My daughter has just bought a 2002 147 with bose system and wants to know if anything can be done to make it ipod compatible,am sure in past have read about this topic but my memory fades me,am sure someone in this forum has dealt with this problem, i am not that technically minded so if someone can point me in the right direction,ie. parts needed. thanks
I've installed a Dension ipod connector in our 159, and very happy with it. It replaces the input for the CD changer, so to listen to your ipod you switch the stereo to 'cd changer' and control the music on the ipod/iphone.
Although the speaker system is Bose in your 147, I believe the head unit is by Blaupunkt. You can go here to check the compatibility with your specific head unit (http://www.dension.com/downloads/car-compatibility) - click the button "go to selector" and it'll guide you and show you the different head units. Having said that, I think the same Dension unit fits all the variants.
I bought mine from a local company: http://www.cushieaudio.com.au/vehicles/alfa-romeo.html?car_kit_features=777&manufacturer_alfa=590
The cheaper model is cable only - you plug in your ipod/iphone to listen to music.
The more expensive model includes bluetooth wireless and a hands-free microphone.
I wrote up a bit about installing it here: http://www.alfaclubvic.org.au/forum/index.php?topic=10181.0
