Navigon's hitting those holiday roads a day early, releasing version 2.1 of its iPhone app. The free update adds Google Street View, which pops up as you approach a destination, along with a Cockpit display, which includes G-force, speed and compass information for an additional $6. There's also a new Manual Route Blocking feature, enabling you to force the app to offer an alternate path after identifying a section of road that you'd prefer to skip, along with improved start-up and map rendering performance, and Retina iPad compatibility. The USA version of the app is available for $30 (a $20 discount), while the North America version is also 20 bucks off, at $40, and regional flavors will be available for $20 ($10 off). In-app purchases are also discounted, including FreshMaps USA for $15 (normally $40), FreshMaps North America for $10 (down from $20), FreshMaps MyRegion for $20 (instead of $50) and the aforementioned Cockpit for $4 (regularly $6). All of the discounts run through July 16th, so hit up the App Store and get your download on now.
