the rotary dial is the touch pad. you can draw on it but it won't necessarily move the cursor so to speak like a PC. For example next time yo need to look up a phone number, instead of using the dial to choose letters try drawing them. Of course do all of this in a safe manner
I find that it is about 60/40 figuring out what I want, if I get frustrated I go voice for more fun and games.
I still need to figure stuff out with the car. and as always it is a blast to drive
