Mac Haik Dodge Chrysler Jeep Ram

After I bought the car I wasn't told how to work some of the functions inside the vehicle also I can't open the vehicle from the inside meaning the trunk the vehicle will not let me make my own text message or send my own text message from the touch screen I just thought it would be a better vehicle and come with better features it be in a 2019 vehicle. Also can I get the whole 12 month trial on Cyrus because it was already uploaded on the vehicle when I bought it
