I ordered a hand held radio for my trip in my rzr as my buddy had your radio's installed in his rzr when i received my radio it didn't have an antenna so i had to quickly express ship an antenna i found on ebay in hopes it would make it for my trip it did the very day before i left on our trip we tried to communicate through the radio's and was an epic fail wether it was his set up or we just didn't know how to operate them we didn't waste any more time trying to figure it out radio seems pretty complicated we ended up using cheap frs radios the entire trip had me wondering why i spent so much on a radio
