To resume, the drivesmart 61 southern europe (SE) LMT-S has restricted voice command, in fact no ASR folder in the .system
below what I learnt and tried to enable the real voice control (ex: "find place" command in english)
initial configuration:
0- gmapprom southern europe + parkopedia & foursquare in map folder
other configurations tested (universal patch):
1- gmapprom southern europe + europe north all (in .system map, map and sd card)
2- gmapprom sourthern europe + City_Navigator_Europe_NTU (installed with map install)
3- gmapprom europe south all + europe north all (in .system map, map and sd card) -> this because discoverd southern europe not the same than south all
4- gmapprom europe north all + europe south all (in .system map, map and sd card) -> this because I read that in full europe models, the system map is north all
5- only City_Navigator_Europe_NTU (installed with map install)
6- gmapprom City_Navigator_Europe_NTU part1 + other parts (in .system map, map and sd card)
7- added ASR lines in the garmindevice.xml -> because read that garmin express read this file to know what to upgrade
=> But for all cases, never garmin express neither webupdater proposed me to download the speech recognition files I was looking for (only the language voices in voice folder)
So even if it possible to use other maps, did not succeed to make it think it is a real full europe device, and trigger the real voice control.
I tought at the end that gmapprom was used by garmin express to know what is the prebuilt map of the device is, but was wrong because sometimes asks me if I would like to download the southern europe map -> what indicates that my device was still in SE prebuilt configuration, so the information must be somewhere else.
I am afraid my problem should require a specific firmware development, like the one some dudes built for nuvi models to enable TTS and other extra features:
