I have an OEM mirror for a Porsche 996 that has been etched ready to have the remote display installed in it. The mirror is brand new and ready to have the display disassembled and installed.
Includes the (etched) mirror glass and the housing.
$175 for the mirror as it is, if you want me to install a remote display first that can be arranged too. I might have a Cayenne mirror around here too somewhere.
Chris.
