with the help of these two links:

And this youtube video:

Everything seems pretty straight forward besides the ground the wires part. This is my first time toying with audio and electronics and I don't know what either of those two links mean by "grounding the 2 wires together"? I googled and searched but am still pretty confused with the the DETAILS on HOW to do it. Do the Z's have a grounding wire on the head unit or do I ground it to my car? In either case...HOW do I do either of those 2 options step by step? Thank you so much for any help guys.

SIDE QUESTION. Since the previous owner already upgraded my z2 to z3 with 2008 maps...would I have to still pull the HDD, plug it to my motherboard and do all the step by step again just to upgrade to 2010 maps?
