Mirror display?

I'm getting the Porsche TTS I've been dreaming of for the past 40 years.
Will pick up in early November in Roswell,GA and am having CarTunes Atlanta do the alp/Bel-sti-r install.

I'm considering getting the mirror display setup. Anyone have any experience/comments about the mirror display. I like that is not as obvious as a stand alone display unit.

Thanks,

Beautiful car! I think there are two types of mirror mods out there. One that etches the glass, and you can still see the etched area even when the lights behind it are not lit, and a second type where the lights are behind a two way type mirror that are completely invisible when the unit is turned off. I like the invisible type. The only thing about that location is followers seeing you have it if that is any concern.
