I’ve put together a web page about how to connect an iPod to a Sony car stereo. I had bought a Sony head unit in 1998 with cassette and a CD changer in the trunk. I had been using a cassette adapter but had some problems. So I wound up getting a Sony XA-300 auxilliary input adapter. This is a successor to the XA-107. The web page has other work-arounds that might be useful and it seemed more appropriate for that information to appear on its own web page instead of a blog entry.
