How can I play my ipod in my 2006 Nissan Altima?
I tried looking for interfaces (ipod adapters), but none are compatible with my factory radio since it does not have a SAT/CH/CAT button. What are my other options?
I would like to keep the factory radio intact. Also, it doesn’t have an Aux input or cassette player.
either a new radio or a fm modulator, but dont get a wireless fm modulator they are terrible make sure its a direct connect.
