I have a 2017 CX-9 GT. It does not have the package that has the radar cruise control/lane assist part of it, as Canadian models made that an option.
Anyway, is there a way to get the traffic sign recognition to show up in the active driving display for 2016/17 models?
Hm, my car wasn't sold with different packages available. i-Activsense was automatically included on all trims except for the base trim (GS-L, GT and Signature).
Regarding TSR, I found this on a blog post published by a Mazda dealership in NJ:
"Traffic signs are detected and read using the car's Forward Sensing Camera. This information can also be pulled from the navigation system if it is stored there."
Do you have Navigation? If you do, and you can't enable TSR, then it probably needs to have the Forward Sensing Camera installed. If you don't have the camera, you might be out of luck.
For the 2016/17 models, there was a separate Tech Package available for the GT. It was all standard in the US GT. It might have changed in 2018. Read this: https://www.autotrader.ca/research/mazda/cx-9/2016/
I have navigation, so I was hoping it would pull the information from the navigation system. However, it does have Smart City Brake. Does SCB not use the Forward Sensing Camera?
