Mine allows data entry while moving with no passenger. 2014 v8s

 

I had never tried it on my F-Type, but my Jeep doesn't allow it above 30 mph, and neither does my wife's C-300. I recall several of my other cars not allowing it either.

However, I took my F-Type in today to have the bumper bar license plate bracket holes repaired, and they gave me a '15 Range Rover Sport as a loaner. I tried it in the RR today while at 65 on the freeway, and it allowed me to enter address data.

Thus, there is clearly no regulation prohibiting it in the U.S., but it seems that the legal departments of many other manufacturers have decided it would be prudent to lock it out at higher speeds.

Given that the OP is in Australia, perhaps it's officially frowned-upon by the government. I'm sure it's easy to allow or lock out with just a software reflash.
