The voice will only work with the NAV. You will be able to put the piece right in no problem if you do not currently have the voice controls. It will take five minutes to install. 4 screws and everything pops out. The piece in the center of the lights shown in the link above) connects to a wire harness. Get it though, it is great! Learns any remote.
