CB is a 40 channel two way radio in the citizens band on 27mhz. Walkie talkie is a term that applies to a lot of hand held transceivers which can be on the CB frequency or FRS or GMRS or Nextel uses the terms as well. So the name "walkie talkie" has become overused which leads to confusion. Currently when you search for walkie talkies you find those crappy FRS radios which you don't want because you'll be lucky to be able to reach a person sitting in the same car as you with their limited range. He's probably wanting you to buy an actual CB radio.
