It is a bluetooth device so you can use it to make calls this works without ever having to touch your phone call lists and contacts come up on the screen and calls can be made direct from the head unit

It has sat nav in two forms you can either use google maps and have the device hot spotted to your phone or you can use an app with pre downloaded maps so no connection is needed

I received it not knowing what to expect i was hoping that it would live up to the description and other reviews and i have not been disappointed it really is an all in one solution for your car
