I have looked at the various threads on this issue and I have distilled to this (when oem rear view cam not installed by factory)
Go with rear view mirror solutions that split the screen like gentex or the one available on the costco site for about $170. link here
or
go with maxspeed integrated rear cam link here
All i need is a clear view of the back. I will rarely be parking in tight spots and dont really need the guide lines and beeping sensors and stuff. There is some nav-tv option but appears too pricey .. Please advise the best solution for my needs for a 981 S
