Certainly, if you bought the gyro retail from the same shop that installed
it, the shop should replace a defective unit free of charge, including labor
to R&R, and they should do all of the dealing with the manufacturer for
warranty adjustment. If you simply hired the shop to do an install of a
unit you bought directly from the manufacturer, or elsewhere, it would be
quite reasonable for the manufacturer to refuse to pay for R&R of a
defective unit.
