> Especially when that GPS system is guaranteed to be worse than Google maps and not as well supported. I use my car's GPS nav over my phone's because I don't notice being appreciably worse for navigating, but I do notice the ads on Google Maps being appreciably worse than the lack of ads on my car's nav system. Also doing nav on my phone thrashes my phone battery.
