I searched for a similar post, but couldn't find one. If I'm just stunned & missed it, please point me in the right direction

i found Naviks, who sell a wifi adapter that plugs into the existing wiring harness for the OEM nav & will then allow me to mirror my iPhone onto the nav screen. Also allows me to connect the wireless backup camera. Sounds perfect for me, but experience has taught me that "too good to be true" usually isn't true.

Anyone have aver experience with this?
