Thank you I will check it out, I will keep you posted
Does the radio lose preset's and clock lose time when key is switched off?? P1000 code???
No Codes ,and its not the original radio anymore.
P1000 is Ford's code for monitors incomplete!! Have it scan tested with a professional scanner! Not just a code reader hooked up....Now does anything else lose memory when the key is switched off.??? Stereo, clock etc...?
