you  can  easily  get  the  VIN  (Vehicle  Identification  Number)  information  of  the 
currently identified vehicle. Once the VIN is successfully identified, the system 
will retrieve it from the remote server and then guide you to vehicle information 
page without performing the step-by-step manual menu selection.
