I installed the GL2way system last week and did ti without taking the cowl off. I reached under the cowl at the front to make the connection. after I did that, I tested the CB and it worked. This week I removed the cowl for the first time to wire in the GPS. I put it all together last night and everything works except the CB. When I push the CB utton on the radio, nothing happens. No CB in the display. I reconnected everything, the two big plugs on the bottom of the radio and the antennea. I also reconneced the intercom under the left pocket. Before I take it all apart again, any suggestions on what I might have missed?
