k.akagi Offline	Hello. Latitude and longitude that appears when you import the waypoint of Reef master to export to LOWRANCE is different. Please tell me.

Matt Offline	Hi, Can you please describe exactly what you are doing, and what results you see? i.e. where are you creating the waypoints, what format are you exporting in and how does the exported waypoint differ from what you expect. thanks, Matt

Matt Offline	Thanks - interesting, we will look into it. Could you also send your GPX file through to This email address is being protected from spambots. You need JavaScript enabled to view it. and let me know which waypoints are affected? thanks, Matt

Thanks for the file.
I've taken a look, and I don't see anything wrong with the way RM is exporting that waypoint. Here is the relevant fragment of the GPX file:

<wpt lat="31.567" lon="131.400233333333">
    <time>2014-11-07T12:33:44Z</time>
    <name>aji</name>
    <sym>circle,blue</sym>
</wpt>

Just for my own sanity, I also ran the decimal values through some other coordinate conversion tools, here is a link to one example, where you can see that the decimal value in the file converts correctly to the original coordinates that you posted: http://boulter.com/gps/#N031.34.020%20E131.24.014

We do a lot of testing for coordinate import/export, including round-trip tests where we chain loads & saves in different export formats, and I think in this case the error lies outside of RM.

I haven't tried importing this file into a Lowrance unit yet, but is there any possibility that your unit is set up for a geographic coordinate system other than WGS84? This shouldn't a difference to import (the GPX format is always expressed in WGS84), but it would make a difference to the way the coordinates are displayed on the unit.

thanks,
Matt
