Just to clarify, the phone functions still do not work on this?

Also, I put a nav deck in my Supra and when I installed it I got the wrong wire for speed pulse and the nav was all over the place. It was choppy and would scroll crooked and not scroll straight when you were going straight down a road. Sometimes it would have me driving alongside the actual road for brief periods. Once I fixed the speed pulse wire it operated just fine. My concern with this mod is that I will enable the use of the functions but the nav will suffer. Have you guys noticed this with this mod?
