It’s quite easy. Probably can be done by voice but I have not got that far into the feature, only driven 600 miles so far.I just watched a review on the car. Is there really no way to change the radio station once the car is moving? That would be ridiculous if true.
Basic manual controls just forward of the very nice volume knob. It’s as solid as I have ever felt on even a high end sound system. But there are two knurled rolling swithches that work to change stations on radio as well as satellite.
I think there are some on the steering wheel too.
The touch pad is a bit more “touchy” to operate, but it can be done to change whatever, search, adjust sound position and basic equalizer. While moving!
