Hi, I just received the same bluetooth adaptor and plugged it in the CD changer port. I can get the bluetooth to connect to my iPhone but the head unit displays "external unit not connected" when I select the CD option on my head unit. I did not get the Y adaptor to keep the CD changer plugged in as well. Do you think that could be the issue? I'm glad to order one but just trying to make sure that is the problem first if you happen to know.I have the nav option. I have a LX not LC but I think the units are the same. I will add that since the install my unit has started to intermittently glitch/freeze. I don't see how this install could be at fault but the added functionality is worth putting up with the infrequent glitch. I thought it was a cracked pin 60, documented elsewhere, but I resoldered that pin with no luck.
