Hello,

I have an Opel Corsa from 2007 with an original CD player with MP3 and I use a Parrot CK3100 for hands free talking which I believe is connected to the Aux Line In in the back of the car-stereo.

I would like to connect an external mp3 player (such as an iPod or my nokia N95) to the car-stereo but since the aux line-in is already being used for the parrot I would like to know if there is a solution to integrate the 2 devices (parrot and iPod). Even if only one works at a time. Is this possible at all?

I assume there is only one line-in in each car-stereo, right?

Thank you for your help.

Hands-free line in is likely to be mono.
Here are some mods I made to a CAR300 headunit in a '97 Corsa for a stereo line-in: http://homepage.ntlworld.com/rob_wit....html#headunit

Thank you for your help.

Yes, but the car-stereo's line-in has stereo sound capability, right? What I want is to connect the iPod directly to the car-stereo's line-in but since it's already ocupied by the parrot I would need a device with 2 line-in and 1 line out and it should be able to tell which line-in is on and which is off. Is there such a device?


EDIT: By the way, the car-stereo is a CD30 MP3 but I'm not sure if it's built by Blaupunkt or by Delphi-Grundig.

new to this, but here's my recommendation:

I'd have to see a pic of the connection to see what type of connection your aux input uses, but you might be able to cut/wire a switch in to switch between various aux inputs. i'm about to do this to my old delco stereo with the cassette deck. i'll have it so i can flip a switch to choose between radio or cassette/aux inputs.

does that make sense or did i just mumble on about nothing?

DavidAzevedo

No, you make a lot of sence. Thanks.

What I need to know is what would you use to make that switch between both line-in.

U can probably get a 3PDT switch and a few 1/8" phono connectors or RCA jacks (depending on what type of connectors the stereo has). So you can switch your L, R, and ground from each source. I used to have this type of setup when I had 2 satellites portable satellites radios on my car.

Not an expert, but I have my car pc and my xm both going into my aux input (through an adapter) in a 2001 chevy.

Im not sure if you need one to "over ride" the other, like shutting the mp3 when the phone rings, but you do realize that you are probably controlling which input is amplified by the head unit yourself already when you hit the aux switch ?

Just posting because I often see people asking about running two (or more) things into one aux input and they seem to think that they have to shut one to use the other, which is not always the case.

The aux input doesnt care whats going in, it sends whatever (even two sources merged) to the amplifier. So if you wanted to run an mp3 into the same input as the parrot, all you would need is a simple splitter type connector. If it goes into the aux as an rca, just use a two into one rca, if its d sub mini (like a pair of headphones) just get a two into one of those at radio shack ($2).

Turn on the radio, hit aux, turn on the mp3 = music. The parrot is still going in, if the phone rings it will be amplified and come out over (combined with the) music, if thats not good for talking, reach over and shut the mp3 player and the parrot will work like it did before.

Just an idea.

Thank you for your replies.

Ok, it seems I can simply plug in both devices (parrot and ipod) at the same time into the aux input. Great!

Now the problem is that I have no idea where the wiring goes and I am afraid to ruin the existing parrot connection. I have never been one of those guys who like to gut devices open and see what it has inside. Is it easy?



By the way, what's an "xm"?

XM = Xenomorphic Matterantimatter flux capacitor.

Sorry, couldn't resist :-) (XM Radio)

XM = XM Radio, Sattelite Radio, like Sirius . . .

Small antenna (looks like a GPS antenna) tuned to receive sattelite based radio programming. Loads of stations, decent sound quality, never out range of a favorite station (you can get shadowed and not get a signal altogether, its rare but can happen, but if you get a signal you get your favorite station anywhere you go)

Go to any Best Buy or Circut City, you will se a big display.

That DPDT switch trick is pretty good, however it involves routing the wiring to an accessible place. A better method is to use a tiny 12v DPDT relay (mounted close to the audio), powered from a 12v supply by a SPST switch (and a small resistor, e.g. 10ohms).
