Ive got 2003 Caravan with the stock radio(cd/tape). Im going to buy a 2007 but they only have cd. I would like to keep the tape deck, this is how I run my mp3 player through the van. Ive tried the fm transmitters but i travel great distances and constantly changing the station really anoyed me. I prefer the tape deck cause its hassel free.

Dose anyone know if I can swap these two radios without any modification to the van or the wiring?

 

It may work. The only you are going to find out is to plug it in and try it.
