Thread: Enable features in your nuvi 12xx, 13xx and 14xx - JCV, LA, TTS

so a 1300 will not have JCV if you put the JCV file on the 1300 after applying the firmware upgrade?

it will have everything: JCV, LA and speed limit - the formware changes splash screen to 1340-50, so everything should work. At least, it should work with EU, US and Australian maps; Asian maps seem to have an issue that requires changing the whole firmware.
