Wire & more Wire.
Ok I am installing a Pioneer to replace the BOSS head unit. funny how Winnebago makes things so crazy. Instead of plugging directly into Mercedes harness they create this huge, long harness that goes to the seats, and loops back to the console? The antenna goes toward the seat (passenger) and then loops back up the console to the glove box and to the pillar window. Why all of this wire, and than not put in the wire for rear speakers. No wonder the steering wheel controls were removed, with this craziness no wonder the CAN network on the Mercedes chassis goes nuts. They made everything twice as long, and twice as difficult to do a simple connection of a radio, camera lead, and antenna. Sorry, I have worked in electronics all my life and cant excuse stupid.
