Do the stock radios that are used for the Ford F150's require a code to activate? I ask because I purchased a 6 CD/MP3/AM/FM Audiophile radio about a month ago off of a salvage yard ad on EBAY. The radio worked from the get go, meaning that I mearly installed it in my dash, and it powered up and worked. I did not need a "radio code".
This morning, I started the truck up, hit the power button, and I have no audio output. The display shows the time, the radio station, the volume display, etc. It does not however have any audio. Worked fine last night. I plan to remove it's fuse to try a "power reset", although I think I'm wasting time.
Anyhow, do these radios ever require a code if they loose power? I would have thought it would have prompted me for one when I initially installed it.
I'm puzzeled as to why the audio just up and quit on me.
