outcome is full integration of everything. Watch movies on factory nav, g510 with traffic on factory nav, sound output with mute through new Head Unit. Head Unit has ipod, dvd, usb, sirius.
Looks like you used the Kenwood DDX814. This is what I want to do. Just trying to figure out if I should use the factory nav or the g510. Not fully understanding your connections from g510 to oem screen and HU.
What is the "extra cable from head unit"
