It just says SD on the card though Lars and when I went and looked at the reviews plenty of people actually bought it to work with older tomtom's and garmins and say it worked flawless.
Maybe the product description is wrong?
That's the problem with Amazon and eBay. Often they just use any old generic picture to illustrate a product. It needs a bit of detective work! An email to the seller should resolve any doubts, but maybe even THEY don't really know.
If you ask them to actually LOOK at one and it doesn't say "HC" on the label, it should be OK.
From the picture and the reviews, I THINK it will be fine. No promises though!
Also I need this question answered....The maps I "already bought" are already divided into three zones...All I need is western Europe...Western Europe is just under 2GB thats fine BUT do I need to transfer the maps from my CURRENT SD card before installing the new maps? Does the update need the old maps to write over?
There are several ways of doing it. If you already have an older map on the destination card, then Home SHOULD remove the old map first and then install the new one.
But if you have already moved the map off it (or in your case it's a new map and it was never on that card) then Home will just add the new map.
But if you had added any of your own POI files onto the old map, Home won't be able to transfer them across to the new one if the old one's not there. It SHOULD move your settings (Home location etc.) across too, but it often messes that up and you have to enter them again anyway.
Personally, I WOULD move the old map (or everything) across to the new card first, just so you can check everything works before you do the update.
And to repeat... so long as you have that Windows-created backup, you should be able to recover from any disasters!
