My BT module got wet (its a D4 upgrade one) and now the screen just has the LR logo and nothing else.

Codes said optic message missing, so I assume because the BT is broken, the rest wont work?

Am i right (for once )?

Yes, when mine went the whole AV system wouldn't turn on

Thank you

You can get a fibre optic joiner thing on eBay pretty cheap which allows you to do away with the Bluetooth module if you want to test the theory.

Ordered

Dont expect it to cure the issue pal

What do you think the issue is?

Any pointers much appreciated.

Could be anything pal , over complex system that LR insisted on using ,makes it unreliable and difficult to nigh impossible to diagnose , mine is doing much the same but nothing i tried with the optics made a difference, im ripping mine out and fitting android from scratch, i hope the loop works for you , by the way you can try looping it to test it , youtube ' range rover atereo fix , its easy to try and free

I have just been out and re fitted the BT module....nothing.

So I tried a homemade loop and everything came back on. Still the odd crackle and pop from the speakers, but nowhere near as bad as yesterday. In fact, a bit of fiddling with the loop tube I used and it was OK again.
When I moved the loop I made it crackled again, so I think that is because the light doesn't quite meet up 100% unless I hold it straight, which is no surprise as its an old fish tank pump tube with a slight curve.

So a proper loop might be OK. If not, I will be looking out for your thread on how to change the system!!

But i am hoping its all OK, as I have not had any issue at all with it until it got wet. (The BT module is toast though, it smells burnt. No biggie for me since I haven't ever taken a call on it anyway).

Yay , result , at least you know for sure pal , order a BT unit now ??

I probably will, but I want to make sure that there is no more cracking when I fit the new bypass loop, which should come tomorrow (Amazon deliveries in France are not reliable).

I suspect the amp got wet/damp as well, but is slowly drying out, hence the crackling)

Just to update in case it ever helps anyone, I received the fibre optic loop bypass thing today.

Fitted it and all is well in the world of stereos

Great stuff 👏
