Sony Audio Casette Adaptor for Ipod!

This may have been mentioned before if so I apologize for the repeat. I was trying to figure out a way to connect my daughters ipod to the JBL radio in my 05 & I just remembered that I had an old Sony audio cassette adaptor CPA-11 that I got with a Walkman years ago. It's a side loader & worked perfect in the JBL casette player. I think this adaptor was replaced by the CPA 9 & is 11.95 at Amazon.com. There's another brand for 10.95 that you can front or side load. I basically leave the adaptor in the radio all the time. This seems to work a lot better than the FM transmitter that my son had plus its simple and cheap.
