SD cards...
 

BIG Breath - especially with diving into a thread such as this that to me, at the moment, seems like a foreign language (as does Spanish after 5 lessons....).

Long story short, bike is being shipped from New Zealand to Los Angeles, we then plan to take 11 months riding South through Central and South America from June. I have the Gamin maps for North and South America. Maps for CA is my confusion.

So;
first step to loading CA maps onto my Garmin is to buy an SD card, correct?

I have SD cards for my camera but they seem a lot bigger than what will fit in the Zumo XT (Zumo has microSD cards). I see that the Garmin maps I have purchased you can remove a small card out of the SD card that they have. Second question - are they a special SD card as my camera SD cards don't seem to have that?

Third question, if I need to buy an SD card to download CS maps what size card to I need (I have 1, 2 and 8 GB cards)?

Those are my questions for now :-)

Thank you

Hi Mike, sorry no one's answered your questions yet.

Installing maps into Garmins can be mind boggling but post Montana series is a lot easier than it used to be.

You Garmin will run a miniSD card - like you stamp-sized camera card but size of a fingernail or a phone SIM.
As you have found you can get big-sized holder/adapters into which a miniSD will slot.
That holder/mini combo could be used in your camera or other big card devices, if need be. It's the same tech afaik.

Go big. Even 8GB seems small.
And go fast too. The other month I updated my old mini SD - class 3? - to a class 10. Much faster response, even if Garmins aren't known for that.

Have we had this one yet?
Who knows but recommended by an Africa pro.

Yes, I think I posted about these sometime ago.

I've been using the North Africa Topo for 5-6 years now. The latest update isnt very good on screen via basecamp but works well enough on the device.

Another option are the Open Topo Maps but the way they rendered the map males using it on a Montana almost impossible as the contour lines are thicker than the pistes
