sorry to bring up an old thread but finally got some support/looked back into trying to do this, looks like i will need to get a new face unit
Thank you for writing to us at Kenwood USA Corporation.
Unfortunately, the Z919 was not designed to accept the CA-C1AUX (13 pin to
RCA) auxiliary adaptor.
It is not possible to add an auxiliary input to the Z919.
If you have any further questions or need help with anything, please feel
free to contact us again.
