You might not expect Bosch to be in the sat-nav app market, but the iPhone-oriented Navigation offers a pretty reasonable option. Most of the core features you would expect from a sat-nav are available, including address search by street keyword, and a traditional points of interest database. Traffic updates from INRIX can be subscribed to as an optional extra, and there's a warning system when you approach sharp bends. You can also send updates about your journey to Facebook, Twitter and Flinc. However, no traffic camera locations are provided. So whilst the sub-£45 price is decent, this isn't quite the perfect iPhone navigation app.
