On investigating today I found this:. Can anyone tell me what it is telling me and what it does? Thanks.

MOST Networks in the Car Industry

MOST Technology is a widely used multimedia network among European carmakers most notably BMW and Volvo

BMW - is a member of a core group responsible for the development process of the MOST technology. Therefore, BMW integrated the MOST into almost all BMW car series as a transfer network for audio signal. MOST technology is used from low-end vehicle variants with a single radio unit up to high end sophisticated navigation system with 14 devices (e.g. BMW iDrive) connected to the bus. The topology of the network is a passive MOST star with a 5-port in-line coupler placed in the trunk of the car.

The reason for implementing MOST Technology as a star - is that the changes in star topology (adding devices for example) are cheaper than when adding them in a ring.

Pcourtney. Many thanks for your reply, I have a basic understanding of the LR MOST system, what I would like to know is what are the boxes telling us. Are they what the system has in the fibre optic loop and are they indentifiable?

Sorry not much help to the OP, but surely the above isn't right -- for example the simple fix for most (no pun intended) that freeze is to remove the Bluetooth module (likely to suffer from water ingress) and 'loop' the fibre connectors - this would suggest ring and not star wouldn't it? Current: 2011 FFRR Vogue SE 4.4 TDV8

Bushy30. The n/s/r compartment housing all the gagets is absolutely bone dry. The "Hidden menu" hack self diagnostic system states that it recognises 8 mpr, however the system like many other members posts state, it has no radio volume knob operation, no selection of CD,AUX,TV/DVD, telephone or voice control and no rear camera. Plus the TSD has the logo on it. I have traced the MOST fibre signal and it is completing its circuit fully also completed a hard reset a number of times and the battery is a quality branded one that is fully charged and 1 month old. The fault literally just occured during the time of parking up and shopping for about 40 mins. I was curious as to what the screen was telling me about the system status. Everything was working 100% prior to the issue occurring and as I am in the process of preparing the FF for disposal I need to get it fixed. I do not have an iid tool, just a Foxwell 510 NT which does not "program". I will book it in somewhere to get it sorted if it does not right itself. My guess is a glitch and it has "forgotten" it has the now non operational items. Happy days. Thanks.

Apologies, I hadn't realised you had an issue -- just thought you found a screen and wondered what it was telling you.

I was only giving an example of what I believe is a MOST ring or at least daisy chain, as opposed to star!

If you do have an issue you may find this helpful:-

When you say you have traced the fibre signal and it's completes it's circuit, can I just confirm that you have light at all connectors from the start (I'm assuming that's the TSD) to the units in the boot and back around again? 2011 TDV8 Vogue SE

Bushy30 thanks for the link. Apologies for lack of clarity.

dennij. Indeed I do have a complete fibre loop flashing red light at all units and there was NO symptoms or issues prior. I truly believe that the system has lost it's memory of what there is fitted. The screen can be switched between its options via soft and hard keys but various items just will not work. So a reprogramming looks like the only way to go.

@Classic, you are not alone!

End of May I posted a thread with the same issue as you describe.

No replies though.

@RichM63. Just read your post from end of May. My RR symptoms are very similar and I note you changed the vehicle battery recently. Did you wait for the car to shut down before disconnecting the battery? If not, it is very likely that the CCF files have become corrupt, hence you have the issues you have. I did not change my battery, the problems just happened! Tomorrow I am speaking with someone I used to work at LR with (now I have a contact number) to see if he can assist. Regards.

I await your findings in anticipation.

(yes I did await a full shutdown, doors shut not locked, bonnet unlatched, and left over night).

Update. Well after much discussion and investigation it would seem that my issue could have been caused by anything. A bump in the road, a glitch from any of the cars systems, a breakdown of one of the thousands of electrical components in the vehicle even an outside source. A nearby power source, overhead cables, radio transmissions or someone locking a vehicle by remote key fob near my vehicle. Radio wave transmissions can interfer with the locking key fob signal and "corrupt" or not shutdown the systems correctly. Hence why some vehicles never go to "sleep" whilst parked in airport car parks or near frequent radio transmission areas like a ferry port or harbour. So, the SDD was hooked up and a complete vehicle fault code list was extracted, nothing too much was found, the two main codes were U1A03-55 and U1A03-62. Configuration Parameters. So these were cleared and the vehicle was given a full reboot and software update. At first it did not work, then it did then it didn't. So hooked up again and carried out the reboot and upgrade once more. Result, all working again as it should be. Phew. So a few more jobs to do over the next month or so prior to disposal.

I have the same symptoms with my 2007 tdv8. Would You please tell me how to do a reboot/update of the system.
Have just bought me a Gap iidtool.
Do I need to download new config files, and if, from where?
Would be most thankfull if You could take Your time to give me som tips.

My reconfiguration was done by a specialist with Land Rover equipment. As you have a Gap iid tool speak direct to them ( search the forum or look at your iid instructions).

I believe that if you provide them with your chassis number they will send you a link to upload your CCFs to your iid tool to then configure your FF.

One point, I am sure you can save your settings (CCFs) to your iid tool for future use.

If I am wrong in any way I am sure someone will correct me.

Good luck

Tanx🙂👍
