I have SatNav built into my car, which I find very useful, particularly when I need to find my way to a place I've never been before. When trying to navigate en route, maps are not much help when you're in the middle of a busy ring road. Maps don't read out directions as to what lane to get into & can be more dangerous trying to read a map than texting while driving.

On many occasions I have also used my phone with Googlemaps on headphones on my motorbike, as that also gives audio directions.

Bear in mind, also, that there is now a new category in the UK Driving Test which includes being able to follow the directions of a SatNav.
