DEI 530t 2011 dodge charger
 

I took my vehicle in today to get the window module installed at a professional stereo shop. The installer took 2 hours to try and install it and ends up telling me he can't do it because of the data port involved with the factory window module for my vehicle. Is it possible to install one of these for a newer model vehicle? Can anyone explain this or have ever had any issues with installing this. I really want this feature for my car. I already have a viper 5706v installed. Thank you
