***UPDATE 191009 2pm***
Seems like its a win for common sense

- Changes to the new mobile phone rules
The new mobile phone rules have been revised. The change now allows both the navigational (GPS) and audio/music functions of a mobile phone to be used, provided the mobile phone is secured in a commercially designed holder fixed to the vehicle.

——————————————————————–
Just like most roads ministers, it’s amazing that they all talk large with little vocal opposition, but when they need to do a backflip they run a mile from being public.
Today we have discovered that the 10years revision on the Vic Road Rules (already 12months out of date) have had some significant changes slipped in.
Changes have been made to the wording and direction concerning the use of GPS on a mobile/smart phone.
Mobile phones
Using a mobile phone while driving to make or receive a phone call or listen to audio/music is prohibited except if the phone:
is secured in a commercially designed holder fixed to the vehicle,
or
can be operated by the driver without touching any part of the phone.
Using a mobile phone as a GPS while driving is prohibited except if it is secured in a commercially designed holder fixed to the vehicle.
All other functions (including video calls, texting and emailing) are prohibited.

But Vicroads reading of the fine print is a mess.
