I think the one you listed is for aftermarket head units. I bought this instead and it looks quite promising, take a look if you'd like.

I see! I followed your guide and successfully swapped my radio. Any chance you look into bringing more functionality to the head unit like the phone answer/reject buttons and even HDMI? Thanks anyway the touchscreen radio makes my car much better than the stock one that came on the LX
I have a LX too and swapped with a EX radio. Out of the 4 factory harness that plugs into the radio, only 3 plugs into the new radio. Is that the same for you? What is the last harness used for?
