Freewire-01 for Harley mic impedance/Carplay

    +1   Just discovering the issues with both Freewire and the Sena produced WHIM.  I am holding off on purchasing because of this issue.

    What would be the necessary modification of the current cables to enable Apple CarPlay while using the Sena Freewire.

    It won't be as easy as an impedance-matching transformer in the cable.  A transformer can match a Low z to Hi z, but there's not enough power in a highZ output to transform to low Z.   
    However, an impedance-matching amplifier in the mic output circuitry of a Freewire would certainly work.  Designs for such are commonplace.  If the Freewire had such a circuit, it would be truly and fully Harley Davidson-compatible.

    When I measure the ohms of my new 2023 cable from Harley, I'm getting 6k ohms. That is the only headset that works. None of the Sena cables work. I put a 1.5k resister in the passenger hed set plug in the mike terminals and car play will start with my freeware in the front headset outlet. I do get an echo in the mic and Sena has no support for there products.
