Linking an i pod to a Sony CDX-MP40 using the bus input terminal

My CDX-MP40 doesn't recognise when I plug my I pod into the head unit using the BUS input terminals. Do I need to use the BUS control terminal as well? If so, is there any way round this problem. Many thanks for showing an interest Louis

Some Sony head units let you use the Bus audio inputs as an auxiliary source input, but yours is not among them. To play your iPod through the head unit, you'll either need an iPod interface module: or an auxiliary input module: The iPod interface will allow you to control and display the iPod directly through the head unit, while an auxiliary input adapter will allow the iPod to play through the head unit using the iPod's controls and display.

Another simple solution is to order the PAC Sony Unilink adapter from for $30. It makes the deck think there is a CD changer attached to the RCA connectors in back of the deck. This makes the RCA jacks selectable as an additional source. You then leave a Y cable connected to the RCA inputs in back of the deck and connect a portable music source and select it from the menu on the deck or via the marine remotes in boat applications.

You need to provide Clock n Data signal to activate Bus Audio Source. Actually this Bus Control Socket is to attach Multi Disc Player of Sony. Here is 2 pictures attached of bus related area for info. I am sorry, its difficult to hear MP3 sound at Bus Audio input in this model. Have nice day.

There is a auxiliary button on the sony cdx-m8800. Is there a way to hook up an IPOD? The stereo also has MP3 written on the inside face. Thanks

Contrary to the below Expert's testimony, the UK CDX-M880 has a REAR AUX connector that will enable you to play your iPod through your car's stereo.

You will not be able to control the ipod's interface through the radio. You will have to use the control on the iPod .

You require a Male 3.5mm extension cable like the following...

Sony cdx mp40 bus audio in

ok dont know if you will check up on this but fm transmitters are all garbage. for true undistorted sound go to an electronics store and ask for a rca to headphone cable. then just hook it up to the rca input and run the cable out of either the unit or somewhere on the dash. this will alow for a true connection and if you buy a brand name cable i.e. monster, radioshack, sony etc. should sound amazing. always happy to help.

Cannot play my portable audio device with Sony cdx c500x

It will only accept audio from the bus in conections when a multi changer is connected and selected.

This is how I connect my mp3 player to my sony.

Swap multichanger audio outputs at the rear of the stereo for my mp3 player, press source to select multichanger.

Remember as I said, if there is not a control cable connected to your multichanger it wont wotk!

Having problems hooking up an ipod.

The "bus audio input" works as an auxiliary input on some Sony decks, but not all. For the others, you need an auxiliary input adapter like this one: You can also use a Sony iPod adapter that will charge the iPod and let you control it through the head unit controls:

Audio in

Unfortunately, the "Bus audio in" jacks are only for use with Sony add-on components, like Sony CD changers. Without a Sony component connected to the Bus control jack, the audio input can't be selected. To add an auxiliary input to this head unit, you need to purchase an adapter:

MD/CD Changer Control Options

press source button repeatedly to select "CD" or "MD" be aware that in order to connecting Ipod to a car stereo you will need to use an extension cable with 3.5 mm stereo connectors on each end to connect iPod to your car stereo system's aux input, or use a cassette adapter if your car stereo doesn't have a sound input jack. Either of these items can be purchased at stores that sell car stereo accessories. good luck!
