I attempted to do the very same thing using my Ipod and JBL ChargeII, but it just cuts out most of the time. I really don't think it is interference with bike computer. I'm thinking it's power line interference myself. I finally mounted the ipod near the speaker on the down tube and away from the computer on the bars so I can use a wire connection and it works awesome. I've been told by friends that they also have similar problems with bluetooth in cars as well. I do use BT connection while using my indoor trainer and it works great there.
