Frequently Asked QuestionsIs there support for non-US maps?There is no support for maps outside of the US. This is due to a lack of free online non-US data rather than a limitation with Roadnav's architecture. If you find a free online source of vector road map data for a non-US country that you'd like supported, please open a ticket on the Sourceforge tracker system with information about the source of data. Update: Support for OpenStreetMap has been added to the experimental builds. Feel free to play around with it, but keep in mind it's very alpha at this time so lots of things are still broken (e.g. city names). Patches to fix these issues are always welcome :) Update 2: Several folks have also pointed out Statistics Canada and Geobase put out Canadian maps in vector format. Their file formats are currently being evaluated. If you're a programmer and would like to help integrate them, please send me an email. What GPS units work with Roadnav?In principle, any GPS unit that puts out NMEA data should work, however, there have been reports of Roadnav not playing well with certain GPS units. A wiki page has been added to keep track of what GPS units work and what units don't work with Roadnav. If you haven't already, please post if your GPS unit works or not with Roadnav on that page. How do I change the map background color/road line width/make highways visible at a certain detail level/change the map appearance in some other way?The map appearance can be customized by going into Preferences, selecting the Themes tab, selecting a theme, then clicking the Edit button. The daytime and nighttime themes have to be modified separately. If you just want to make everything on the map bigger, you can also try changing the Zoom Maps setting on the General page of Preferences. Help! Roadnav told me to go the wrong way along a one way road/on ramp/exit!Well, don't do that then. This is a problem with the TIGER/Line data. It doesn't indicate which way one way roads go, so Roadnav has to assume they're all two ways, and as a result, sometimes you'll get invalid directions. If a data source with properly identified one way roads becomes available, it'll be integrated and this problem will go away. Where does Roadnav store its configuration information?Under Windows, configuration settings are either stored in the registry in HKCU\Software\Roadnav, or in C:\Documents and Settings\<your_user_name>\Roadnav.ini. On Linux, settings are stored in ~/.roadnav. Under OS X, they're in ~/Library/Preferences/roadnav Preferences. Where does Roadnav store its data files?Under Windows, data files are stored in C:\Documents and Settings\<your_user_name>\Application Data\Roadnavdata. On Linux, they're in ~/.roadnavdata. Under OS X, they're in ~/Library/Application Support/roadnavdata. Is a PDA/smartphone/embedded version of Roadnav available?No, currently, Roadnav does not support PDA/smartphone/embedded environments. Is Roadnav really free?Yes, Roadnav is free and will remain that way. However, this does not make Roadnav public domain. Roadnav is copyright and licensed under version 2 of the GNU General Public License (GPL). The GPL, amongst other things, imposes restrictions on distributing derivative works of Roadnav. Please read through the GPL carefully for all of the details. Are contributions accepted?Roadnav is strictly non-profit/non-commercial. As such, contributions are not accepted. Why do I get error messages when I try to download maps on my Intel based Mac?There is a problem with Roadnav's/wxWidget's zip file support under Intel based Macs. However, zip file support works fine on PPC Macs, so if you are encountering this problem, run Roadnav with Rosetta and then download the maps. Once you've downloaded the maps, switch back to running Roadnav in native mode. I don't see the big buttons on the left side of the Roadnav window.This means Roadnav can't find the skin files. If you compiled from source on Linux, make sure either /usr/share/roadnav or /usr/local/share/roadnav exists and contains the Default-Day and Default-Night directories. If you compiled from source on OS X, you'll need to change into the src directory of the roadnav source tree and do a "make roadnav.app" at the end. This will produce a roadnav.app package that you should run instead of roadnav and that will contain the skins. |
