How many on here have installed aftermarket radios in place of their HK units? I'm interested in hearing what you did and how you hooked it up. I know there are some companies making install kits that allow you to use the factory handlebar controls on the aftermarket radios. I'm looking to go to an aftermarket radio that is XM capable and will allow me to use the factory controls. I'd love to see pics if you have them and if not, a description of what you did along with total cost. Thanks!
