Add a wind instrument w/o removing mast?

I have a 2004 C387 without a wind instrument. I would like to install the Garmin GMI 10. Does anyone have experience fishing the cable down the mast? I had a local electronics company look at it and they said the mast would have to come down. Then they recommended a wireless Raymarine. I have a coax TV cable up the mast that I do not use. Could that be used to pull the new wind instrument cable down?Thanks, John Kaplan
