I have an 06 F150 that I replaced the radio because it didn't work with a 6 CD unit that I bought off Craigslist. The radio works fine. The issue that I have is when I turn the ign switch off the radio returns at a very low volume every time.

Can someone please advise how to set the unit so that when I restart the truck the volume is at the same level that it was when I turned the ign. off. My son has a 04 truck with like stereo except single disk and his returns to db level when he restarts his truck.

thanks

John
