No sound in dash speakers after replacing in-dash Jensen
I know there are several threads on NAV system removal, but I couldn't find the answer to my problem.
I'm replacing the Jensen with a Pioneer unit and have connected the speaker wires (green, white, purple, grey) to the new unit and, while I get sound to the "5.1" speakers in the living area (and the subwoofer works) the dash speakers are silent. Since I am only using one set of wires, I know it's not a setting in the Pioneer unit. There doesn't seem to be another set of wires for the front speaks and I had assumed that the crimped wires served all the speakers (front and back). For those of you who have replaced your dash units, any help? It's a 2015 Sprinter that had the Jensen VM9762BT.
There is one other harness that I assumed was unused, it is in the second attached photo. The other photo shows the maze of crimped speaker wires that goes to the living area speakers.
I've installed almost all of my car stereos over the years so I'm not overwhelmed or anything but I am (foolishly?) doing this while on the road.
Any help or suggestions would be appreciated.
