About the z2 bypass update iso, if im making a z2 image on a new HD, since i have a z1 already with the 2 wire bypass. Do i still need to update my z2 with this iso update to make the dvd in motion and so on? Or is the 2 wire bypass work?

I am pretty sure it includes the 2 wire bypass

It does

what do you mean includes 2 wire bypass? you have to do it yourself, you mean the software on the z2 bypass is already in there? You need both bypasses to work the z2

yes you have to connect the wires the software is there

oh ok, i already have 2 wire bypass
