I added the Compustar with the Drone app and it works great. The Compustar unit allows for fobs if you like them and Drone allows you to use your phone. I've found I don't actually use the aftermarket remotes, just the factor fob. If I need to remote start I use the Drone app. The Drone app is nice as it allows you to check status of the vehicle (for instance... you're sitting in a restaurant thinking... did I lock the vehicle? ) It was a little pricey and you do have to pay for the Drone service, however, with a 5 year plan on the Drone it got pretty cheap. Plus, considering the cost of any number of the Passport options, I just added it to the overall cost. Very glad I did it. Hope this helps.
