Hi guys,

Sorry if this has been raised befor but I cant find much. I want to know the basic principle of the complete ICE system on my Vel Satis (but I assume it will be similar on all renaults with the full system).

My problem is that there is either interference with the radio reception from within the system or the aerial/booter/wire is shot and needs replacing.

Anyway on removal of the Cabasse 6 disc cd player I found no aerial lead/socket, on removal of the gps keyboard unit it seems the aerial lead plugs in here (with the newer type connection) so the satnav can pick up the traffic info. I assume an fm feed is then linked upto the cd/radio unit as there is another aerial lead with the older type socket next to it which when i pull out the radio loose reception. What is strange is that when i hold the plug with my fingers the reception returns and is much better.

Anyway the looms from all 3 units go off into the depths of the dashboard and dont seem to be directly linked to each other as when you give a light tug say on the cd rom loom, you would expect to feel a pull on one of the looms going into the back of the keyboard unit. The units are also quite close so you would expect a direct link.

Anyway if anyone could explain what unit actually does what this would be good, i mean is the fm reciever actually in the Cabasse cd changer part or is it in the GPS keyboard part?

There is another smallet RF lead which plugs into the CD rom unit, whats this? The gps antena i suppose??

Very complex, also which part connects to the screen????

Hi guys,

snip...

Actually quite simple.

The radio aerial lead first goes to the GPS dash unit to pick up the TMC signals.

A lead (sometimes missing) then goes from an output on the GPS unit to take the RF to the radio.

The RF lead going to the GPS CD unit is (as you say) the GPS aerial signal.

I modified the FM aerial signal on my Lagina with a splitter.
The pass through on the original design gives a 3dB signal reduction.

Ok if i wasnt interested in the TMC (i dont even know what its for) then cant i simply somehow join the FM input and output leads together to bypass the satnav control unit all together?? Is that what you mean?
