Thread: How to add waypoints to a Lowrance Elite7?

Try putting it in on google earth and see if the longitude is correct.

longitude has something to do with the equator. What hemisphere are you in? Northern of Southern? Give us a sample, You can leave off the last 2 digits if you are a worrier.

JB .... I use this converter website : GPS Coordinate Converter, Maps and Info

Seems as though all the "website" GPS coordinates I can get are in Decimal Degrees, and my Lowrance Elite 5DSI will only accept the "GPS" long/lat numbers shown in the conversion table. I punch them in manually, and most are pretty accurate, some being dead on.

I tried the Decimal Degrees numbers on my unit, at first, and no waypoint icons appeared. I took those same numbers and put them in a mapping website that uses the GPS Lat/Long like my unit does and the waypoints popped up somewhere in the deserts of the Middle East

My pills must be working. Latitude is relative to the equator and longitude is relative to the Prime meridian. Dats why things end up in the sand sometimes. I stand corrected.

Yeah, but .... I was using the Decimal Degrees digits, and just clipping off the last digit, thinking that would only change the location by a foot or two .... NOT showing the waypoint on the OPPOSITE SIDE OF THE WORLD

Thanks to that converter, I have over 200 waypoints ... all manually entered from right here in my living room (thanks to an extra power/td cord & portable jumper battery).

I can add them if i use the GPS converter. Sure wish there was an easier way than having to manually enter them all one by one. I'm sure there is... I'm just not smart enough to figure it out.

There is an "easier" way ... but, some programs are "pay to play".

There's GPSBabel (free download - donations accepted) ... but you'd probably have to research which file types your unit accepts and then punch all the coordinate info into the program on your computer, then download it to a SD card and put it in your unit, then figure out how to make the unit's program download the info (from the card) into its memory.

I just used the first "converter" program I found, which happened to be the Boulter website. It worked, and because I have the capability to sit on my couch and punch the coordinates into the unit ... I never bothered to research a "bulk" uploading type of program.
