Have been reading through all the search facility on aerial connections and am after some clarification if possible?

Mine is a ‘97 mid-facelift CDX with no phone setup.

I currently run an Alpine aftermarket HU but have never had good reception from the radio so i suspect I have a damaged lead behind the dash as this sounds quite common. The roof aerial is good as I swapped it from my Astra Van a few years ago when trying to look into it then.

I have no aerial lead at all on the drivers side a-pillar unlike most. I have a grey coax on the passenger side a-pillar with a push-to-lock connection. Is this simply a different design for the DIN connection as in I will be able to put one of the DIN - ISO connector is its place and run a fresh cable?

Reason is that i am adding an Alpine DAB unit and this has an in and out for standard aerial as well as the DAB, so I was thinking of running from the A-pillar to the unit and then from the unit to the radio, all with new cabling.

From the factory, ALL Omega aerial looms run down the righthand sill and up the C pillar. Without exception. Cars with phone capabilities and/or nav will have more wires... 2/3 signal ones and a power feed, but all follow the same route... 

[iansoutham]

I have had a look and I have lots of wires running along the drivers sill bit nothing like coax.

On the passenger side a-pilllar, I have a RAKU II - RAST II connection on the grey wire that is the same colour as the one on the roof aerial. The roof aerial lead seems to go out to a screw connection above the roof light and then promptly goes to the near side of the car as far as I can tell.

If this RAST connection is not aerial, what is it?

[Doctor Gollum]

Telephone prewiring...

Saloon radio aerial is in the rear screen...

[iansoutham]

Mine is estate

[iansoutham]

Basing it on your way, where would I find this connection for the aerial in the A-pillar as there is no coax down by the big multiplug on the drivers side

[Doctor Gollum]

Someone had messed around with the wiring then...

Should be a 4/5mm grey cable running between blue plugs with a redwhite iirc 0.5mm wire...

[iansoutham]

Sure you are not thinking of the facelift cars?

[Doctor Gollum]

My direct experience is with facelift, but mid facelift cars had similar specs... ie phone and nav options.

Certainly only variations are saloon/estate, no/phone pre wiring, no/nav. On spec, looms are same to C pillar...

Your car should be wired as per Haynes

Having read this thread I would concur with DG,

But it may have been possible if yours is a late PFL CDX. my thoughts are some CDX around this era had a Phillips HU and a Serperate Amp, the Amp and its Wiring was located on the left Passenger side, with the Amp location either in the Boot space or Under Dash, depending on whether Saloon or Estate (and I cant remember which way around now), so it would kind of make sense for this one off CDX Amp option to run the Aerial within the same area or location.

Comme ca - in the drivers footwell behind the kick panel :



The chunky grey wire is the radio aerial, the other two black coaxes are satnav and 'phone I believe. All on a 2001 saloon RHD elite.

Brilliant.

I have that grey connection with the RAST connection shown but it is on the left side of the car.

The box is the same and I have no other cables as the car has no telematics.

I will try and run a continuity from the roof aerial to that connection to confirm link.

Weird thing is that if I disconnect that RAST connection the radio does not really change but if disconnecting at the back of the car, it loses a bit of signal (gets a bit crackly)

[iansoutham]

Okay, managed to get the car into the workshop at work and have run a continuity line between the connection to the roof aerial at the back through to the connection in the passenger footwell and can confirm that an October 1997 mfl does have the aerial lead on the ns a-pillar. Continuity of 0.004.

That's a bit tenuous... Literally connected by one strand

The closer that number is to 1 the better... Alternatively, the nearer resistance is to zero

Sorry, I meant resistance is effectively zero.
