Etrex help

In your picture the Etrex is set up to receive Latitude and Longitude in the Degrees and Minutes, in this format :-
N 41 can be any number between 00 and 89 (degrees)
46.208 can be any number between 00.000 and 59.999 (Minutes)
W122 can be any number between 000 and 179 (Degrees)
52.169 can be any number between 00.000 and 59.999 (Minutes)

You need to change the format of your Etrex to receive Degrees rather than Degrees and Minutes

Take a look at the 'Formats page (Click HERE), your Etrex is set to the format on line '2' but it needs to be set to the format on line '1'



You need to change 'Position Format' to Degrees (hddd.ddddd)

 

Yes, while 'Position Format' (the top option) is highlighted in Orange, press the round Enter button, this will show a new screen, you need to select the hddd.ddddd option as shown in my previous post

 

The GPS does not record Track data while it is off, but it will record Track data all the time it is on, even when it isn't moving, it will also record in-doors but as the signal isn't so good, it is less accurate so the Track jumps around to where it thinks you are (even when it isn't moving)

You can clear the current Track data with :-
[Select] Track Manager > Current Track > Clear Current Track

 

Yes, you could say they are errors, If you placed your GPS at the summit of Mount Shasta for an hour or so you would get the same pattern of 'jumps' but they would be closer together because the GPS signals are better up there with less errors

If you select Waypoint manager you will get a list of Waypoints on your GPS, You can select a single Waypoint (in orange) and then display details of it using Enter, when you have the details of a single Waypoint displayed press Menu to display more options, e.g. :- Delete, Change Photo, Average Location etc. , then select Delete

Do you have the User Guide for your Etrex20?, Delete Waypoint is on page 2

When you 'Go To' a waypoint there are several options you can choose from to decide how you get to the Waypoint, e.g. by car, hiking (walking), Direct etc, if you select Car your GPS will calculate a Route following roads on the map and draw a purple line along the chosen roads to show the Route, if you choose hiking you will get a purple line showing a Route along footpaths on the map, in your picture the 'Direct' option has been selected, in this mode no calculation is done and a single purple line is drawn on the map starting at your curent location and ending at the 'Go To' waypoint as if you was flying a 'plane or was in a boat

You can turn off the purple line by selecting 'Stop Navigating', this will turn off the 'Go To'

 

Please Note that the following images are from a GPSMap64 NOT an Etrex20, so they may be different to your screens :-

Fig1 - - - - - - - - - - - - - - - - - Fig2 - - - - - - - - - - - - - - - - - - Fig3


Fig4 - - - - - - - - - - - - - - - - - Fig5 - - - - - - - - - - - - - - - - - - Fig6

Changing the way the purple line is drawn is a bit complicated, Your Etrex20 has a set of Profiles, each Profile is allocated an Activity, like Driving, Walking etc. so if your current Profile is set to driving, the Routes (and the purple lines) will only be on roads, if your Profile is Hiking your Routes will be on paths

On my GPSMap64 you can change how the Purple line is drawn like this :- If I Go To a Waypoint and get a straight line (Fig 3), I can press 'Find' to get Fig 4 and then select 'Change Route Activity' From 'Direct Routing' (Fig 5) to 'Automobile Driving, I then get a new purple line like the one in Fig 6

I know you don't have a 'Find' option but you may get the same options with the 'Where To . . ' screen, you could then select 'Change Route Activity' and go from there
