Hi: I want to install Sirius XM Satellite radio in my DB9. I am told that you should use an FM Modulator wired in for the best reception. I've seen the Youtube video on how to remove the radio but it didn't show the back connections. I want to order the FM Modulator so I have it in hand to install after I take out the centre stack, rather than tear it apart and then order the FM Modulator. Does anyone know (or have a picture) of the antenna connection at the back of the radio? Is it a standard antenna plug or will I need an adapter? Any other tips? Thanks!:rolleyes:

It should be a standard antenna connection. If not, you will have to splice into it. Buy a trim tool kit to remove inner panels. You can buy them online for $15 or so. They will keep you from scratching. Take you time. If it doesn't fit, don't force it.

Thanks for the reply. I'm not sure that the plug is a standard antenna plug. I believe the wiring is fibre optic so the plug could be non-standard from what we in North America are used to. If the antenna wiring is fibre optic that would mean that you couldn't splice into it. That's why I'm looking for someone who's seen the wiring and can answer definitively. I'd rather avoid taking the centre stack apart to find out for myself and then leave it torn apart while I order parts and adapters or put it back together awaiting those parts and then dismantle a second time to install. I'm nervous enough at the thought of prying at those expensive parts once!

radio antennae are in trunk lid

I think it is all at the back of the car.

The radio receiver in an early DB9 is a separate module located in the truck, communicating to the head unit via the MOST network. The actual antennae (yes two) are located under the inside of the trunk lid under the carpeted cover. To install an in-line FM modulator you will need to insert that modulator in line with an actual antenna. Pop off the carpeted cover and will see there are the two antennae with euro style miniature BNC type connectors. You will need a convertor to a standard Motorola antenna plug common in the US. There looks to be a power source to the antennae too, so maybe you can splice off one of those if needed.

Since there are two antennae I presume the radio receiver module tries to optimize reception by selecting the best signal. So... perhaps if you connect the in-line FM modulator to just one of these antenna the radio receiver should see that strong signal for your AUX/SAT radio input, and see the other for regular radio.

Now of course you have to get the AUX cable to your in-line FM modulator thread into the main cabin...

Trunk lid antennae pic

Here is a pic of the trunk lid antenna. 2005 DB9 Coupe USA spec. (I am working on removing those awful Fed-mandated rear plate lights plastic lumps - installed a regularUK lights/trunk switch.)

I recently installed the Dension Gateway 500 model number GW51MO2. This gives an aux in.

I also added the now discontinued BTA1500 to give me Bluetooth also.

So far it's working pretty well. I have tried various FM modulators before in various cars and I couldn't get comfortable with the sound quality........
