Rob (gooner1) found a link to a site that gave instructions for adding an iPod input to an old radio cassette. Just did a quick search and couldn't find it, but will have another look for you.
It is dependent on you being good at soldering / fearless in the face of pcbs, however
My thoughts about this were to fit a mini Jack socket into a blank on the run of three switch positions (where the hazards, rear de-mist etc) are, so that when you're not using your iPod, you're just left with a neat little socket that doesn't detract from any oem homo aesthetic
No, I didn't, Mike, but my other half is hopefully collecting my old oem radio for me tomorrow (it's hundreds of miles away from where I am) and I have a spare switch blank in 'stores'.
If the plan comes together I'll do a write up / pictures / report back to you
As far as I know, radios are internationally interchangeable. I think you're getting mixed up with the PAL / NTSC division you get with video products.
Does that one have an auxilliary input? My German doesn't get me much further than ordering beer!
