This is not my original, I just modify and integrate to make MOD more perfect.
The two mods come from:
Immersive HUD (LUA)
https://www.gta5-hub.com/scripts/immersivehud
ExtraHUD [LUA]
https://www.gta5-hub.com/scripts/lua-extrahud

In order to show that this is not my work, I signed for them.
Please forgive me if there are any offensive places in my revision and integration.

MOD Pre demand:
Install Script Hook V: http://www.dev-c.com/gtav/scripthookv/
Install LUA Plugin for Script Hook V: http://gtaforums.com/topic/789139-vrelhook-lua-plugin-for-script-hook-v/

INSTALLATION:
Select the desired version and unzip the scripts folder to your GTAV, overwrite if asked.

ExtraHUD.lua
local ampmclock = true -- change to false if you want to use 24-hours clock
local kmh = true -- change to false if you want to use mph speedometer

Modify and integrate explanation:

Modify the control:
* (Keypad*) - Show menu + hide/show small map
(Hidden small maps also hide the HUD UI that belongs to "ExtraHUD" date, week, and time.)
Numpad 0 - Hide Menu
Direction arrow keys - Adjusts the HUD interface when the MOD menu is opened.

Note:
The date, week, time, HUD now including the speed and the engine can not be adjusted, because it is part of "ExtraHUD", but can be adjusted individually. In addition, "ExtraHUD" does not have any key operation, and will be used directly after installation.

Add seconds to show.

Added a HUD integration version - remove the HUD menu version, directly reduce the configuration file, so there is no menu operation. However, it also has the dynamic function of automatically displaying/hiding health values ​​and body armor.

Now all versions have completely repaired the bugs in the top right corner where the money is not displayed or has been displayed. Now the money amount is automatically displayed/hidden normally after spending and income.

Now you are free to set the 12-hour/24-hour system and use the modifier to adjust any time period without any problems. All HUD UI screens can display normally.

Sorry, I don't speak English, so the instructions are from Google Translate.
