Re: Navit GPS (and libgarmin) for os2008

Can you post your navit.xml so we can check it out?

I found that in order for my maps to show up properly I had to set my initial center point to a point within the area of the maps, otherwise Navit opened up at some unmapped point. Did you set your center point in your navit.xml? I used Google Maps to find my house and then pulled the coordinates out of the "Send Link" URL.

Re: Navit GPS (and libgarmin) for os2008

Thank you very much for offering help. With few changes, I finally could able to load the maps. Now, the destination form is not working. I entered a place in the Route->Destination form. There were no OK/Cancel buttons to hit. Did you try this facility?
Thank you once again.

Re: Navit GPS (and libgarmin) for os2008

I'm at the same spot. I can enter a location into the Destination window but there's no OK/Cancel, nor do any of the other buttons seem to do anything. I have no idea how to get it to work!

Re: Navit GPS (and libgarmin) for os2008

We have 4 navigation applications available for Nokia Internet Tablets, but at the same time none of them are complete in nature.

MaemoMapper is a mature and stable application - But Map files are too big to download and importantly, it needs internet connection during travel to do routing/rerouting.

Wayfinder - Involves $130/- for 3 year period. One time investment is OK, but I don't like recurring exp.

RoadMap is a good one, it uses vector maps but so far Routing/Rerouting engine is not available yet.

Finally Navit, similar to RoadMap, it uses Openstreet maps, not fully functional. But as per the developer Navit can do routing/rerouting but so far it is not working. It would be great if he looks into the issue and makes routing/rerouting works.

Re: Navit GPS (and libgarmin) for os2008

Hi everybody, sorry for the late response.

Please take in consideration that Navit is in alpha stage and the N8x0 port is more alpha than the PC version. Actually there's a memory/cpu limitation in how Navit handle big maps, specially garmin ones. Please try to keep your maps as small as possible and use Swap.
The project is really promising, a 3d gui using SDL could be possible to do (I'm working on that) and routing is 90% finished. It's just a matter of time, so patience :)

Thanks.

Re: Navit GPS (and libgarmin) for os2008

And thank you for it! 90% sounds great.

Thanks for the update and goodluck with the progress. When you say 'keep maps as small as possible', how small. I am using Navit with 70% US maps, i.e., little over 600mb. How small should I reduce them to. Can I have atlest my city (Columbus) which will be around 30mb?

Can you explain the limit please. Navit seems to work great with full Euro maps (1.4GB) from Reisenplanner. Are roads/labels missing or something?

Re: Navit GPS (and libgarmin) for os2008

Hi, i don't have a limit table, if you are having problems with seg faults, try using smaller areas and please post the results here. I find argentinian garmin maps too big for the device and sometimes it crashes Navit.

Thanks.

Re: Navit GPS (and libgarmin) for os2008

back in the day, i built a quick and dirty maemo pacakge for v0.0.3. it used
a shell script to build the xml config at launch time with the available maps
- maybe this will be useful to you. see below:

Code:

#!/bin/sh



XMLCFG=/tmp/navit.xml

NAVITROOT=/usr/share/navit

MAPPATH="${NAVITROOT} /media/mmc1/Maps /media/mmc2/Maps"

MAPCOUNT=0



cat ${NAVITROOT}/preamble.xml > ${XMLCFG}

cat ${NAVITROOT}/layout*.xml >> ${XMLCFG}



if which flite >/dev/null; then

  cat ${NAVITROOT}/speech_flite.xml >> ${XMLCFG}

fi



for p in ${MAPPATH}; do

 if [ -e $p ]; then

  if [ `find $p -name *.bin | wc -l` -gt 0 ]; then

    echo '<mapset enabled="yes">'

    for m in `find $p -name *.bin`; do

      echo '<map type="binfile" enabled="yes" data="'$m'"/>'

      MAPCOUNT=$[${MAPCOUNT}+1]

    done

    echo '</mapset>'

  fi

  if [ `find $p -type d -name *.map | wc -l` -gt 0 ]; then

    for m in `find $p -type d -name *.map`; do

      echo '<mapset enabled="yes">'

      echo '<map type="mg" enabled="yes" data="'$m'"/>'

      for mm in `find $m -type d -name *.smp`; do

      MAPCOUNT=$[${MAPCOUNT}+1]

    done

    echo '</mapset>'

  fi

  if [ `find $p -type d -name *.map | wc -l` -gt 0 ]; then

    for m in `find $p -type d -name *.map`; do

      echo '<mapset enabled="yes">'

      echo '<map type="mg" enabled="yes" data="'$m'"/>'

      for mm in `find $m -type d -name *.smp`; do

        echo '<map type="mg" enabled="yes" data="'$mm'"/>'

      done

      echo '</mapset>'

      MAPCOUNT=$[${MAPCOUNT}+1]

    done

  fi

  if [ `find $p -name *.img | wc -l` -gt 0 ]; then

    echo '<mapset enabled="yes">'

    for m in `find $p -name *.img`; do

      echo '<map type="garmin" enabled="yes" data="'$m'" debug="4"/>'

      MAPCOUNT=$[${MAPCOUNT}+1]

    done

    echo '</mapset>'

  fi

 fi

done >> ${XMLCFG}

 

cat ${NAVITROOT}/postamble.xml >> ${XMLCFG}



exec ${NAVITROOT}/navit ${XMLCFG}
