Location of AM / FM radio chassis in T86 with Touch display

[SkidTracks]

Where is AM / FM radio chassis located in a T86 with Touch display?

Radio controls are down below Touch display, but radio chassis is not there.

Bobcat's online part manual does not show AM / FM radio chassis for T86's with Touch display.
Manual only shows standard AM / FM radio with display and controls.

Bobcat dealer says AM / FM radio chassis is located behind a panel by right knee.
