Installation is simple - it comes with several mounts - I like the telescopic one with the suction cup. It connects simply to your phone either iPhone or Android.
Once connected you can use voice activation to make calls, control music through Spotify, and use Google maps for directions.
The hardest thing with it is hiding the wires - it needs power from a cigarette lighter, I also used an aux output from the radio to connect to the radio speakers but you could do this wirelessly using a radio frequency. Finally to use the revesing camera you need to wire from the back to the dash. All wires etc come with the pack.
Finally the screen size is excellant with very good resoluiton. Highly recommend.
