The QNX CAR platform 2.0 RR uses HTML5, version 2.0.1.1 of Sencha Touch 2, and multiple versions of jQuery as the basis for the many components that make up the default HMI.
This HMI serves as a reference UI that provides programming samples to demonstrate how to integrate apps with the HMI. You can customize the default HMI or replace it altogether. For more information, see HMI Developer's Guide
