Stock radio/electrical problem???

[asian195]

Ive got a 03 F350 with the stock 6 disc in dash cd changer. The problem is everytime i turn the key on or turn the radio off and then back on, the volume automatically starts getting louder all the way to max. Also my backup sensors dont work, the light on the over ride switch is always lit. the sensors stopped working about a yr ago and the radio was about a month ago. Is there a underlying electrical problem i have?

Did you ever figure out a remedy for this problem?
My '03 Excursion 6.0 just started having a similar problem yesterday. However, my volume randomly turns itself all the way down.
Any help/advice would be great!
