I didn't install it buy my dealer says it was a bitch. The phone works pretty good if you have a full or 3/4 helmet. With a 1/2 helmet it doesn't work near as well. With the cellset you can also here commands from your Zumo through your headset. It will interupt the radio and when the zumo needs to give commands. However, it doesn't do the same through the speakers if you don't have on a helmet. On the other hand, if you want to just get directions and have the zumo interupt the radio then HD just came out with a wiring harness that will do the same BOTH through the speakers and headset and much cheaper. I have an '10 Ultra and the new wiring harness would work on my bike. Don't know about yours. If you are interested in the Cellset call Sean @ Cycle Gadgets and he'll give you some info. Some guys swear by it. Hope this is clear as mud.
