I believe that for the Z1 you will need the 7" bezel which is different than mine, Also it takes longer to make. But it's all worth it if it look clean. everyone who has seen my unit latley has been WOWed. talk to rich @ mybimmer.net. His work is qaulity. Also it's just a face cover tha matches up with the cage for the OEM radio. you will need to modify the OEM cage to work with your unit. Some of the links I posted show different ways of going about it.
