I've been using the C3Pro with added SRC Comms. Purchased in Canada. two years later the sunvisor wires just collapsed. This may have been my own fault for closing the visor by pushing it back in rather than using the knob on the side. In Chile i took it to a shubert dealer and the visor system was fixed for $60USD (mas o menos). i didnt notice it at the time but the tech broke one of the retaining pins for the comms collar. it still stays in place. I just wished i'd removed it myself before handing it over for repair. Im going back to the store to upgrade my wife's old HJC for another C3Pro. Based on what've read here i think the C3Pro is a proven design and it works well and i know my wife will enjoy the new quiet....even with the SRC System connecting us. Imagine a world where all Comms gear was compatible with one another?
