Difference between downloads & SD card map purchases

Hi all,

I've recently bought a 67i from an authorised reseller, I have gone on to purchase the Topo Pro v3 Great Britain maps from the same reseller, and they advised me to purchase the SD card version as they said if I was to replace the unit this can be moved to a new device.

The SD card arrived and it is all working well.

I am going hiking in the Alps next month and wanted to purchase the Alp Pro, but it appears that is only available for download, can I just check some assumptions:

1. I will need an SD card to put the Alps Pro maps onto.

2. The Alps Pro downloaded maps will be locked to my current 67i if I were to sell it in the future to upgrade I may as well include the SD card with maps as they won't work on any new device.

3. The official Garmin SD Card with the Topo Pro Great Maps WILL transfer to any new device.

Thanks in anticipation.
