Thread: NA NT 2016.10 Revision, uConnect 8.4N RB5 (2011 Model) Questions..

Hello all,

I am attempting to follow this guide;

Code:

Please Login or Register to see the links

So far, I have concluded that I need the following, according to the guide above, please correct me if I'm wrong;

Mapset (Post #1, CNNAM NT 2016.10_Orig_pc)
JCV File (Post #1, D3191170B.jcv - SplitScreen Full version Nuvi 24xx 25xx - I would prefer FULL screen, but the guide above specifies D3191170B.jcv?)
ASR Files (Post #3, ASR-3790: Part1 | Part2 | Part3)

Am I correct in believing that these files are all compatible?

I have unlocked the mapset using gimgunlock, then installed the mapset to a USB Pen and ended up with what I believe is an unlocked gmapprom.img. I believe the guide above says to use locked maps, as they will be unlocked during install.

As far as the following;

gmaptz.img (time zone file?)
gmapbmap.img (base map file?)

Are these necessary when updating? If I do not include them, will the new mapset utilize the already-installed timezone file and base mapset?

Assuming that holds true, I will soon have the following structure;

└───Garmin
. │ gmapprom.img
. │
. ├───ASR
. │ 05DX0YRK.SRX
. │ 05DX0YRL.ASR
. │ 05DX0YRM.ASR
. │ 05DX0YRN.ASR
. │
. ├───JCV
. │ D3191170B.JCV


Moving along, I also need an unlock code. I have employed JetMouse v1.5 for this. I believe I will input the FID 3767, and my Unit ID (to be determined soon..), select custom mapset, click generate and I should have the unlock code my uConnect Garmin will ask for upon installation?


My biggest concern is making sure all of these files are compatible, and that the above is correct, so please correct me if I am incorrect in any of the above


ALSO, to any uConnect 8.4N RB5 owners out there; Garmin Firmware Update? I have 3.20, which looks very outdated. Does anybody know how/where I can update this? I believe the firmware is specific to the uConnect Garmin unit?

Thanks in advance for any help, big or small!
