Sinotrack ST-901 mileage

I have a Sinotrack ST-901, ID 9171801XXX.

When I connect the unit to my car and my server I receive data like:

*HQ,9171801XXX,V1,004932,A,3329.2332,S,07034.4444,W,0.00,55,020321,ffffffff,000,00,0000,0000#

The information is perfect, but I don't see the mileage, can you help me to configure my unit to get mileage as a part of the received information?

It looks like the SMS information after you sent rconfig? In my ST-903 is no mileage in this information but I can see it in the portal in the status informations.
Here a link for setup the ST-901: http://notadmin.com/gps-tracker-sinotrack-st-901/

Mileage is calculated by server as long tracker reports position changes..
