GPS - Bike Computer uses turn-by-turn navigation to make it easy to see where your next turn will be. This is the same system Google Maps uses, and just focuses on one turn at a time so it's easy to glance at your iPhone and see when you need to turn next.
If you want to download maps before your ride to save on expensive mobile data, you will have to pay a monthly fee of $5.99/month or $49.99 for the whole year. Similarly, a voice won't call out where the next turn is without subscribing to this subscription plan.
