Release Date History for City Navigator Europe Map

Up through version 2011.30, CN EU came only in the NT version. Garmin introduced the NTU map with 2011.40. This version used Unicode text encoding for extended language support. Older devices don't support Unicode, so Garmin continues to provide the NT map version for these older devices. Both NTU and NT versions were released on the same date for CN EU 2011.40 through 2014.40. After 2014.40 Garmin announced they would release only 2 CN EU NT versions per year.

The CN NA map still only comes in a NT version, presumably because most North America customers speak English, Spanish or French which can easily use standard text encoding.

We are not sure when the device support for Unicode started, but think it was about the time of the 3xx0 nuvi models and possibly some of the 2xxx models (around the 2011 time frame). Garmin never provided firmware updates to support Unicode on the older devices like the 1xxx, 7xx and 8xx models
