Could anyone please tell me how I can tell if my sound system is fibre or not?

I’m trying to source a stalk adapter interface for my freelander 08 to update the head unit and I’ve been told my original stereo system might be fibre optic so I would need a more expensive interface adapter,
is there a way I can tell if mine is fibre optic or not?
I own a 08 freelander td4 SE HSE spec
(Sorry I’m new so don’t know if I’ve posted correctly)
Many thanks Lee :)
 
The ICE coms bus is called MOST. It's used where you have the factory sat nav screen. The wheel controls are a simple resistive ladder iirc. If you have the screen, the wheel switches will be the least of the problems to overcome.

Sorry I’ve tried to reply to this twice and it hasn’t posted for some reason
Yes I have the screen and I wanted to fit the Kenwood DMX7017DABS with Apple carplay but have been told by Halfords that I could damage the icu unit on the car?
Thanks for your reply

It is technically possible to replace the HU, but there's going to be some incompatibilities with the factory equipment. This makes the installation far from simple and potentially very expensive.
 
Well I wasn’t bothered about been able to use the steering controls or even the on board sat nav screen, I just wanted the Apple carplay unit to work ok without damaging my car and the cheapest method possible?
Thanks for your advice i really appreciate it
 
There is a factory Apple connection thing, but not car play, not that I know what that is. It must be special to want to replace the factory screen though. The wheel controls is the easy bit. Integration with the amplifiers and other driver aids, not so simple.
 
The problem with pretty much any vehicle after about 2005 is the level of electronic integration. Even something like a stereo system will have a CAN data bus and many have a MOST bus too, like higher spec LRs. These data busses allow communication with other computers in the vehicle. So things like the reverse sensors work through the stereo speakers and the volume can change as road speeds alter. Even the clock on the dash gets it's time information from the stereo. So removing the stereo you'd loose the reverse sensors and clock straight away.
This doesn't include the MOST connection to the screen and amplifiers. This is a dedicated audio/ visual fiber connection. It links the stereo to the screen, CD multi-changer and amplifiers. Loose this and the sound from the speakers stops and the screen blanks out.
So with this level of integration, you need a technical whizz kit and quite a large wallet to replace the factory unit.

I looked into this when I had my D3. I decided to add a simple Bluetooth module for music from my phone, rather than loose all the factory integrated stuff. The D3 shows all the Terrain Response infomation on the screen, and I wasn't prepared to loose that for a more modern stereo.

Thanks Nodge68 I understand more of what you mean now, see I was under the impression (because of the advice I received from Halfords) that I could just buy some leads and swap these straight over as I told them I never used the screen because I thought it was only useful to me for the sat nav and my iPhone was more accurate anyway. Is the screen used for diagnostics for repairs etc?

Thanks for the help

No diagnostics on the screen, but there will be vehicle settings and stuff.

If the nav isn't as good as the I phone's pretty poor navigation, then get the up to date maps disc.

Fitting a replacement stereo is much more complex than just a few leads. You'll need to convert all the CAN and MOST bus signals into something that is still functional.
The CAN bus carries clock data and reversing sensor activation, setings information and potentially reverse camera images too, if so equipped.
The MOST bus carries the nav information, CD music and amplifier music signals too.
So unless all those criteria are met, the system will fail to work. You'll not even get any sound unless you have a way to bypass the amplifiers. Obviously bypassing those will have a huge detriment on sound quality.

More investigation into the pro's and con's is needed before a decision is made.
