New BMW Head Unit...

Hello all -

New to the forum although I have "reading" for months.

I would like to put a Sirius-capable head unit in my '02 330Ci (which has a Business CD / no changer / S/W Code of 40)

Will a new unit swap out easily? Wiring all the same, etc.?

What can I expect to pay for one?

(Don't wanna go the modulator or 3rd party hed unit route)

Thanks in advance.

Who knows where to buy one?

See my resonse to your questions below:

You will need a head unit with a software code of 50 or greater

Will a new unit swap out easily? Wiring all the same, etc.?
According to others you can remove the old head unit and plug in the new one, with the exception of the antenna. The new unit may have two inputs, and require a splitter. Everyone says to use the Terk antenna and that BMW's "adapter kit" is not needed. All you need is the new head unit, Sirius receiver, and the antenna (and maybe the splitter).

What can I expect to pay for one?
Here's the rub. I've been trying to buy one, and the parts guys won't sell one, either claiming it won't fit; or that they do not have the SW version greather than 50. If someone knows a dealer who can make it work, let me know too. I've been to four dealers.

Circle claimed it wouldn't work; the "wiring is incompatible".. I'll try Pacific.

Wiring / Antenna Connecctions...

I have read about the different antenna leads... the "pre" Sirius actually have two (one small, one large) - the Sirius-compatible have one - only the small. Trick is - you have to get an adapter that will connect the large lead to the small connector. The small lead doesn't get used.

I believe the dual antenna leads were part of BMWs "dual antenna technology". Supposedly - there are acually two antennas in the rear window of the car and the radio senses "which" is getting the stronger signal and switches to receive its signal.

Dunno if they abandoned that in the newer models or not - or use a different cable to provide it.

If this is the only wiring incompatibility the dealers are talking about - it should be a non-issue. I read a post "somewhere" saying to get the large lead connected to the small connector - you need two adapters - first a Motorola and then one for a Chrysler radio... think they picked it up at Circuit City.

My Ride: 2001 330ci
New BMW Head Unit

I just completed this mod. I have a 2001 330ci with the HK and replaced the head unit with one from a 2004 E46. The swap was a 4 on a scale of 1 to 10, not difficult at all. With that said, the hard part is the antenna connection. The old radio has two antenna connections, a large one and a small one. The new radio has one, it is a small one (female), and the larger (male) connector is the one that has to be used.

I went to of all places circuit city and their guy sold me two adapter cables. The first one converted the larger male conection to a motorola connection, then he had another converter that converted the motorola connection to what he called a VW/Chrysler connection, which fit the back of the new BMW radio perfectly.

While you have the radio out, I would add the aux input as well, I use the aux all the time for my Ipod. It is great, worth the price of the whole mod.

As for the sirius, I put that in today. I have the 6 disc changer in the trunk. Mounting the sirius is a snap, you just screw it into the mounting tray and then one bolt holds that into the mounting rack, the same rack that holds the CD changer. You unplug the two cables going into the CD changer and plug them into the sirius, and then use the CD extention cord that you buy from BMW if you have the CD changer and plug that into the sirius and then into the CD changer.

The sirius antenna is a bit tricky. Getting that cord under the window trim is a job. I think you would be just as good putting it on the trunk. The antenna comes with something called a ADC box. You plug both the antenna connections into the ADC box and then plug the ADC box into the receiver. I don't know what that box does but my radio works better without it than with it. Activation was a snap, and when I called Sirius for activation they said BMW was paying the activation fee and the first two months of service.

Good luck with your install.

Where did you get the 2004 headunit and how much did you pay? Since I have a 2002 325ci (built in 11/01), I probably need a new headunit.
