Hello & Welcome,
I suspect that you will need to purchase maps for your travels, and I would recommend the pre-programmed microSD/SD card version - so as to not disturb the current maps installed.
You can order that card at the following Garmin web page, Just make sure you order the correct version.
NOTE: Based on the cost of just the maps, you MAY find that it is more cost effective to purchase a separate unit for your travels.
Please let me know what you find.
Thanks, ***** *****
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved?
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
