tracking

So as the title says we are just wondering how MyMazda.com get updated mileage information. Is the vehicle using our cell data over the BT connection or does the CX-5 have its own cellular or wifi modem?

Hi I'm looking at some wheels and wonder if unilug wheels bolt to a Mazda without spacers/adapters, etc. I'll be doing some tracking so I'm not going to go unilug if these wheels don't bolt up cleanly. Also with all those drill holes are unilug wheels too weak for tracking? BTW, I did search...
