SD card for entire N. America maps
I've been lurking for a while and found this forum interesting. I recently purchased a 52lm and have a question. I have seen several vendors on ebay selling current SD cards with North America maps. I travel to Canada frequently and the 52lm contains only the lower 48. If I purchase a card with North America maps will it run on the 52; and what do I do with the card when I update maps via Garmin Express.
