Connecting Bluetooth to OnStar

TheWeez · 04-09-2009, 3:29 PM

Since the OnStar in our vehicles is worthless now I'm thinking of making some use of it. Looking to hook a Bluetooth headset up to the speaker and mic. When a call would come in you could simply hit the OnStar button to answer it.

Anyone have wiring diagrams for the OnStar system or buttons?

Alright guys I might have an answer for you.

I currently have a Bluestar.Details here http://www.costartech.com/

It is fully functional in my RL. Uses the onstar buttons to control a Motorola bluetooth car kit.

I personally love the product and am glad I have it. Here is the deal with it though. Our cars (2002-04 RL and 2003 CL/TL) all use a Class 2 type onstar system.(non upgradable) This company makes a kit for the Class 2 Onstar units, BUT its not completely the same since our cars do not use the Class 2 interface to the rest of the vehicle. So a special unit with a different program is needed.

I worked hard with Chris from Costartech for over a month checking wiring and troubleshooting on my RL. We finally figured everything out and got it working flawlessly. Since the one in my RL was a custom one off that he was willing to take on its not a product he intends to make as he didnt even know Acuras came with Onstar. So I told him there is a market for it among the Acura owners. Iwas informed if I got at least 10 buyers he would make them.

I posted this info over on Acura-legend.com but didnt get to post up any pictures vids etc. http://www.acura-legend.com/vbulleti...uestar-136855/

This isnt exactly pug and play though. There are 11 wires that you need to disconnect from the Onstar and connect to the Bluestar. I took alot of pictures on my RL and can make a how to if this small production run would get off running.

The units run about 260 shipped I think. I dont know if there would be a discount for the group buy.

Look around the costartech website for specific details and if there seems to be interest I will make some vids and post pictures of the process.

I have the wiring diagrams for the RL, Cl, and TL Onstar systems and the wiring is almost exactly the same.

I have been busy with my family and havent been able to put up a decent post with more info etc but again if there is interest i will put it all together somewhere.

This is working on the RL and CL/TL should be the same no probs. If we can get 10 people with either 2002-04 RL and 2003 CL/TL than the product would get made. i havent posted this anywhere other than acura-legend.com. so if the word gets out and theres interest who knows. I'll wait for the replies to see.

OLD_HATCH · 04-15-2009, 10:34 PM

Would anyone be interested in this?

Would it be better to post something like this in a different forum?

**Ken1997TL** · 04-15-2009, 10:37 PM

I'm interested.. 2002 RL here

you should post this in the 1st gen RL and 2nd gen TL forum too

OLD_HATCH · 04-16-2009, 6:37 AM

Ok.

Let me get my pictures together and small video with wiring diagrams and I'll post up a thread in all sections that this would benefit??? (02-04RL and 03/CL/TL)

OLD_HATCH · 06-02-2009, 12:11 AM

For anyone interested a company called CoStartech is making modules that replace the OnStar units with a product called the "BlueStar"

The BlueStar is a bluetooth handsfree kit that uses the Onstar buttons, microphone, and mutes radio audio when calls are placed or received. Its composed of a Motorola HF850 module and BlueStar module.

Now here is the deal. This company is not making any units for any Acuras at all. When I contacted the company I notified them that some Acura models did in fact come with OnStar and they worked with me on getting a working unit.

They had to work with me because GM OnStar unit uses a "Class 2" interface to comunicate with the GM vehicle electronics. Now Acuras dont unse a "Class 2" interface so a custom product is on order.

Costartech made a "one off unit" which is currently installed and working beautifully in my 1st gen RL with OnStar (2002-2004). Here are some quick vids. Excuse the quality as they are only from a P&S camera.

As you can see from the vids it works just as it should. The microphone is far better than any aftermarket solution I have tried. Sound quality is better and the other party can hear me well. There are more details of the BlueStar along with directions here:

http://costartech.com/pb/products/bluestar.html

Basicly the Blue onstar button becomes the usual Bluetooth hang up/pick up button. The red button becomes the mute button and the circle button when used with phones that support voice dial over bluetooth initiates your phones voice dial prompt.

If you can install a radio or follow simple wiring diagrams then you can install this unit.

I have looked over the wiring diagrams and this unit will work on all 2002-2004 Acura RL's and should also work on 2003 Acura CL's and TL's that came equipped with onstar. There is a slight difference in pinouts on the CL/TL units is all. (mic leads and ground)

If there are people interested please post here:

http://apps.costartech.com/Forum/mes...start=0&last=0

I will not be handling any money and am just giving back to the Acura comunity with this information. I was informed by Chris at Costartech that if he saw enough interest then he would make a small production run or even keep them in stock.

Here is what everyone probably wants to know....price. Well the units cost 260 shipped. This is what I paid. I do not know if there might be better pricing since there needs to be interest first.

Mods if you could sticky or move this info to where it needs to be than feel free.

Remeber if your genuinely interested please post over in the Costartech's forum link I posted as well as contacting the company itself etc.

OLD_HATCH · 06-02-2009, 12:38 AM

Heres a quick tutorial of sorts.

You need to locate the Onstar Module which on the Rl's is located on the Pass side behind the rear seat. (rear seat must be removed) On the CL/TL the unit appears to be on the Drivers side behind the rear seat.

The biggest gold looking unit with the two plugs(red/blue) is the Onstar unit.

