Maybe a stupid question, but...
 

Hi :-)

Used to use paper maps only and a lot of nice talking and asking too...;-)

BUT....now I got myself a Garmin Zumo 390L for my next tour around the Stans
summer 2018.......

( will do a training tour up north for a cold beer in Murmansk summer 2017)

....for The Stans, would you buy a - like 200 gb memory card, keeping everything on card or several smaller 32 gb..?

I wil be travelling from Denmark - over Kleipeda- Minsk- Kursk- Volgograd ..into Kaz, Uz, Tad, Kyr, back from Almaty Kazh. ...

How much memory would I use, keeping on one card, or more,and not download and delete, as I would like to have the hole tour planed with waypoints and tracks done from the start.

Thanx :-)

I don't know whether or not the Zumo will read the maps if you put a lot of separate maps on to one card then place it in to the Zumo. It might confuse the Zumo. I could not get my Garmin Montana to do it. Although others might know of a way.
If you can all the maps together (i.e. in one package/download) rather than getting them all as separates then it would be better.
I got my maps from an open source website Free worldwide Garmin maps from OpenStreetMap
and placed them on smaller 4GB SD cards and just swapped them during my trip, if you get and overlap of the maps its not too much of a problem.
Also if your card fails then at least you have not lost everything

tracks and waypoints are pretty small. Couple MB's. The maps are a different matter. This varies greatly. Some Garmins allow for custom maps but don't handle them very well. Buy custom maps I mean scanned in paper maps. Whatever the TIFF file size is that you export it in (the image needs to be georeferenced first) is what you'll end up with.

If you're used to paper maps your maps can be pretty simple. Vector maps can be large. How large depends on how much data they pack into it. 90% of it you'll likely never use. For that reason I don't use vector maps typically.

Thanx for your replays and ideas....:-)

I will probably use 4 or 8 GB cards, if something should happen or the Garmin suddently cant read the map etc. I will split up my route i smaller parts, doing some overlapping.
Testing it on my trip up to Sapmi this summer...

(Guess I will still buy papermaps ( got them for memories with all the points details written on them - always nice to spread them out on the table later, and remember the tour and places)

All of western Europe is something over 2 Gb ... think you will find your trip will easily fit on a 32 Gb card with a lot of room to spare. You might even get it all into a 8 Gb card. If you have basecamp/mapsource and the maps you can select which maps you will need and see what size they are by downloading them onto a card in a card reader on the PC.

I use paper maps too.. I write on them in pencil - much easier to make notes on than some electronic device.
