Since I did the BT bypass all has been well in the audio dept, but this morning got the flashing button and Land Rover logo-nothing else.

Been pulling the fibre optic leads out one by one, and the unit below has the fibre optic light going in, but nothing coming out. Is that the issue?

(I did try to bypass that module but it still didnt work, but then it moght need that module to work).

That's the TMC receiver, I wouldn't have thought it was un-bypassable but you never know... Has it got power to it?

You were right-I did it wrong the first time! Now working-thank you

Any idea what the TMC does?

Traffic Message Channel-I dont think I need that anymore.

I always found it worked better in EU than UK, it's an overlay on the Nav. screen so even if you're still using the Nav. it won't / shouldn't cause any issues.
