I tried this but got a hash sum mismatch error on install. Any ideas?
Navit is an open source turn by turn directions app using the free Open Street Maps.
It is important to note that both the app and the routing engine, along with the map data are all Open Source!
The app is in beta still and can be downloaded using Cydia.
Add this source http://szndvc.dyndns.org/cydia/
and then search for "navit"
You need a planet.bin file of the Open street maps data. You can use this http://maps.navit-project.org/planet.bin but they have a tool that lets you select a portion of the map to download.
That file will go on your iPhone at var/mobile/Media/Maps/planet.bin
at what point during the install did you get that error?
After completing the download, prior to beginning the install. Some googling indicates that it could just be that the server is very busy.
I tried ICY but after adding the repository couldn't find the navit program.
[Edit] Managed to download it! Working now.
I just gave this app a try.... wow, it is definitely not user friendly! Give xGps a try... seems much better than this one. It does turn by turn with voice prompts as well.
This whole 'pay for mapping' thing has got to get worked out. I understand that the mapping companies add value by improving the data and making it routable and so forth, but the technology and the user base is out there now to allow a free, open, and likely better solution to this problem.
At any rate, a viable open source map and data will force a reduction in price for maps by the likes of Telenav.
OpenStreetMap data is good enough to do routing right now. In other areas it needs improvement, but we have tools to do the improving. You can look at the map at http://openstreetmap.org and there's tons of information about the project at http://wiki.openstreetmap.org.
We're going to have a combined mp3Car / OpenStreetMap gathering in Baltimore in late August. Date still TBD.
Cydia's source is now hosted on navit : http://download.navit-project.org/navit/iphone/cydia/ with better bandwidth and server.
About user's friendlyness, feel free to report your suggestions : http://trac.navit-project.org/
Navit is meant to be fully customizable, hence it's probably a bit less easy to learn.
XGPS has two drawbacks according to me :
- it needs data connection. Sometimes you are in a poorly covered area, or abroad and your data plan might not be available and you might not be able to compute a route
- maps aren't rotated, which isn't convenient.
