My favorite site for working with GPS and mapping files is
http://www.gpsvisualizer.com/gpsbabel/convert
It is a user friendly interface for converting multiple file types using GPSBabel. I recommend anyone interested in using or sharing files to become familiar with GPSBabel. It is a powerful tool.
First of all, thanks for sharing this link. I just converted a National Geographic Topo track into a .gpx file! I have a bunch of stuff I saved on NG Topo from before I realized I would be better off having it in a format that I could put into my GPS. You have made my life much better just by posting that gem of a website.

I love what you have done there! My whole point of prodding information out of you guys is to make something similar on

. I want to know if the average user will be able to make real world use of track files posted here. I have a bunch of Moab trails saved in .gpx, I can also make .pdf maps that
should print out nicely on an 8.5x11 piece of paper for people without GPS units. Those seemed like the 2 easiest ways to make trails available to anyone with average computer skills.

Lucky for you. What is everyone else supposed to use for topo mpas on Garmin where their coverage sucks?
I don't expect
any map to be 100% correct. Nor do I expect any map to show all of the roads/trails that are actually on the ground. It is obvious to me that you don't really expect this either after seeing all of the work you have contributed here:

I have owned a Garmin 12, Garmin 12XL, Garmin V, Garmin GPSMap60cs and a Magellan Sport Trak Pro in the last 10 years.
I have worked on many GIS projects for the USFS with a gentleman who was on the team that wrote the original software for Garmin maps. This gentleman has also created a special map set for Garmin GPSrs with EVERY trail in the San Bernardino National Forest.
I teach map, compass and GPS classes for the USFS.
My girlfriend was a west coast distributor of Lowrance products for a short time.
Do I need more first hand experience necessary to participate in a GPS thread?
Your experience is very much welcome! Everything I have learned about using a GPS came the hard way- by going out and trying to figure out how to get my device to tell me what I want to know. It is nice to talk with someone who can teach me something new... like you just did with your GPS Visualizer link.

You are assuming that GPX files will not work on a Lowrance 540c?
I :heart: .gpx files as well. I have uploaded many .gpx files, as well as topo maps for ANY Jeeper to use on any GPSr that works with waypoints, tracks and routes. Are you assuming that a Lowrance 540c does not work with waypoints, tracks and routes?

Why does anyone become so "brand specific" (Garmin) that they are not able to see the virtues of other brands? I was honest with everyone in letting them know that although I have never used a Lowrance 540c, I would not hesitate to purchase the unit if I was looking for a GPSr that size.
I have no experience with anything other than Garmin units. That is why I am asking here... to learn first hand experience from those who have it. I really want to know if the Lowrance 540c can do these two things:
1) Automatically generate a route from point A to point B, using roads stored on maps that you can easily download to the unit.
2) For those situations where the cartographers don't know about the roads/trails you use: The ability to download a track or route from saved from a previous trip, from the internet, or even made from scratch on your computer, put said track/route in your GPS and have it route you to where you want to go.
I don't work for Garmin, nor do any of my relatives. I just want to know from someone with first hand experience what GPS units on the market will do those 2 things. The Lowrance Baja 540c is the only GPS unit out there that seems to be marketed for off road use and it always comes up in these discussions. That is why I am asking.
I hope I have not offended you by asking direct questions about things you have stated in your posts. It seems that my goal is to implement on

exactly what you have already accomplished on MJR and I appreciate the very valuable information you have shared.
