Has anyone actually answered the question you asked. I am currently researching the same thing and before I make that purchase I was looking to see if there were any inputs on the functionality of it versus any issues that they have caused. There are option I can see but I am more worried about how will it affect the other workings of the truck. I am looking for this install because I respond to emergencies with my truck with local agencies and would like to be able to leave it running while taking the fob in my pocket to keep it locked, I am also looking to have the remote start function with it. I see the reason to install a single unit that covers both the desires I have.
