Adding European Maps to GPS

[BJG577]

I live in Canada and will be traveling to Spain. Is it possible to add a map of Spain on either a TOM TOM or Garmin device?
Also, about how do these maps cost?

You can download free OSM Maps for Garmin devices from (Click HERE), you can add new maps to the existing ones on your satnav using Garmin Basecamp, or download a version that can be placed directly on a microSD card (this will replace existing maps on the microSD card)
