Okay, another issue you may not be able to help with:
I use MM while on foot (kinda useful and rather cool when you lose the trail under canopy), often in areas where satellite signal strength and fix varies. Now, I've noticed that when the MM/GPS system starts losing a fix, the imprecision skews along one axis. The resulting track shows the imprecision areas clearly as skewing along the same axis (I can get you a track if you like).
Does MM handle the GPS location calculations? Is this single-axis skewing along the direction of a particular satellite? Is there a way to judge the confidence of a fix, and "smooth out" the harshness?

Maemo Mapper 1.4 7 was great! 2.00/2.01 even better. Tried 2.00 yesterday
and 2.01 today. No problem installing 2.01 (after finding libXau0) on N800.
One question - perhaps I have missed something, but I have had to rotate the N800 by 180 degrees to use the Auto-Rotate mode so that the map display is consistent with my direction of travel. This did not happen with 2.00. Have I missed something?

As a generic test I entered a route from providence, ri to provincetown, ma. With this route I get the correct route track plus a near vertical line that pass just to the east of the start point in zoom level 2. If i pan south along this error line it soon is crossed by another horizontal line. It seems like different routes get different errors on varying zoom levels below 4.

Gnuite,
I have the same zigzag route lines appearing at zoom level 0. To reproduce the problem download a route from Liverpool to Chester, go to the first waypoint "Turn left at A59/Byrom Street" and zoom to 0. The zigzags appear over Hunter Street.

What is your platform? 770 or N800? OS2006 or OS2007?
If N800, did you install the RTComm stuff?
Did you "pair" the GPS receiver to your N800?
I've rebooted and still experienced the problem I describe with the Holux GPSlim 240.
I've got the N800 (firmware one before the current) OS2007 of course.
I do have the RTComm stuff. Hadn't seen it written earlier that this may cause a problem, so excuse me if this was already covered. I've been trying to keep up.
I guess I must have paired it at some point. It finds it and, as I said, it works for a short time. I drove with it and it worked while moving. However, I've had the GPS for months and don't remember having to pair it.

As for the NMEA capture, I'm going to need a hand on how to do that. What's the command I need to run to get that for you?

Thanks!

No, Maemo Mapper doesn't perform the actual fix calculation - that is the responsibility of the GPS receiver itself. Maemo Mapper has access to some satellite data, but not enough to make corrective judgement regarding the fix.

I'm not certain that RTComm is the culprit - I just remember other posts about people having problems with RFComm in combination with GPS receivers (and/or other bluetooth devices).

Actually, Maemo Mapper doesn't require bluetooth pairing, and in fact, I recall hearing about some problems with Maemo Mapper when used with paired GPS receivers.

OK, my experiences with 2.0.1:

I had multiple crashes.

I did not get warnings for direction changes (waypoints I think?) until after I was supposed to make the direction change. I am using flite but do not think this should affect the timing of the direction changes.

The gps location stopped updating, but I did not get any indication that the gps stopped updating. IE it did not say it lost connection with the GPS. I am using a holux slim240.

2.x was originally installed over 1.x . I did reboot at some point. I have gone back to 1.x because I needed something reliable.

I've had numerous problems with the application *poof* crashing, particularly while trying to download maps. In particular, I am trying to download several zoom levels of maps for the Seattle area simultaneously. MM estimates about 700 MB of data to be downloaded. It usually crashes within a few seconds after hitting ok. If I download a single zoom level at a time, I seem to be getting luckier.

Couldn't you use a symbolic link instead of copying the same file into multiple directories?

Thanks for the new version, btw. Works flawlessly on my 770.
