Is it worth getting a sat nav? Watch
I really don't think a couple of minutes (assuming you even let your battery drain that far) is enough of a reason to require a separate device to do an identical job.
It's unnecessary to have a standalone device for this.
I won't get into how poor the satnav market is in terms of planned obsolescence.
True but a sat nav is more focused on being a map but a phone is more for other stuff. Google maps isnt that reliable
Google Map is a hell of a lot more reliable and up to date than a satnav.......
