I just got a yamaha RX-V3900 reciever. I also have an Iphone 3GS (A2DP bluetooth stereo capable). I would like to play my iphone over the stereo. The issue is that the Yamaha has one dock input so I have to choose to install either a bluetooth adaptor (YBA-10) OR a ipod dock (YDS-11SL). I am looking for advice on:

1) Is the yamaha Ipod dock compatible with the iphone 3GS (this info is NOT on yamahas website)
2) IF 1) is yes, then what is a better choice, the dock or the bluetooth adaptor?

I know a couple of things a) the dock (if compatible) will recharge the phone, and allow the stereo remote to control the iphone. b) the bluetooth adaptor will allow playing music over the stereo while I have the phone with me in another room in the house.

Im not sure which way to go on this. Is there such a thing as a dock input splitter which would allow the attachment of both devices?

I'd recommend going the dock version (presuming it works with the GS). The bluetooth might be nice in that you wont need to place your Iphone in the dock, however audio distance can be incredibly limiting...the most I've gotten on any device running A2DP is about 9ft within the same room, so its great for wireless headphones and small scale data transfers, but probably not worth the headache and hassle of pairing and having to staying in close proximity.

Then again, if you put a 3900 on your home network, and link it with compatible home computers with all your (DRM Free) music then you have no need for plugging in the Ipod.

There are a few other unique features that may work better for you if you're the only one with the apple device to plug in (ie like just plugging in a standard USB thumbdrive or external NAS with all your music into the Receiver).

I'm not familiar with the term "DRM Free"

'DRM' is Digital Rights Management, ie Digital copy protection. Technically you are not allowed to save and then copy or move these files around, and DRM (theorhetically) limits what you can or can not do with specific file.

Since you're looking at an apple Iphone GS as the source you are probably familar with AAC.

Copied from itunes website

"iTunes music. Now 100% iTunes Plus.
Now, every song available on the iTunes Store is an iTunes Plus song. That means you get high-quality music with 256-Kbps AAC encoding, making every song you download virtually indistinguishable from the original recording. iTunes Plus songs are all free of burn limits and digital rights management (DRM). So the music you buy will play on iPod, Apple TV, all Mac and Windows computers, and many other digital music players. It’s also easy to upgrade songs you previously purchased from iTunes to iTunes Plus. You don’t have to buy the song or album again. Just pay the 30¢ per song upgrade price. (Music video upgrades are 60¢ and entire albums can be upgraded for 30 percent of the album price.)
"

Hope that helps.

One Caveat however is not all 'devices' will play back itunes songs (without being converted to a Windows Media Player (WMA) format)...so you may want to double check the manual if you have a large itunes AAC library as it may not work with streaming devices unless you alter the files.

Response from Yamaha:

"The YDS-11 is not officially supported because you have to put the phone in airplane mode to make it work."

They did not answer my question as to whether the cradle will recharge the phone.

It should, since they didn't change the pin configuration again this time.

Here's my advice. get an AppleTV. connect it to your Yamaha, use your iPhone as a remote control using the "Remote" app. Done!
