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
