Before you complain about the dealer, and knock the quality control, you should know that Canadian laws prohibit the "tampering" of odometers - be it either "rolling the mileage back" or adjusting it forward to match the recorded distance of the replaced unit. The software available to Canadian dealers's hand held tester unit does not enable the technician to access the control unit for that purpose. The service dept. should have stamped your service book to verify the speedo change, and to verify the odometer reading at that time. Check it out, and ask the dealer to do that for you if they neglected that important step.
