Disclaimer:
No talks of piracy, illegal links to download map files, fraudalent practices in obtaining GPS units etc. This is the guide to update your Garmin maps on your 8.4N RB5.
Use the following at your own risk; I am not responsible for breaking your system. I have come to realize though that this process mainly messes with the Map files, so if you screw up anything technically you can redo the process to fix it, it doesn't mess with the underlying Garmin software so that still gives you access to fix issues. The links below are not mine, again use at your own risk.
Using this method you can get quarterly updates for a flat one time cost of buying a GPS unit.
P.S. no you do not need to buy a brand new unit, you can buy broken units, as long as your PC can read and detect the GPS you are good to go (i.e. screen cracked units on eBay for cheap).
Tools required:
Garmin Nuvi LMT with ASR for CTP2012/2012.5 (3490/3590LMT/3597LMT guaranteed to work - 3580LMT reported to work)

gimgunlock
JetMouse
Garmin Express
8GB+ USB Stick (the systems are very picky about the USB drives... if one does not work try a different one... slower drives works best)
Reported working drives:
SanDisk Cruzer 8GB (CTP2012)
Lexar S50 8GB (CTP2012)
Kingston Digital 16GB DataTraveler 101 G2 (CTP13)
Kingston Digital 16GB DataTraveler 111
CTP2012 / 2012.5
1-Copy the Garmindevice.xml from the nuvi onto your USB stick to the folder Garmin/
2-Run Garmin Express
3-Download CN NT 2015.30 NA update
4-Garmin Express will download the files to the USB stick in folder .system/, keep only the following files/folders:
.system/ASR (folder+contents): *******0.SRX to *******3.ASR (only the first 4 sequential files)
.system/gmapprom.img
.system/GMAPTZ.IMG
5-Rename .system/ to Garmin/
6-Create Garmin/JCV (folder)
7-Download: 2015.30 Full Size JCV http://download.garmin.com/support/2015_30/NA/JV/D3060160A.JCV and put it in JCV folder (this download is not required if your Nuvi version downloads the Full Screen JCV by default)
8-Put car in run mode (with engine on or not)
9-Turn all unnecessary features off (i.e. A/C)
10-Leave your radio on (needed to recognize a USB is plugged in)
11-Goto the Navigation screen
12-Plug USB stick into vehicle, it will start Validating the USB stick
13-When the update prompts, follow the menus, when it askes for an unlock code, use JetMouse (usage not explained here)
14-Let the system update (1-1.5hr process, if engine is not on, the car will shutdown after some time, to prevent this cycle the off-acc-run button so it resets the idle timer)
15-Once it reaches 100%/full completion bar: It will either give a maps updated successfully message or reflash failed message. Just verify that the maps loaded fine, but you should be GTG.

5-Rename .system/ to Garmin/
6-Run gimgunlock on GMAP3D.IMG and GMAPPROM.img (usage not explained here)
7-Create text files GMAP3D.unl and GMAPPROM.unl and paste unlock code from JetMouse (usage not explained here, most state to exclude this step, but it had no negative effect on my system leaving it in the Garmin/ folder)
8-Put car in run mode (with engine on or not)
