I purchased Garmin City Navigator Europe 010-10680-50 on an SD card and my Nuvi 3597LM recognize it perfectly. I can see the EU map, but when I plug it to Garmin Express nothing shows. It does not see the pre-installed EU map on the SD card. It only sees the map pre-installed on the Nuvi.
Later on I want to be able to buy updates, possibly a life time update, but it won't work if Garmin Express does not recognize it in the first place... And the device does not have enough memory to contained both NA and EU so I don't mind keeping it on an SD card.
Secondly, I'd like my product to be registered but again if Garmin Express does not recognize it it won't happen either.
Any thoughts?
fyi: I'm on a MacBook-Pro
