When using the ICA you will automatically get a built-in Satelitte Navigation System (SATNAV). Not only do you get a normal "SATNAV", but unlike any other on the market today, you get an on-screen visual aid as well.
The "VSATNAV" will paint a line on the road, all you have to do is follow the road, it will also give you an on-screen warning of any upcoming turnings and will highlight all road signs with the distance to your location on.
