quick stereo cable question

[Chills]

I did a search on the subject and found a number of threads regarding iPods and our stereos but I'm a little confused. Could someone tell me my options as far as listening to my iPod on my stereo without using an infernal FM modulator?

2002 Boxster S with Bose system and 6 disc changer.

I saw the RennTech option and that's a bit over my head.

I read about a Becker cable and that sounds good but what is that and does it enable me to see the songs and stuff on the radio display?

I found this cable but I'm not sure what it does and if it's any good:

Thanks in advance guys. I hope this subject hasn't been beaten to death yet.
