I just got my AVIC-Z2 yesterday so it's a post june unit. When I load the ISO crack cd I get this message.....

"Old version update disc insterted. Please insert new version to update."

So unless I'm not reading things right on here, I should just have to do a 2 wire bypass..... correct?

I believe so.

correct

got wire #1 done. pulled my unit out to ground the wire #2 and best buy didn't plug in connector 2. it's in the box back at home! we'll see after round two. it's nice not having to set the parking brake though.

wire #2 grounded! it works! thanks people.
