Video shots -Wind Noise elimination

[mcwho]

I have taken a few videos with my Canon Power Shot. It has hi res vid and stereo sound. Normally the video is good. I am trying to get a vid from inside the car, with the camera mounted in front of the passenger roll bar. I don't have the windshield installed as yet.

It appears as the mike is on top of the camera body next to the on/off and function button. I have had no luck getting a good video AND good sound. My pipes are kinda quiet and would like to hear them, this last go I put a piece of tape over the mike.

good video but no sound or only wind noise.
