I'm just getting back in town and catching up on emails etc. From what I've read, the mirror doesn't appear to be Z specific but here is a picture of what it looks like. Also, here's more info on the mirror:
* Features a built-in monitor to help give you an improved view of what's directly behind you[*]
* Features a digital compass and HomeLink® Universal Transceiver, which opens garage doors and security gates
