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

@pj4mj

Put gupdate.gcd in . system folder and restart nuvi.

Write in hex editor in search number 30 00 30 00 36.
I never search number in firmware becouse i post on other forum to user that i need splash number from all nuvi series 1xxx and users send it to me. Nuvi splash numbers:

old 1300 D1340-00 show nothing
new 1300 D1340-80 show LA and Speed limit

1350,1390,1490 D1340-50 and D1340-65 Show LA and Speed limit,JCV

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.
