TA with nav and radio???

[Late Apex]

While getting an oil change today I closely looked at a new orange TA in the show room and wow it is much nicer than I thought. BUT as it is mostly a track designed car and Ralph's desire to trim weight, why does it have a nav and radio in the car? Fine for a GTS but in this model?? SRT design team even boast about a 2 Lb. weight savings with a CF cross brace but then add this equipment. Not seeing the logic for a TA? No salesman around at the time to ask but is the screen also for performance info and camera? If so, I can see why its there now.
