i'm not sure what you mean, the factory headunit was working until the power to it was lost and it started to show CDE on the display.

quick note, disconnect your battery whilst doing this if you havent already done so, my first ever installation i spent hours going over all my wiring trying to figure out why it wouldnt work, only to discover i'd blown about 4 fuses, most likely at the start of the instalation when i was messing around with the power wire.. haha...
