Sorry to disappoint you, but I have never seen or heard of a 1/2 DIN tape Deck, in fact the only thing I have seen that was 1/2 DIN was an equalizer. But good luck to you anyway, I hope you find something that will work.

Just a random suggestion, since it is something you will only use occasionally have you thought of just using a walkman, or something similar with a earphone to rca converter and just hooking it up to your aux inputs
