Thanks for the feedback, I think I need to re-explain how the kit works on the website since it does confuse alot of people.
The kit provides both Apple car play and Android Auto. All you have to do is plug in the phone (either iphone or android) and away you go, I universally say "carplay" for both apple carplay and android auto, simple because its faster than typing both names out each time
I actually have just brought out a wireless version of the kit too, as soon as I get a spare minute, I will do a video demonstration of that.
The cars factory USB is not used for the carplay access, you must plug into the supplied USB dongle with your mobile. I mean, I could probably make the factory USB work with the carplay kit, but then this would disable the factory USB from the mylink (Since you cant have both connected at once).
So lets do a quick break down on how the kit works in two main parts: 1: Visual and 2:Audio
1) The kit displays the visuals/carplay by taking control of the factory screen. This is done by holding the top left of the screen, or double pressing mute on the steering wheel. When this occurs, if you listen carefully, you will actually hear a little 'click' as a relay engages to switch the screen display from the mylink box to the carplay box. You can then switch back to the factory mylink display by holding screen/double mute again.
2) The kit outs the audio by using the factory AUX input of the mylink. WHen I saw AUX, I mean the actual audio input which you can select by clicking the source button. All series1 VF's have the Aux option, but VF Series2 had this removed. The aux option can be enabled in the series2 with a bit of custom programming.
Basically, the VF series2 have the internal hardware to accept the aux input, but they disable it from factory.
Finally, to access the Aux wires from the factory unit, I put together a plug and play patch loom which connects between the mylink radio box and car loom to gain access to the cars communication line (gmlan) and also the three aux wires.
I personally have not used the VF Kayhan units yet. But based on their previous products for VE's, they have been fantastic, along with providing updates for any new features or bug fixes.
The VE Android units I supply are Kayhan, they are one of the only products I supply that are not put together by myself since I am a fan of their work and products.
