I have spent the last ten days dealing with Mio on the phone. Call the number, and its a VOIP line to the Phillipines. Staff are less than helpful, wont return calls and wont provide details of Reps in Oz.
Due to their upgrade I now have a Navman OS in a Mio body that is to all effects a $350.00 paperweight.
Now I own a Tomtom 730. Had a small issue, rang the technical support number, 2 minutes on hold and a lovely lady called Anna sorted out all my problems with an invitation to call back if I needed to. I couldn't be happier with Tom-tom service.
