Installed on my 05 FLTRI Harley and was super easy install and works awesome. This unit has Bluetooth or aux capabilities and my bike came with a hogtunes gauge controller so I run that with the aux so I can use it as a remote instead of the one provided. You can also use no remote and just operate with your phone.
