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

mkral, as said twice above, showing fail is quite normal usually and not a problem in real life usage especially for the splash. The 'Fail' shows only because the checksum has not been properly calculated and if that's corrected it'll show 'Pass' instead but that will change nothing as to the functions controlled by region 16.

If it really bothers you but you don't know how to re-calculate the checksum for the bin file you can do it automatically by opening the bin file in GIR_Editor then re-saving the file without changing anything and flashing it back to rgn 16 [0x10].

Still relevant, revived my garmin nuvi 1200 and 1250 series GPS devices. I never understood why Garmin was witholding features to make a couple more bucks

@ustass
At base of post #1 is a link to [Only registered and activated users can see links. ] which has all the patches for all 1xxx devices in one universal SD flash pack and a guide for use. Absolute easiest way to do it.

@Fery Apriadi
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.

It means it's an Asian device and as you've now realised not suitable for this mod. However there is nothing you can enable because it already has JCV anyway, which was lacking in most EU/US releases of 1350. ID device spec's:

Asian models were/are often higher spec'ed than US/EU equalivents.

I think all 1xxx from 1100 to 1490 use the same processor from Cartesio ARM so performance should be the same across the series. The MTK reference is in regard to the GPS chip only.
