I've been running this setup I posted last year: just-bought-a-2006-m45-tech-package-mp3 ... ?hilit=aux
Basically, I was tired of having two cables (charger and aux) plugged into my phone and the mess it caused just to have music...
so I tried a cheap Bluetooth streaming idea that came to mind.
(Note: this only works if you have the rear aux inputs)

Total cost around $15

Parts:
*USB 12V Charger (http://www.ebay.com/itm/Mini-Bullet-Dua ... 53f4196aa8)
*USB Bluetooth Aux Receiver (http://www.ebay.com/itm/USB-Bluetooth-M ... 2c761ba37f)
*3.5mm to RCA cable (http://www.ebay.com/itm/3-5mm-AUX-audio ... 27a7e74165)
Image

Steps:
Pull the back panel off the center console
Unplug harness
Unscrew the 12V socket and Aux input panel
Plug all of the parts as shown in the image below
Plug the harness back together and test to see if you can pair your phone. (I found out that my fuse for the power had blown)
Once you hear the music, tuck the parts under the center console and Pop the cover back on.
Image

This took me less than 30 minutes and the audio sounds even better than using the cable.
There's audio coming through the bose surround speakers in the seats!

Just thought that I would share in case anyone wanted a cheap Bluetooth streaming solution.
Good luck!

so how does this work in conjunction with the OEM bluetooth? Meaning does it get muddy up once someone calls your cell phone?

Good solution and even better if it works flawlessly. :mike

I no longer use the factory Bluetooth since I can use this setup for phone calls and music.
I just leave the audio on AUX and do everything through my phone. You lose the convenience of having integrated dash/steering controls, but I rarely used those anyway.

After reading this, I thought for a second and realized that i never disconnected the car's Bluetooth. After work, I got in the car and the phone connected to both the car and Bluetooth receiver. I didnt think that it was possible to connect to two devices simultaneously. I started streaming some Pandora and then used the button on the steering wheel to make a call and sure enough, the music muted and the call went through. The music resumed after I ended the call.
A little more desirable again.

Please confirm that your phone reconnects to your "streaming Bluetooth" with no user interaction, just as it does to the "car Bluetooth" (i.e., car turns on, and the phone is connected).

Thanks for the information.

Yes. Everything connects automatically after being paired for the first time.

Kudos dude! Awesome functional experiment. I bought the bluetooth receiver just now and already have the rest. One thing more I would do is install an inline accessible fuse and tape the receiver to the socket just in case it jumps out from all the bad roads here.

Advice like this should be paid for :werd: Just sayin.

Thanks! This was the only feature that I felt was missing in this car. I sacrificed the rear inputs, but those were never being used anyway.
Whenever I have time, I'm going to clean up the install and ground everything to a common ground. There's a slight ground loop whine, barely noticeable in between songs, but I know it's there.

This solution should also work for anyone who's using the USA Spec iPod adapter, which also has RCA input as an option. I use my smartphone for Pandora, so this will be a huge benefit!

I also just found an app called AIR PLAYIT, which is supposed to let you access you music collection from home. I haven't set that up yet, so I can't say how well it works. But combine this app with the wireless bluetooth solution.......and no more iPod, and no more cables!

I also have a magnet on the back of my phone that allows me to stick my android phone right on the dash panel under the CD slot. So while I am driving I can see all my Pandora music and my entire home music library right on my dash. very cool!

Can you share the magnet solution?
I'm trying to figure out how and where to mount the phone

Just do a search on ebay for CELL MOUNT MAGNET.

The magnet that attaches to the back of your phone is almost paper thin. Just mount the other magnet to the flat space beneath the CD slot, and you have an instant (and nearly invisible) phone mount for the car.

I haven't gotten around to that yet, but when I do, I'll post when I have a working solution unless if someone else beats me to it.
I'm glad that this is useful to some out there!

Hey. I too had that dreadful noise. It's the cheap charger. I had one similar to yours and it made all sorts of funny noises. Then I switched to an authentic iPhone iPad 3 outlet unit and plugged it into the 1.2a USB plug. No more noise.

Thanks for posting your findings. The noise is so slight in my setup that I haven't felt the urgency to check it out yet. I'll give a new power adapter a try first to see if it totally eliminates the whine whenever I can get one.
I'm loving the setup so far!

Thanks for sharing this! My bluetooth dongle works perfectly... I was using my battery pack to power it until the mini bullet USB arrived. I also noticed mild noise but the little POS didn't last a day I think I used it twice and it died. So if anybody know of a better one please post a link. I would like one with no noise.

I basically have the same setup, but I added a Blackberry Bluetooth Gateway (really high quality sound), and a Ground Loop Isolator to remove distortion at high volumes. I just want to know how you were able to take apart the rear inputs. I tried pulling it out, but it seems like there might be screws attached or something; I would appreciate any help you can give me. As it stands now, I have the flap open to connect the wires.

