I have a 2019 PPV without remote start but I have key fobs with remote start capability. The RPO list does not have RPO BTV, unfortunately. Is there a way to add the BTV capability using stock stuff? I do not want aftermarket systems. I have see that the next generation Tahoe has a way that upfitters can get GM to change the option list with GM and then make a software change, but I have not seen anything similar for a 2019. Is there a physical part that can be installed to add the capability to a 2019?
