How do you convert a Garmin mapsource file to a Lowrance file? I have waypoints on a mapsource file and I need to get them onto a Lowrance GPS unit. Where do i start? Thanks!

Try G7toWin, which is compatible with both of those waypoint file formats.

Another good freeware program is GPSTrackmaker

will these work if someone has sent me the Garmin file via e-mail and i need to get it into Lowrance? I use Garmin and Mapsource but need to get a file into a Lowrance unit? I do not have the Lowrance unit and would like to send them a file that will work. Thanks

It should work. From either program open the Garmin file and then save it in Lowrance's format (USR I believe).

Or you can do it right on the web without installing anything

I apreciate you guys helpin me...out of these three sugestions i think the last one was the easiest...now lets see if my driver can open the file and put it in our race GPS. thanks!

I have a lowrance fishing hotspots SD card...long story short my lowrance got stolen and I bought a garmin unit...will the garmin read the lowrance format or do I need to convert it somehow?

You'll need to convert it. Check out the links and advice in the previous posts above.

this thread was a little old, are these still the easiest ways to convert them or has something new come out?

I believe they're all still valid and http://www.gpsvisualizer.com/gpsbabel/ is easy (nothing to install). In addition GPS Babel is available to download as freeware (link)

ok thanks. Which garmin output selection am I looking for? It lists 3 or 4 options....lowrance only has one it looks like for input?

GPX is supposedly the universal GPS data format and most newer Garmin units support it. What Garmin model do you have.

Note that the lowrance fishing hotspots SD card may have DRM and can't be copied.

i have a garmin gpsmaps 540s.

i did the gdb extension, i didnt see the gpx listed as an option?

It's shown as GPX XML

OK I had a look at the manual and it appears that you'll need to use Garmin's MapSource program which should have been packaged with your GPS. See page 38 of the manual under the "To transfer data ..." sections.
