[futiless]

Hi I am trying to convert my GX 2015 Mazda 3 to support Navi. I bought the CMU, and the Actual display. What else do I need to convert as I gather there. Does anyone know if I can get a TAU w/o bose (keep current speakers) and still connect to the new one on the top. My connectors at my dash are at the bottom.

I know I need command dial and cable, USB ports and aux. Video camera backup ?. steering wheel what else is there can I complete this or is this a futile endeavor.

Please and thanks
