I emailed the company (MXData.co.uk) with this enquiry:
How would I be able to use this service on my mobile, if I'm not allowed to use a mobile whilst driving?The next day (23 Dec 2007) I received this response:
Just start the application before you drive off, set it to auto refresh the data and place it in a holder on the dash....then you only have to glance at it, you can set it to night colours just like a Tom Tom etc.This is all well and good, but what happens when the phone rings? Are you really going to just ignore it while it's sat there in full view? Of course you're not, so the application seems destined to rack up points on the poor driver's licence.Alternatively a passenger can use it for you.
