On earlier post I asked for help on D3 I installed on F350..Thought I had it done, but come to find out the problem came back..When I turn the ignition key to off, my preset stations begin to change, until i touch the screen..My factory radio would stay on for several minutes`until i open a door..D3 only does it when i have radio on, not with ipod...I have the steering wheel interface PAC swi-ps installed. Red wire spliced onto 12v Acc, not at the harness..Should it be?..Any help would be appreciated

Yes the swips needs to be powered from the radio harness. Otherwise you end up with the problem you're having.

Thanks cntrylvr, appreciate your help...will work on it tomorrow
