That would be frustrating for both parties.

I've made many a cable. I know how you feel. Good luck with that.

--- Its just a thought, not tryin to stir the pot or anything. ---

Not a bad idea, I have an ipod interface that goes in the CD changer slot and it works OK.

I do see two problems with this though..
1. Audio level at CD port is line level (like what comes out of IPOD earphone jack) The moto audio out is meant to drive an 8 ohm speaker directly, so it needs to be padded down.
2. I'm not sure if the CD changer communication bus (entertainment bus is different than class 2 bus) supports auto switching. Meaning that when a call comes in, you might have to hit the source button on the radio in order to hear any audio if you are not already in CD changer mode.

Maybe STS2003 can add more info regarding this idea.

Also, for others who have been PM'ing me, I do not have enough posts yet to reply. Please email me at info@costartech.com with any private questions or comments.

Thanks,

On my kit, the audio won't go through the loudspeaker. The manual said it was a line level output meant to interface with your radio. But I dunno if others are different? I mean with my kit, it lets me stream audio to it, but I can't use it because I don't have it hooked up to the radio. It also gives me a line in, to hook something else up. But, like I said, it was just food for thought I guess.. LOL

I guess what I was thinking was that the Bluetooth Stream would emulate the CD changer, so if a call came in, the radio would still switch. I dunno I think I am thinking too far into this.

98 SLS does not have data bus communication with the changer it communicates using entertainment serial data
However if your looking for a clean aux in sound they do make an aux in adapter which uses the changer wires for direct sound

If it will work in my 2003 Tahoe, I'm interested.

Thanks.

Me too. Continuing to monitor the thread. Do we know yet if it will work on an 03 Base DeVille?

Does anyone know where I can get the parts that RustyBlazerDude is talking about?

Stuff like the cable and board to connect the motorola unit to the onstar unit?

Any help would be great
P.S. I would have emailed Rustyblazerdude but I can't without first having 25 post's
Thanks Dennis

He is making them, waiting to be tested, then hopefully mass produced! :-d

Thanks for the info.

Ok fellas, After a long holiday weekend, I got my #$% together and have mailed out the first batch of evaluation units.

With this we hope to satisfy the Seville / Deville markets going back as far as '98.

All other models that have class2 data comm should work provided we get the correct interface cabling. This includes all GM vehicles, not just Cadillacs.

The next step is to create these interface cables for various GM vehicles. If anyone has a copy of the onstar interface schematics from their service manuals, please send me an email (no PM's please) and I will begin compiling / defining and creating interface cables for the various vehicles.

With positive feedback from the field, we can begin production orders for anyone else interested in these units.

Keep your eyes on this thread for additional status updates and field testing results.

Thanks again for all of your help and interest in this.

I intent to read STS's entire thread on this an I hope it has the interest that I have for it. All these options I would like to have for my 96 but if it's not possible please PM me and let me know what I can do before my 38 page journey. Thank you.

[CadillacSTS2003]

got mine today!
just gotta buy the Motorola kit and we shall test this puppy out!
expect more from me in about a week

initial impressions VERY PROFESSIONAL looking set up
looks like it came straight from a manufacturer not a guy working in his garage
truly A1 clean looking set up

[StuJac]

Is it being tested on an 03 base Deville? Or any of the same models so we'll know if works the same?
