Air temperature display on i70 or es98 MFD

Hi,
I've been trying to display the air temperature on our i70 display or eS98 MFD. Do I need another device to provide that information to the system, or is it integrated into the i70 or es98 MFD?

My personal GPS has that feature built in, so I am hoping it's already available within the current system.

If another device is needed, what is it and where is it available?

Thanks,

C
