I did mine myself in center council of my 19 Trailboss. Went really well with a little work and some ingenuity! Cut apart a triple coil charger off eBay. Paid $12 for it a couple years ago and wasn't using it anymore. Opened up the bottom side of the lid, ground it out with a Dremel tool, glued the modified charger in place, ran a charging cable from the USB in the counsel to the charger thru the hinge, put it all back together and it works awesome. Radio has to have power to it for it to be on!
