Talk to biketronics about their BT344. I installed the handlebar controls into my bars on my road king and then ran the wires into a BT 344. Ran that into a 2250 amp, I can now mount my phone, have Nav over the speakers, run pandora, or regular phone music through my speakers. Can control volume, play/pause, skip, while leaving my hands where they need to be. Was some work to add switches and pull extra wire, but looks clean and factory. Still buttoning it all up and waiting for a nice day to do a test ride, but it rocks I’m the garage for now. I can send a few pictures of the setup if that helps. Not 100% finished, but may be helpful for a start.

This is the module. Mike at Biketronics told me about it. May want to send him an email for more info. Pretty slick little module.

I have the instructions in a pdf for the BT344, if you want pm me and I can email it to you.

OE, buttons from harley
Bt 344 with my 2250 amp still have to clean it up a little, made it all with quick disconnects under the side cover, so the saddle bag can still be pulled off

It’s not really a handlebar mount kit. I bought the audio switches from Harley, installed them into the empty control holes in the bars, pulled extra long wires through the bars and down the bike under the tank. I then installed the bt 344 into my saddle bag. Would of also fit under the right side cover. Which I may move it there later. Then wired it all up to the battery and the bar controls. Ran the bt 344 into a 2250 amp and amp into the 4 speakers 2 in lowers and two in bag lids.