You do not need to unplug the red and blue plugs if your good with wires (and lazy

) but taking them off makes things so much easier. You first need to take off the plastic wire gurads clipped on top of the plugs. In this picture it shows on and all you have to do is pry back the two little prongs pointed at by the arrows.

and then remove(pull back) the wire guards.

After both the wire guards are removed you can then pry out the plugs.

After that its just a matter of cutting some of the wires going into the Onstar and rerouting them to the BlueStar's 20 pin plug. Looks like this.

Here are the back of both the blue and red onstar plugs along with the BlueStars plugs numbered by pins.

The pinout for the BlueStar plug to the varying connections on the 2002-2004 RL are as follows.

Now for the CL/TL it will be a little different as the mic leads are switched and the ground needs to be moved.

For those interested here are the pinouts for the RL's Onstar unit:

And here is the pinouts for the 2003 CL/TL Onstar units:

OLD_HATCH · 06-02-2009, 9:34 AM

I think after looking at the website again it was prob a little cheaper. either 240 or 250 including USPS priority shipping if I remeber correctly.

The price is a little steep as far as bluetooth car kits go, BUT it kicks bluetooth carkits butts.

I myself have tried a couple of Scoche units along with the Alpine bluetooth module connected to an Alpine IVA-W200 multimedia system.

This works as it should and is on par with factory installed bluetooth handsfree kits.

Unfortunately It isnt as simple as say tapping into some wires and hooking them up to your aftermarket bluetooth kit. The buttons on the Onstar comunicate in a special manner and isnt as simple as say a ground or positive pulse.

Pricey yes, but if you want an almost stock solution as far as bluetooth handsfree solution goes with same quality then this is something you might want to consider.

OLD_HATCH · 08-05-2009, 4:21 PM

Oh forgot about this thread. lol

Well I have switched phones to a new Palm Pre when it came out and so far everything is still good.

trini-34 what information do you need other than whats posted? I think thats a pretty good tutorial for anyone interested, but if you have specific questions I will be more than happy to answer them.

Ken

What kind of phone do you have? The kit is pricey but I have enjoyed it much in the past couple of months. road noise is not usually a problem either unless its thunderstorming hard and your driving fast. lol

for me its worth the money as far as safety and tickets. If you have any questions let me know.

**Ken1997TL** · 08-05-2009, 4:24 PM

I have a Palm Pre as well

DStetter · 10-05-2009, 9:44 PM

OLD_HATCH, I tried the pinout you suggested but I think the mute pin on my 2003 TL with NAV is not PIN 10 on the Blue connector or the Costar unit I have is expecting that ground activates mute. Currently with ping 10 cut the NAV system audio is not working properly and I need to reconnect the wire to see if this is the issue.

Are you sure about PIN 10 being mute on the 2003 TL?

Thanks for any help.

OLD_HATCH · 10-06-2009, 11:58 AM

PM/email sent.

**Ken1997TL** · 10-15-2009, 4:23 PM

Well I ordered mine today, I'm grateful for these instructions

Thanks Old_hatch

OLD_HATCH · 10-22-2009, 7:30 PM

After trying to help another member getting this installed into his 03 TL I have made a pinout sheet for the 03 Acura CL TL to replace the Onstar with bluetooth unit.

If anyone with a 2003 Acura TL or CL would like to verify my wire colors for the OnStar plugs I would appreciate it.

Oh and in case anyone is wondering. I am NOT affiliated with the company that makes the Bluestar. They were simply kind enough to work with me to get this working in my RL so I figured since I did all this wiring research I would pass on the info for anyone else who might be interested.

We really appreciate Your efforts Hatch. Quit a contribution to the site.

**Ken1997TL** · 10-30-2009, 12:34 AM

I received mine today and the newest batch is Revision B1 with different wiring.

For now, in case anyone is interested, here is what I've figured out from fiddling around with it and the wiring diagrams. I'm installing it Saturday so I'll redo the instructions if needed.

There are now TWO harnesses, not one in this newest edition. Also, the bottom of the circuit board has a purple wire, thats for the mute function.

Here is a guide of which wires come from which harness:

Harness One:

Pin 2 = Red = Red LED
Pin 3 = Green = Green LED
Pin 6 = Yellow = Mirror Power
Pin 8 = Black = Ground
Pin 11= Grey = Keypad Power
Pin 16 = Red = Battery

Harness 2

Pin 1 = Out+ = Yellow
Pin 2 = Out- = Grey
Pin 5 = Data = Purple
Pin 9 = Mic+ = Purple
Pin 10 = Mic- = Black

Circuit Board has a purple wire as well, thats the mute wire.

OLD_HATCH · 11-01-2009, 9:36 AM

I will see if I can make updated pinout sheets.

the data cable will not be used on our cars and the power will be connected to accesory power on these newer 2 pin units.

**Ken1997TL** · 11-03-2009, 5:51 PM

That would be great. I didn't get it to work quite right over the weekend.

I'm going to give it another shot in a few days, just been too busy..

OLD_HATCH · 11-04-2009, 8:11 PM

I'll try n get some new pinout sheets in a day or two.

Feel free to get in contact with me.

OLD_HATCH · 11-15-2009, 10:10 PM

If someone could please edit my post (# 7 in this thread)

If after the sentence, "The pinout for the BlueStar plug to the varying connections on the 2002-2004 RL are as follows."

You could add these 2 pictures:

And after this sentence,"Now for the CL/TL it will be a little different as the mic leads are switched and the ground needs to be moved."

Please replace the picture that is there and put these two pictures:
