Recently bought a Ford Fiesta Zetec 2000 car , It's got a built in CD player but is there anyway I can listen to music from my iPhone through my CD player? I had one of those Belkin FM transmitters before and they're not that great. I've heard you can buy small cables or something to plug into your iPhone but I don't really know what I'm on about to be honest.
Probably the easiest way is to get a new head unit, shouldn't set you back too much, and can give you functionality such as music over bluetooth, proper ipod controls etc, just check before you buy.
I have one I'm looking to get rid of due to a change of cars, it has 3.5mm input which will plug straight into your iPhone's headphone jack and it also has USB for things like memory stick, you can't plug the iPhone into the USB port though.
You can get a little device which makes the iPod look like a CD Changer, means you keep your OEM stereo with all the functionality of the dash controls and stuff without massive pain in the ass of making it work with looms and harnesses and stuff.
Mine is made by Dension and I think they are around £50. You just pull out the stereo, plug it in the CD Changer input (if you have one) and away you go. And the dash controls work to control your iPod!
The other option is some Bluetooth car kits (not the things that go round your ear, the proper installed kits) have internal amps and bluetooth audio integration. I've got a Parrot mki9100 and that's got 3.5mm jack, iPod and USB inputs as well as Bluetooth. It's not bad, though it's not exactly audiophile quality or excessively loud (it starts clipping badly if you try and turn it up too much). It's also a good idea to start the music before you start moving, it can be a bit temperamental! (I think the firmware needs updating).
I'd go for an aux in cable for your current stereo to be honest. Pretty sure you can get them for most relatively new ford stereos and come resale time an OEM cable is more attractive than an aftermarket stereo (assuming of course it's a cheap halfords option).
You can buy on ebay small converters for £30 whcih you attach to the the radio on the back, then drill a small hole to thread the new aux wire through. I used this on my Clio couple of years a go. However its a hassle and although it worked great i'd advise just getting a new stereo. you can pick an aux one up on ebay for £40 easy
Get something like this. Any FM transmitter that says it will work with your phone should be fine.
I've had one and they're great. They plug into the bottom of your phone and use that power (generally).
You choose a frequency where you can't really pick up any other stations (scan stations, and where you find a big gap, choose one in the middle of the gap), and set the transmitter and radio to that station, and out comes your music. Wireless and easy.
