This is a video on how to add talkback and peak your Uniden PRO 520XL. I made this video becasue I was tired of hearing about how everyone who has these radios should just throw them away. NO! they are OK radios for what they are and you can get about 15-20 watts peak out of them with great sounding audio. This may also work for the 510 if the components are in the same location. I don't have a 510 so I don't know.
