RAM mount into the left mirror boss. RAM radio mount onto the ball with a three inch extension. Prior to that I kept the handheld in the tank bag. Much better reception up on the handlebars. I never mounted a handheld CB only an ICOM GMRS. I could never get my Midland handheld CB to integrate properly with the BC3 intercom. Primarily push-to-talk problems. Eventually, I got the J&M CB which also mounts on the left handlebar above the brake reservoir. Fully integrates and works very well. Very big bucks though. I only use it when riding solo to monitor truck freqs.
