If the ID will be checked by devices, is there a possibility to change the ID to a lower (<2200) value?

Theroretically, this was done for cityXplorer maps, which always require .unl file. In that case, maps were changed to obtain ID 800.
In other, "normal" maps, this is not necessary, as you can fully unlock the map by available unlockers.

Caty,
Thanks for the info where to start with. At this point I have read the logs and I am little undecided on the versions to start with. If you had to start from scratch which version would you start off with Mapsource v6.16.2+ Special+MapInstall v3.14.2 patched or Mapsource v6.16.3+ Special+MapInstall v3.14.4 patched or something else?

does this gma firmware thing affect most models or only the latest generation like the colorado, oregon, new 62's 78's, etc?

Use the latest version, there is no difference in unlocking, if you want to have a difference you should install old 6.13.7.
But we have nice unlockers now and patches
