I recently bought xk convertible 2007.
It's very cool, but only the antenna feels old.
I want to keep the antenna retracted when using a CD or aux.
I want the antenna to come out only when the source is selected as radio. Does anyone know how to run it just by changing the settings in the car computer software?

 

You can pull fuse F4 in the Auxiliary Junction box to entirely disable the antenna so you solution would be to add an on/off toggle switch to manually control the antenna. No software options.

 

Thank you for your answer.
I understand that it cannot be controlled by software.

 

I removed F4 within a month of getting my '07 in 2015. I listen to my own CDs and have never looked back.

 

I had had two XKR MY 2008 (Europe) in the past. When I bought my current one (first registered in 2008; built in 2006), I was kind of astonished about the antenna. But the previous owner had built in a manual switch (in the glove box) enabling to disable it when not needed. Far from ideal and very old-fashioned for a reasonably modern car, but at least it elimantes this awful tsunami…
