My goal is to only have one single cable to plug into my iphone when I get into my car with the following connections.

>on one end - 30pin to plug into the bottom of the iphone

>on the other end - USB to charge, and mini jack audio
(or RCA cables I can convert to mini jack)


If I buy one the AV cables will it disable the iphone screen while plugged in? I want it to not affect the iphone in any way, and just pass the audio/power.

more details:
I have a 2008 BMW 335i that supports the iphone.
(it has a short 30 pin cable that splits into usb/mini jack audio) in the center council flip up
I originally did this:

Two problems though.

1) when you plug into the BMW iphone cable, the iphone screen is disabled (accessory in use) and you can only control it through the Car's idrive screen which isnt great, and also doesn’t allow me to play non itunes audio!

2) the bmw cable is too short at only like 12 inches long. I want to place my phone into a dash car mount which means any cable needs to be at least 3 or 4 feet long

I want one single cable with a 30 pin connection on one side and usb + audio mini jack (or RCA cables I can convert to mini jack) on the other end.

Is it possible to find something that works?

even more details:
I had an idea to use a normal USB extension cable, and normal mini jack extension cable. I then split open the plastic shield of the USB cable and exposed 4 wires.
USB pinout and signals @ pinouts.ru
2 are data and 2 are power. I cut the data wires. (leaving USB 5 volt power only) Ok, so now this kind of works. I'm getting all iphone audio to my car, and the iphone shows it's charging, but for some reason the iphone wont actually charge!, even though it shows a charge signal! (so I've given up this method)

Anyone, anyone?

For example, would this cable work in my car for charge/audio?

(or will it disable my iphone screen?)


How about the Kensington Liquid Aux? Will this disable my screen once plugged in? (requiring the remote control it comes with)
LiquidAUX(TM) for iPhone and iPod

The Griffin AutoPilot seems to be a possible match.
Griffin Technology: AutoPilot

User reviews say it works with iPhone 3G.
Griffin AutoPilot Track Control and Car Charger for iPod - Apple Store (U.S.)

This might work, as long as the auto-power plug is short enough. My Center council doesn’t have a very high clearance to close on top. This center area has three plugs, usb, aux in, and auto-power. It's hard to say unless I can get the dimensions though. Anyone have one?

The dock would work, but I dont want to place my iphone into a dock. I use the ProClip currently.
