L322 Radio Issue

Hello All I’m relatively new here and was wondering if someone could help,

I have a 04 Range Rover L322 TD6 Auto with the legendary Touch screen that only displays the Land Rover Logo,

having read and watched all YouTube videos and forum threads i had no choice but to start my own,
As with many others the On/Off button blinks with a orange light.

the car is new to me I had a P38 before... I bought some Most connector fibre optic loop connectors of eBay. I have looped the Bluetooth module because I never use it and do not mind if it doesn’t work. I wasn’t getting a light after the TMC module so I linked that unit out as-well. Still Orange light flashing.

somebody had left the Fibre optic cable unplugged from the Harmon Kardon unit which was very difficult to plug back in but this unit seems to be repeating the signal fine.

my question is how many modules
.

There's also a tv module

Hello

I Believe I have 5 modules?

a Bluetooth phone kit module...

Harmon Kardon module (not sure what this does)

Audio Amplifier not to sure on this either

A Smaller box which I believe to be not repeating the light which has TMC on it

and I can’t remember the fifth box ?
