I just added a new Mufflex and disconneced the battery, like always when adding anything new. When I started the truck back up, my 8.4A display says "radio locked, please start vehicle". It rand for a couple minutes but still nothing. Any ideas anyone?? 
Well, could not get it back on last night, but this morning when I was leaving for work, radio came on and display was normal, all functions good.
