Go to Factoryradioparts.com, for $389.00 you can add it in a couple mins.I love mine and gave my son my top line Garmin that I just got for my new RAM.I think the site might be under construction right now, it tells you how to get the code from your radio, email it to them, pay with paypal. A while later they email you activation code, you type it in your system, and 2 mins later the nav pops on. I did have to go into my apps find the icon and drag it down. I hear lots of people don't like it, but I would buy it again in a min.I really like it!
