I asked my wife for a new radio for my truck For my birthday . I was expecting a typical Cb. She buys a top gun predator. I’ve never used a am/fm with side bands. How in the heck do I just use the cb radio. It was peaked, tuned, and modded by a brick and mortar cb shop off of I80. Please help. Way too many knobs and switches that I’m not used too. Please help
