>>9990333There may be some kinds that you can plug into a USB port, but I've never had one. This one I hard wired to my battery, so I can turn it on without turning the car on. It's still super easy. It took me 30 minutes from start to finish.
>>9990334>What do I need and how much does it cost?You need the whip (pic related) and the actual radio and mic. The unit I have pictured in the OP, plus the antenna, cost me about $60 total. They can be found cheaper though, they will just have shorter range.
