Read the section on new drivers - kids in their first year of driving. There is specific restriction on any form of wireless communication with numerous devices listed. With that as context it appears that the new law for mature drivers does not limit use of those devices, only cellphones. I have some quotes from school district interview with CHP I'll try topublish as soon as Finals are over.

Irregardless of the phone issue, there is an over-riding Vehicle code which makes it illegal to drive while being distracted for any other reason than prevailing traffic.
