Does it work like factory? How would you upgrade the maps when the time comes?

yes it works just like factory as far as the map upgrade I don't mind paying $150 to upgrade it if I need to but so far as much as I use it and I do use it often it gets me to my locations and so far all the roads I have had to travel have been on there I may not upgrade it for a few years maybe more so long as the roads that I travel are still current once I start seeing a difference in streets that have been added or closed than I will upgrade it

this kit only will expand and give you navigation options if you already have an 8" screen in your truck the link that I put down gives the new 8" screen and radio bezel to replace your 4.2" screen if you have that like I did and they also give you the HMI unit and a GPS Antenna.
