This is a Car Mate TE-W7300. I was using it in a CNC25 Serena. It was working normally until I had a professional remove it this time. Everything in the photos is included. It seems to have the Serena harness attached. I'm not an expert, but I'll answer any questions I can, although my replies may be delayed. Please follow the 3N rule (no returns, no refunds, no exchanges).
