Heres the story i have a 99 GS 400 and I have navigation. the sound sucks. I want to put a after market radio in the car. Now the navigation is separate from the tape deck. I went a brought a harness from best buy. Now the two connectors fit with the connectors that came out of the tape unit, but there is a third connector and it works with the navigation. The climate and navigation wont work unless this item is plugged in. Please assist.
