    I was bored so i installed a A2DP driver for my Windows 7 64-bit box.

    (more specifically the Widcomm Bluetooth stack BTW for Windows Vista download here http://www.parrot.com/documents/en/support/btw6.0.1.5300.zip)

    Everything works flawlessly (with an odd side effects that when i turn on caps lock now it tells me in the bottom right of the screen but i don't really care), it installs in a second, and reboots. When it stats back up, i pair my iPhone 3GS with my computer, connects immediately with no issues, and when i open iPod where the volume usually is it now says my computers name, and when i press play it comes out of my computers system, with incredible quality and very little skips.

    Now this is all wonderful, but a little pointless seeing that all my music on my iPhone is on my iTunes and can just play it there.

    But i had a thought. i often plug my computer into my TV to watch movies, and sometimes play games on the big screen, and every single time i do everyone in the house yells at me to turn down the volume, but then i cant here what the tv is saying. and not to mention my sound card is **** and had a lot of feedback from the processor. what would be incredible, is if i can reverse the roles of the computer and phone, and use the computer as the a2dp transmitter, and my iPhone as a a2dp receiver, so i can use its headphone jack and basically create wireless headphones through it. this would be extremely convenient in many many situations, and i've searched high and low for any solutions and cant even find a mention on the wide internet. does anyone know how to do this? that would be greatly appreciated! :)

    It should be a pretty simple app to build, no? All you really have to do is transfer the Bluetooth drivers from snow leopard and put a interface on it... Or maybe it dosen't work like that at all I don't know, I don't know too much about these things

    If someone built one I could see them making a lot of money on it, and I don't see why apple wouldent let them submit it, and if they don't there's always cydia, and that might be better because then it could just be plugged into the already made Bluetooth stack much easier

    I'm looking for the same thing. I would like to use my old iPhones (3G and 3GS) as A2DP receivers. For example, I can keep my 3GS connected in my car and stream the music from the iPhone4 wirelessly via A2DP. I currently use a Bluetooth Recceiver (http://www.monoprice.com/products/product.asp?p_id=7364) that works okay, but you have to manually re-connect everytime and you cannot rename the device name (so with multiple receivers you can't differentiate them). I figure if it is an app, it can be customized to auto-connect and/or change the device name, etc.

    I've been looking for the exact same thing; nothing in the A2DP/bluetooth world that I have yet to find.. :(

    I do enjoy airfoil and wifi2hifi, maybe you can get a new ride with WiFi in the cockpit? :)

    Anyone else know of a solution to make the iOS devices an A2DP *reciever*?

    I was looking if this is possible, too, but I don't think it is. If you jailbreak, there is a BTStack, but I don't think it supports A2DP in any form (not even output). Even with BTStack in existence, and having some coding skills, I don't think this is a simple thing, so I don't see it happening.

    Same as Nish, I was trying to see if I could repurpose my old jailbroken iPhone (2G/original) as a bluetooth receiver for use in the car. Car connection kit options seem to be lousy (at least the ones that don't cost as much as a new head unit), and I'm eventually going to get a new head unit, but want something to hold me over in the meantime.

    For kalafalas you could do something other than Bluetooth, such as buy Airfoil ($25) and use Airfoil Speakers Touch ( https://rogueamoeba.com/airfoil/ios/ ) as a receiver. But for $25, you may want to consider getting a Bluetooth receiver or headphones instead.

    Download line in for mac.


    One cable from tv earphone jack to mac mini line in jack (not one with headphones picture). And the open line in program. Select default system input and output. And in system preferences under sound input is line in. And output is your bluetooth earpiece. Nowe you can listen to tv with a bluetooth earpiece. No iPhone needed. My Plantronics PLT_M50 works great. Probably have to have a2dp on bluetooth earpiece but this has it. Got it at costco for 30 bucks. You can use line in also instead of system preferences. Input default and and output bluetooth or dmzmusic. But its buggy and some times doesn't work. But leaving it on default for input and output works great. And then system preferences for changing output to bluetooth earpiece or dmzmusic.

    Or get this. Same setup as before. But instead plug this into a wall adapter (the little white square iPhone brick you charge your iPhone with works great). The open line in application and select default for input and output. Then in system preferences goto bluetooth and when dmzmusic shows up pair it. If it does't show up remove the little usb dongle and in the link below and plug it back in and it will show up. Then goto sound and select output as dmzmusic.

    The plug in normal headphones into dmzmusic and the sound outputs to the headphones. I sit on my bed now and use this. No need for new wireless headphones now.
