Every gps I've owned or used, has choices in the Settings menu for DD, DMS, etc.
Bought a HN6 a while back and just getting to know it.
Now when we were cruising in the yacht all my navigation was in DMS and the Hema is in DMS and all my maps are DMS.
Joined CMCA and they have a thing called Geowiki that lists dump points etc. Their co-ordinates are in DD.
Is this becoming more common?
How many use DD for their navigation?
Can my Hema be changed to read in DD as well?

Hi
Google Earth and Maps use DD, but will accept other inputs. This may eventually make DD the accepted default.
We saw some very interesting places by not realising that the Camps 5 book was in DMS an our Garmin Nuvi was still set at DD.
Cheers
I've been using DMS for about 70 years - and don't expect to change!
If you are going to change, why not go to radians!

DMS are too hard to accurately position on a map and impossible on a street directory.
i use UTM - Eastings and Northings. Using those, it is extremely easy, down metre accuracy, to locate or position oneself on a map.
The grid on a topo map is in multiples (or fractions) of 1000 metres and the numbers refer to Eastings and Northings. Ditto on a street directory (if you young blokes have ever seen one )
I used to use DMS or decimal when I worked with hydrographic charts (plotting submarine cable positions or trawlers).

When I was a baggy green-skinned animal with black feet, we used mils for navigation, bearings etc.

I personally use DMS, but prefer UTM myself(Eastings and Northings as P38 says..) easier to estimate how far in a straight another point is in a straight line compared to degree values.
But I use DMS because of the lowest common denominator rule .. that is the device that can only show degrees(ie. not E and N values) so it's easier to quickly determine relative location.
I don't have a Hema. looked at getting one but found they cost too much for what you really get .. So I just buy their maps as needed and as they get updated with newer data or more detailed info.
I still use OziExplorer mainly on PC, and Ozi Android now for mobile mapping. Used Ozi WinCE for years too.
Doing a lot of research on the HEMA hardware, they run two different programs, depending on what you want to do.
Some iGo or whatever street nav app, and a cut down mobile version of Ozi for the 4WD mode.
So the answer depends on which app, or mode you mostly use.
if it's the 4WD mode(ie,. non turn by turn mode), then you're using Ozi and there are settings to use whatever mode you prefer DMS, DM or D.
In this instance you go to Settings -> General(gear wheel)->Operation tab .. you should see the Position format box up top there.
Full fledged Ozi has many different position formats many that you wouldn't use(eg. Swiss or Swedish Grid, and other formats for foreign lands and maps), and you wouldn't expect those non Aus related types to be included in the HEMA.
But even a stripped out version should offer the 3 various Degree formats(D, DM and DMS), and most likely the universal UTM too.
hope that helps.
