Apple finally allows turn-by-turn directions on their Iphone 3G Device. 

'''Navit can now be ported to Iphone 3.0 firmware.'''

You can now have a '''free''' GPS car navigation system for Iphone.

== Status ==

===Version: '''Beta 0.1'''===
*0.1-r2391-2 (adding landscape, cursor, navigation status...): 29/07/09
*0.1-r2391 + (garmin driver): 08/07/09 
*0.1-r2391: 05/07/09
*0.1-r2307: 27/06/09

===What works===
* Routing
* GPS updates
* OSM maps
* Speech (OS<3.0)
* Track logs
* Landscape/Portrait mode (SDL patch)

===What does not===
* speech (play failure since 3.0)

===What was not tested===
* Garmin maps (Last binary includes Garmin driver but not tested ...)
* Others maps

===What is on development===
* Update current tracking algorithm to prevent from road jumping
* Speech for 3.x

==Concerning Opentoolchain==

===Cydia packages===
'''Temporarily''', Packages are available through this below repository:
 ''main-dev (latest)'': http://szndvc.dyndns.org/cydia/
 ''main (r2307)'': http://download.navit-project.org/navit/iphone/cydia/
 

From Cydia go to Manage > Sources > Edit > Add and add one of the above URL there. 
Then Search->"navit", install it .

By default, navit is expecting OSM maps:
 /var/mobile/Media/Maps/eu.bin
 or
 /var/mobile/Media/Maps/planet.bin

For example, you can either use:
* iphone terminal and wget:
 iphone$ cd /var/mobile/Media
 iphone$ mkdir Maps
 iphone$ cd Maps
 iphone$ wget http://maps.navit-project.org/planet.bin

Or
* openssh
 PC$ wget http://maps.navit-project.org/planet.bin
 PC$ scp planet.bin root@xxx.xxx.xxx.xxx:/var/mobile/Media/Maps/planet.bin
xxx.xxx.xxx.xxx is the ip of your iphone.

enjoy having your free GPS on your iPhone. 

PS: Temporarily, because I hope it will accepted on telesphoreo.

===Home made packages===
I assume that your cross-compiler is ready and that you are able to generate telesphoreo packages.

* Cross-compiler: [http://code.google.com/p/iphonedevonlinux/wiki/Installation]
* Telesphoreo: [http://www.telesphoreo.org/]

 svn co http://svn.telesphoreo.org/trunk  
 export PATH=$PATH:$WHEREIS_YOUR_TOOLCHAIN/toolchain/pre/bin
 export PKG_BASE=~/WHEREIS_TELESPHOREO/trunk
 export PKG_ARCH=iphoneos-arm
 export PKG_CONFIG_LIBDIR=~/

====Libraries====

First you will need to compile below libraries:

*FreeType
*FontConfig
*SDL
*SDL_image
*Png
*ImageMagick
*Jpeg6b (optional)
*Tiff (optional)

Png, tiff, Imagemagick are already available on telesphoreo which is the APT-based distribution of Unix software for modern smartphones started by Jay Freeman (saurik). So you can download it from Cydia.
For others, you will find all necessary telesphoreo patches on below ticket:
[http://www.telesphoreo.org/ticket/159] 

  patch -p0 < sdl_ft_fc_jpg_new_packages_telesphoreo.diff

Currently, I hope that above libs will be accepted on telesphoreo distribution to skip this first step.

Then we can deal with Navit code.

====Navit====

Please find below telesphoreo patch for navit: 
 r2391-2:http://szndvc.dyndns.org/navit/telesphoreo_r2391_2.diff (full patch + deps)
 r2391+garmin:http://szndvc.dyndns.org/navit/telesphoreo_r2391_garmin.diff (full patch + deps)

 r2307:http://www.telesphoreo.org/ticket/167

'''This is a draft !!'''

I know, there are some obvious workarounds and hacks! and my OBJC is rusty :)

Includes:
* [Iphone] New vehicle type: Iphone GPS coordinate reading
* [SDL] options in config file for BPP and NOFRAME (2391)
* [OSM] search in unknown city (without is_in tag)
* [OSD] Announcer toggle fix
* [DBG] Added HAVE_NO_DEBUG (Iphone does not like hash calculation :))
* [NAV] Added tell_street_name in configuration file (2391)
* [CONFIG] Navit XML configuration file for Iphone 
* [FILE] !!Dirty!! Hacking file_wordexp_new(). Indeed wordexp seems to not work on my env :(. All "*" for file path are not allowed yet. Direct path only.
* [BUILD] !!Dirty!! with disable-plugins mode, darwin gcc seems to not link plugins from *.la => Force link against .o and add all libs to navit_LDADD 
* [EXTRA] Iphone application metadata (icons ...)


Once your telesphoreo source code is patched with additional libs and Navit. Just enter below command 
 ./package.sh navit 
It will build navit and all other dependencies (above libs).

Upload your deb files (scp,ssh,...) to your device and install them thanks to dpkg ...

 dpkg -i fontconfig_2.6.0-1_iphoneos-arm.deb
 dpkg -i freetype_2.3.9-5_iphoneos-arm.deb
 dpkg -i sdl-image_1.2.0-r4521-4_iphoneos-arm.deb
 dpkg -i sdl_1.3.0-r4521-1_iphoneos-arm.deb
 dpkg -i jpeg_6b-14-x_iphoneos-arm.deb
 dpkg -i navit_0.1.0-r2307-x_iphoneos-arm.deb

'''Then Have fun :)'''

==Concerning App Store==

Need a volunteer with a mac :) 
*SDL is ready for Xcode
*...

==Config==
OSM map files are expected as below: 
 /var/mobile/Media/Maps/eu.bin
 /var/mobile/Media/Maps/planet.bin

A new navit.xml can be copied into ''/var/mobile/.navit/''
===Video===
 <graphics type="sdl" w="340" h="480" bpp="16" frame="0"/>

Frame and bpp options have been added

===Speech===
Get '''festival''' library + '''Erica utilities''' on Cydia.
Then change your speech configuration in "/var/mobile/.navit/navit.xml" to

  <speech type="cmdline" data="flite -t '%s' -o /var/mobile/tmp.wav &amp;amp;&amp;amp; play /var/mobile/tmp.wav &amp;amp;"/>

==Test feedback==
* OSM: Routing is very slow (long distance is a nightmare for user :() (Almost fixed with CACHE_SIZE define)
