i was not able to get my position, because the magellan sets my position in a street, only 20 yards in another direction! the module don�t accept my postion, even after calibrating with the software. today i read magellan updates the software to waas. i hope they don`t forget the companion ..... 30 yards is really worse in cities with streets sometimes every 20 yards ... i don�t want to guess where i am ...
A few thoughts:
How did you get your unit to "calibrate with the software"? I have one and generally accept that a $150 GPS unit may be a little off. I have seen "self calibrating" GPS, but only in an old Magellan GPS unit (can't remember the model) that was installed in a remote van for a radio station I worked for. On the occasion that I had to drive the van from North Dallas to the Ballpark In Arlington (TX) it was "off the street" for about 30 seconds until it figured out that I was supposed to be on the street right next to the icon. Then it snapped me back onto the street and the tracking was perfect from then on. That was of course a $3000 unit back then and probably had better software because of the larger hardware it ran on. (a big black box about the size of a 12-disc changer under the driver's seat)
I also attribute the error to the maps themselves, which Magellan may not have any control over. I have noticed that in the areas where the maps are off, they are consistantly off in the same places and the same distances. I think the GPS accuracy may be better than I originally thought but I'm a cheapo and don't want to purchase another mapping software package right now to compare the accuracy of the maps themselves. I'm using the software that came with the unit (MarcoSoft) until someone improves the software a little. Can we say, "self-calibration?" or perhaps Start to End Route Planning...something MarcoSoft says they're working on.
I guess because I'm using my GPS Companion for fun and not for pin-point accuracy is why the discrepancies don't bother me much, but if I had paid big bucks for a GPS mapper unit, I would expect it to make casual conversation (cabbie plug-in module) or drive the car for me (suicide add-on card).
