That pack is universal for all 4 US/EU 1xxx HWIDs only. You might have an Asian version so check it's HWID before proceeding if you aren't sure what it is. From initial post:
How to check which chipset I have? Enter diagnostic menu by pressing battery icon for 5 seconds, press "next", then "start test" and "more". The first 3 entries show which chipset you have:
-regular chipsets in Europe and US: B0971 (for 12xx series) and B0972 (for 13xx/14xx series).
-MTK chipsets: B1104 (for 13xx/14xx series) and B1106 (for 12xx series).
Don't use the flash pack if your nuvi has a different HWID, it should be either 0972 or 1104.
