Well its pouring down here so in my wisdom i shut my self in the rear luggage space, and well im blowed its comimg in like a stream.

There's a rubber bung in the bottom of the compartment where all the modules sit, you can remove it to let the water out again.
Be worth checking the spare wheel recess as well.

Amazingly spare wheel well is dry, possibly the last couple of days weather has done the damage. Any links to a new seal or is it LR only item.

The seal is LR only, best place to get is via Dan@Duckworths, forum sponsor. Just send him pm with your requirements.

Had a good look today and it turns out the tailgate seal is OK, water has been getting in thru the side trim so i have removed it fitted new clips and sealed it, all seems to be ok now after 20 mins of hose pipe abuse.

Latest update, Being a stubborn old sod i thought i would have another go at it today. I stripped the tv/entertainment unit and solder two wires to the PCB, then connected them to the loom the other side of the blue connector. And hey presto we have a monitor again. Next job is the radio, got it working but only for 5 mins ( switch it off and then on it works for another 5 mins ) I will keep at it

Apart from the three plug in connectors on the amp i noticed there is a aerial type connector should this have something connected to it ??

How do i establish if my amp is the problem OR the BM54 radio tuner to my no noise music system?? Help please

Although there is an aerial connector on the DSP unit nothing is connected to it.
When your radio works, press menu on the screen buttons and go to "Systems menu", you should see DSP highlighted on the screen.
When your radio stops playing go to the same screen and see if DSP is highlighted as before.
I have a suspicion DSP won't be highlighted in which case your problem is with the DSP unit not the radio tuner.

Cheers niceday for your reply. im going to attack it again today, no doubt more help will be needed Thanks Brian.

DSP is not coming up on screen, does anyone know to a amp for sale?

Have you tried taking the casing off the DSP and looking for water damage on the rear of the sockets on the top.
It's worth a go. If you find any dubious connections onto the socket it may be possible to bye-pass the connection and take a cable outside the casing to connect onto the appropriate harness cable.
You could always do away with the DSP as per this,
