Took me a while but it didn't work. Used the one off my media center(3 bars in mini 3.5 plug), some other bs one with 2 bars in the mini jack. Also in my truck i have an alpine DVD player so i have the ir receiver from first wenigwiser's first post, it also would not work. Tried using a cr-55 from my d3. I saw somewhere on here that someone has a sony wired remote working but maybe a sony ir receiver and a sony remote might work or even a pioneer remote. There has got to be a way to get a wireless remote to work on the f units. I must call Pioneer in the morning a curse them out!!!!!!!!!!!!!!
