The original 3G map 'activator' was packaged as an MMI firmware update; It worked by just adding/changing one file of the MMI file system. [Subsequent activators are script files which do more work].Dear forumers!
Please tell me somebody, what is the difference between two firmware?
If you applied the original activator, you changed the firmware level from whatever was installed to "HNAV_EU_K0257_6_D2".
Systems with the _D1 level are at K0257_6 and haven't had the original activator applied; systems with _D2 HAVE had the activator applied but MAY NOT BE at level K0257
