FAQ wrote:2. Can I use my mobile phone as a GPS?
No. Using the GPS function of a mobile phone, even if the phone is in a cradle, is not permitted. This is because a mobile phone can only be used to make and receive a call and all other functions of the phone (including GPS) are prohibited.
What a crock of shite! How is it any different to using a Navman/TomTom/etc?
Only valid reason for that specification is to remove an excuse for you when the porkers pull you up for "using your phone"
FAQ wrote:4. Where is the safest place to secure my GPS Device?
VicRoads recommends that drivers secure their GPS systems to the right of the steering wheel out of the central field of view. This ensures that the GPS does not obstruct the line of view of the driver.
Yeah because the A pillar doesn't already obstruct your view enough
