I'm also interested in the Viper SmartStart and its compatibility with the 2019 as I was never impressed with Chrysler's OEM systems. Had them installed in our Town and Country van, 2012 Ram, and some of the loaners I've had. Seems like bad range for the units. Most of them I had to be real close to the vehicle where as my Viper system on my Expedition a few years ago would reach from forever away!
