Hi. Was shopping on the Mopar site and found this upgrade. Info is very vague, and the installation instructions pdf would not load in I.E. 11 or Chrome. Can you tell me what the upgrade would bring to my system? I have a 2013 Durango R/T with an RHB radio. Does it do things like enable text to screen? Thanks for helping.
