Roadnav is getting positional data from my Magellan eXplorist 210 via gpsd. Roadnav will then plot my position correctly on the moving map. However, Roadnav will proceed to decide I'm on a different road than I actually am and will recalculate the route to get be back onto the road it wants me on (which is the road I'm physically on). This cycle repeats every 10-30 seconds, rendering Roadnav useless for navigation.

Steps to repeat:
1) Connect GPS unit to computer and power on
2) Wait for GPS unit to calculate a fix
3) Launch Roadnav
4) Ask Roadnav to calculate a route from the current GPS position to a street addres
5) After Roadnav returns a route, start moving on the road Roadnav wanted me on
6) Drive along current leg of route
7) Roadnav will plot the GPS position icon directly on the road it has asked me to travel and update the position as I move
8) Roadnav will then randomly decide I'm on a road near the one I'm actually on
9) The GPS position is still drawn ON THE CORRECT ROAD
10) Roadnav will announce that it is recalculating and then read the new directions (which would return me to the road I'm already on)
11) This cycle repeats every 10-30 seconds

Configuration Data:
Roadnav v. 0.17
gpsdX v.1.5 (gpsd -V returns "gpsd 2.33 - EMUL enabled")
MacOS 10.4.9
Apple MacBook Pro 15" (Rev. 1.0)
Magellan eXplorist 210 (Firmware 3.2.53)

    I upped the priority because this keeps me from being able to use Roadnav. Sorry for the extra commit, I should have done this in the initial filing.

    I couldn't reproduce the problem here.

    Does this happen if you don't ask Roadnav to calculate a route?

    Also, if you could reproduce the problem with the debug log enabled, then send me the log, that would help diagnose the problem. You'll need to download one of the experimental builds from the download page, then activate debugging in the General tab of Preferences. Roadnav will then generate a file called roadnav-debug.log that will contain debugging info. If you could then reproduce the problem and send me the log, along with a brief description of what roads were displayed and what roads you expected to be display, that would help.

    I clicked on the downloads tab at the top of this page. I didn't see anything other than full release versions of Roadnav. Please provide me with a link to the experimental version you'd like me to use and I'll get the log for you.

    Today, I took a short drive with Routenav active to see if it would reproduce the problem in a location other than the one the bug was initially triggered by. In today's testing, the bug only occurred once. Because I was driving, I could not see where it had placed me, but it said "Recalculating" MANY times before telling me how to get back to the road I was actually on. I'm not sure if this is the same problem or not, but Roadnav was constantly telling me to "Go straight onto" or "Go slightly left|right onto" the road I was already on where there was nothing on either side of me but a river and some houses.

    The debug.log attached to this is from today's test. Sourceforge is not allowing me to upload the file. I have put it on my website at http://siriusphoto.com/forum_posts/roadnav-debug.log I will try to get someone to drive me the nearly 1 (each way) out to the place where I had the severe problem earlier this week. I should have that for you within the week.

    I am very angry at you for not warning me that testing the .18 alpha would result in the loss of all my maps. Destruction of user data is a cardinal sin in design. This was a unacceptable oversight on your part. Because of this, I wasted a significant amount of time and gas trying to get you data showing the problem only to discover that because you hadn't mentioned I needed to download new maps before I left home, I had driven almost 2 hours out of my way for nothing.
