I just finished installing this package on my 2013 Harley Electra Glide, activated the radio, and it works. This package provides the basics of what is needed, and it wasn't hard to install. The antenna is especially nice for a motorcycle. Some things I did a little different, my installation was as follows.
Installed antenna on right handlebar; installed case/radio on left handlebar. The case blocks the view of the outside temperature gauge but I'm ok with that.
I didn't use the included power wiring opting instead for a two port low profile (2.4 amp/port) cigarette lighter/USB converter that I used with a separately purchased USB/barrel plug cable to go straight to the radio.
I removed the ignition switch and cover to run and tie-wrap the audio and antenna cable onto the handlebars over to the radio.
For wireless connectivity I also installed a SENA bluetooth transmitter that supports two headsets which connects to the Harley headset jack and allows handlebar volume controls to still work with the SiriusXM.
