My GPS has a radio in it ...however I do not use it at all mostly because I hunt alone..always. I wanted a good GPS and the ratings on this where outstanding for both radio & GPS. I have other friends that swear by this unit and they hunt in simular terrain that is not radio friendly and they have no problem. Its pricey but I have done the homework..you can check it out also.
