Hello Ted
I am not sure what you are asking but lets have a look see..
Your unit appears not to have any internal memory but it can accept micro sd card so ...
From OSM website, select the map tiles you want and make the request by entering your email address.
You'll be notified by email of request acceptance then with another when maps are ready for download.
Choose the IMAGE option- one single file that you just copy on your micro sd card.
- Create a folder called 'garmin' on micro sd card
- Copy gmapsupp.img map image in it (that OSM sent you)
Job done
next one on you! (where's my barrel BTW? !!)
max 1000 waypoints - that's a bit limiting
BUT read re: custom POI below
electronic compass- that catches many out- remember to go through the calibration process each time you remove the batteries/travel with it switched off far etc etc
When I'm out there, it's a daily ritual to calibrate it while my engine warms up. It takes no time at all.
50 route storage
Track logs 20 with 10,000 points
Hunt and fish calendar useful if you enjoy fishing as it will give you good/best times to fish from your (or a projected) location.
Barometric altimeter- useful when watching out for weather changes. (or look above you and spot the dark cloud!)
Unit sealed to IPX7 - so no worries about the rain but remember that it doesn't float!
Custom POI capability- that is a very useful (IMHO) option as you can store a huge number of gps points of interest
without using up the units own way point memory.
As far as
micro SD cards (remember that one of your cards goosed in Africa... still waiting for that barrel of
too....) I find it best to have a few small ones rather than the more expensive larger ones.
I use
San Disk 4GB micro SD class 4
As the OSM maps are open source (no licence needed) you can always put the same image onto two separate micro SD cards in case one goes wrong -
(belt and braces!) or have it in your notebook or portable usb stick/hard drive if carrying one.
hope this helps- still unsure about the question
if not best pm me your telephone no.