Sure thing! I'll go out and take a few pictures of my setup and the parts tomorrow morning. I'm not sure how the OP's sounds, but after trying several bluetooth streaming devices, I'm very happy with the second generation Blackberry Music Gateway that I have. It is paired with both my HTC One and iPod Touch and I've never had to re-pair it, even after leaving the car unused for prolonged periods of time (1.5wk). I did run into an annoying hiss when I first installed it, which I came to the conclusion, was caused by the alternator grounding affecting the power socket. A ground loop isolator eliminated that issue completely. I'm able to have the music paused and turn up the volume all the way to the maximum without any discernible hissing noise. Like I said, I'll post pictures of my entire setup and all the parts tomorrow morning.

P.S. If anyone knows how to remove that back input flap like the OP did, please let me know. Thanks!

I decided to splurge a little bit due the cheap USB charger I bought from the OP link. I'll try it out and let you know how it works out for me. $21.06 shipped

Not difficult at all. You just pull on the entire back panel of the center console and it pops off.
You'll then see how it's screwed in from the inside. Good luck!

My $15 setup works/sounds great so far. This was originally supposed to be a cheap proof of concept prototype, but ended up worth keeping. Better parts will probably last longer. My phone automatically connects to both the car for phone and the receiver for music. Like I've mentioned before, I still have to isolate the ground loop, but it's so minimal that I only notice it when I listen it for it in between songs when there's no music playing. I'm glad that this is helping out so many people!

Donations are welcome ;)

Thanks for the suggestion. I got the phone mounted right under the CD slot and it's great to have the phone out of the way!

Thank you so much! That worked. Originally, I had to leave the flap open all the time to connect the wires to the input, but I managed to take apart that panel, take the connections out of it, and run them underneath that whole rear panel. I did have to remove one of the zip ties that was holding the wire to the right side of the console. The metal box underneath the console had warnings about airbags going off if struck, so I decided not to leave all the components inside (as clean as that would've been). Another reason not to leave the components underneath the console is for ease of access to the A/V input jack; in my ownership of the car so far, I've never used it, but who knows.

This is the wire that used to reach the flap and feed the A/V inputs, as well as the charging port. I ran both of those ports underneath the metal at the bottom (there's enough space) in order to not have the panel squeeze them when put back on.
Image

Here's an overlay of the entire setup (I originally had an audio cable extension from the Ground Loop Isolator to the car inputs, but I removed it when I ran those connectors under the panel.
Image

The Blackberry Music Gateway connects to the charging port (I had an old USB cellphone car charger lying around that I used) and included both 3.5mm and RCA audio outputs. Obviously, I'm using the RCA. Keep in mind that this is the second generation gateway, so if you do decide to get one, make sure it is the second generation (look for the NFC "tap to connect" at the top of the box), as I've heard about some bluetooth pairing issues with the first gen. Originally, I had the RCA audio cables connecting directly to the car's ports, but as I mentioned previously, there was a noticeable hiss/whine, which was really annoying, even at regular listening volumes. At loud volumes, it was not even worth using it. I had this issue with all powered bluetooth streaming devices I used (powerless is not an option, because I don't want to deal with replacing batteries), and after some research, I decided to try a Ground Loop Isolator.
Image
Image

Here's the Ground Loop Isolator (RCA audio input > RCA audio output). I purchased it from "The Source" (it replaced, and is equivalent to Radioshack). This thing is incredible! When I purchased it, I assumed it would alleviate the hissing issue, but it went far above my expectations and eliminated it entirely! If I pause my music and turn up the volume all the way, the only sound is normal minimal white noise. No hissing or other annoying sounds!
Image
Image

I could stand to make this a little cleaner, but I don't see much of a need as the carpet keeps everything in place, and I have the benefit of easy access to the Bluetooth Gateway (if I ever need to pair a new device) and the car's A/V inputs.
Image

The flap is now completely empty:
Image

Here's everything put back in place. I don't have to worry at all when I have someone in either of the back seats. I never carry 3 passengers in the back, but if I did, I'd probably have to be really careful.
Image

Cost:
$20 for the USB car charger. I'm not sure what prices are like for it now; I purchased it about 3 years ago and wasn't using it.
$60 Blackberry Music Gateway; definitely worth it, IMO. I've tried countless cheaper solutions, and none come close to the sound quality. Also, it doesn't exhibit any of the bluetooth pairing issues I've had with other units (namely, it doesn't forget paired devices, even if I haven't used the car/powered it on in a while - I've gone up to 1.5 weeks with no issues).
$20 Ground Loop Isolator; I was in a hurry to get this. I saw much cheaper (~$5) prices online (and even at other stores, which were sold out), but it was simply more convenient to have it right away. That hissing sound was really annoying.

As for phone handsfree, my phone is paired to the music gateway, as well as the car's built in bluetooth; music goes through the gateway, and calls go through the car automatically. When a call comes in, or if I dial a number, music is automatically paused, and resumes when the call has ended.

P.S. I've been looking into several methods of controlling music playback without using the phone/iPod itself. There are bluetooth steering wheel clips, for example. If anyone has any experience with those, do let us know if they're any good :)
