Thanks for your patience. Sorry but I am confused as to what to do next.
Here's where it stands:
I have made no changes to the modifications I made when I installed the Mediabridge, they are still in place. I have nothing from factory equipment connected to the Seicane harness in the photo. I do not have a blue wire connected to a white wire suggested in the video.
I have tried the blue to white wire, though I am not sure I have the right blue or white wire since that is not clear in the video. I have tried connecting the nav unit to the Seicane connector in the picture. I haven't tried both connecting the nav unit and blue to white wire at the same time.
At this point I have no sound at anytime. Same thing happened yesterday but it came back to the 20-30 second sound in the afternoon but is now gone again. I would like to get back to the 20-30 seconds of sound starting point before doing anything further. I'm going to check every wire now connected to Seicane unit and make sure a wire is not disconnected. I guess I could have changed something when I was messing with the Seicane unit trying to find the DSP coding but I have no idea what that could be.
I haven't verified the wires I put back in the blue connector are in the correct slots, I don't have the color of each wire in each of the twelve slots. so I am not sure the Seicane fix won't work.
Unless the years old Mediabridge wiring changes hot wired the amp I haven't done that.
It sounds like both of you are saying that at some point I will have to make some NCS changes. I have NCS expert but have never used it so that is going to be a bigger challenge if it is necessary to go that route. Seicane has not said anything about NCS changes. Their claim is if I wire in the "radio" to the connector I posted the picture I will have sound--that's their instructions for making their system work with DSP. Have the wiring changes made for Mediabridge eliminated that as an option if it ever was?
