Car Play Installation Help
I just purchased and am in the process of installing CarPlay/AA from Thecarplayer.com, previously known as IndyWork. I do not have the wiring diagram nor have I been able to locate one online. I got it installed, but used others' videos and instructions. I somewhat guessed as to how it should be wired. The only question I have is how to connect their Aux-In/USB wirings. I have enclosed a picture of the way I have it, but am not 100% positive. I have written a couple of emails to the company, but so far to no avail. If anyone has any familiarity and can offer any suggestions, I would greatly appreciate it.
This is my question: Do I have Aux-In and the USB connected properly?
This is what my installation in process looks like. I hate to close everything not knowing if I have it wired correctly.
Thanks, in advance, for your help!
BTW: This is for my new to me 2014 S550 -W222

I have done two other vehicles (2018 Toyota RAV4, and my wife's 2016 GL350). The control boxes, however, for both including some wires in the harness were different. There is a nice installation video by GAT Car Kit, but this one I have looks different. The other challenge is that you can't test it without putting it all together, I think, as the controls are on the center armrest. Would you happen to have a diagram?
I think, if I connect the male usb into ubs inside the armrest, that would leave the female usb free to be used.
Thank you very much. I really appreciate your feedback!

Unfortunately I don't have one. This video should help. Do you have the rear seat entertainment system? I tested mine before completely re-assembling my center console, Just make sure the command system and command knob control panel is plugged back in.
I am really disappointed that I have not heard anything from the company, though.
Take care and have a great Thanksgiving!




In your photo I couldn’t see how it was wired into the Command unit. Assuming it’s correct do you have the dip switches on the CarPlay unit in the correct position?

My Command box is tacked in on the left side - I took some of the styrofoam out by the driver' side knee. That is why it is hard to see. I don't have room under the center console.
I am going to look at again just to make sure I don't miss anything.
Thanks, agan!!
