Funny you said that. Back when CD players were mainstream and casette players were on their way out, I lamented that I preferred the casette player because I could use an adapter that could connect to various music playing devices, including ipods, phones, etc. If the car didn't have a 3.5mm AUX input, I was forced to use my CDs.
Grats on the 3!
Thanks, but I'm still waiting for my VIN.
