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

    The ipod pug in doesnt recognize my ipod and it wont play

  • kiltsclogs May 30, 2008

    the sony xa-110-ip unit is NOT compatible with the sony cdx-mp40 headunit! once conected (more or less plug and play) it will display on the ipod the xplod logo and you are able to scroll thru lists and play songs on the head unit (the radio) and control the ipod from the head unit, however it will at random reset the units and it will start at the very first song on your ipod. not only wil it reset with ipod hooked up, but also the radio and cd function/part will reset (off/on) and is very frustrating. also it will not remember the last song it was playing. it is a real shame, it would have been an easy and cheap (usd40) solution.

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.

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...

Aux input for sony car stereo (cdx c 5000r)

For Sony Stereos, you will need to get what is called a Bus Converter. The RCA ports you are trying to use are for a CD changer or alternate device like satellite or HD radio, and those have to have some sort of frequency signal to even be selected. You can find a Bus Converter that will allow you to use this as an Auxiliary input. The device you are looking for is called a Sony XA 300, and it will allow you Two extra Aux Inputs, I believe.

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.

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!
