You rip out all the add on bits that are left over, get a pair of SMH10 Bluetooth headsets for your helmets, and a SR10 interface to a CB radio if you think you absolutely must have it.

Unless you are putting about below 35 mph the bike's stereo is useless. Bluetooth to your phone will give you better music than you can get from any BMW stereo. Want Sirius/XM? just install the app on your phone and listen. If you really want to listen to FM radio you can use the FM tuner in your headset.

The BMW stock radio is designed for use with their wired headset system if you wanted to hear the music, you can buy a $600 wired unit to replace what is missing but you then can not have Bluetooth for the helmets only wires. Add $295 for the Bluetooth to the phone that will only let you answer calls.

If you want the best intercom system with bike controlled music, then that is wired headsets and about $800 to $1000 in parts if you install it all yourself. If you want Bluetooth you really need to abandon what is on the bike and go pretty much as a complete separate setup, Fix the bike stereo so you have tunes to listen to while you wash it.

I just went down this road and spent a lot of money on trying to make the on bike system work the way I wanted. It's all in a pile on my floor waiting to go on ebay, and I have a pair of SMH10's on the way with a SR10 for interface to my Ham Radio two way. All of it fits in the tank bag, I can listen to XM,FM,all of my music collection on the phone, Pandora, etc... the wife can listen to her own music or chat with her friends on the phone, or as she prefers, talk to me so I cant hear my own music.

Bluetooth does not let you listen to music and intercom at the same time, so keep that in mind. Only a wired system will mix the music in with the intercom.

But the SMH10 will let me make a phone call completely with my voice, I can also control the music by play/pause/etc by voice as well (I use the iphone that has voice control)

So you actually need to make some decisions, is having music from the bike in your helmet very important? if so then your only choice is wired. Look at Autocom SPA and the Autocom Bluetooth phone adapter to hook in your phone, also you need to get the autocom radio adapter to hook to the CB, then another autocom adapter to hook the stock stereo speaker outputs into the autocom. You also will want to get a set of coiled headset extensions at $50.00 each.

I found it a lot easier and cheaper to just abandon everything on the bike, and I end up with a better system that does more.

What's the easiest/least expensive way to bring everything else together, and have bluetooth capability so that both riders can use their phones as well as the other features without running dual headsets into both my helmet, and my wife's?

I worked on my German cars and bikes for at least 20 years with SAE tools before I spent money adding metric tools - when I needed a 15 mm just bought a 23/32 in. socket - so see what you need or splurge for a complete new set of tools

Thanks Jack. I hope I can help to others eventually.

I have to admit I'm a little intimidated since I've never worked on anything German before, and although I understand basic wiring, and circuitry I'm not up to speed on a lot of the gadgetry.

But once I build up a little steam there's no telling how over the top up get. :-)

Good deal, your going to do well here...

Sometimes just a little help gets you over the top!!

I chose a different path and think I made a good choice. My motorcycle didn't have a CB radio, but after having them off and on over the years, find I really never used it. With phone technology now reaching most areas, a CB is heading towards being archaic.

The audio on my newly purchased bike was very scratchy and I didn't want to take my bike apart first thing to find the problem. Instead, I bought a Sena bluetooth system for my pax and I.

This unit is very easy to set up and operate. The Sena allows intercoms between up to four persons so a small group can be on a single network but not all have to talk at once like FRS comms. One person can to talk to any individual or everyone at the same time.

The Bluetooth allows me to use my phone, MP3 players, and GPS. The Sena provides independent volume controls for each unit which is a major bonus. In town, I listen to Pandora or i-heart radio on the phone and MP3 on trips.

It also allow connectivity to devices like CB and two-way radios either through bluetooth or wired directly to the headset so you won't have to sacrifice CB if you don't want to.

I have since found and repaired the motorcycles' comm system but the Sena is still more convenient because I don't have to plug into the bike, and I don't have headset leads dangling from my helmet.

Battery time listening to music or intercom 100% of the time has so far surpassed 11 hours which is my longest riding day so far. It's a good piece of gear and allows some real flexibility.

The BMW radio and comm system is really good and probably offers better sound quality overall. If I were a real purist or hadn't lost so much hearing (aircraft mechanic) I might be tempted to use the BMW comms but can only hear the difference when the bike is still.

Just my 2 cents. You might want to consider opting for more flexibility.

I have the sena smh10 and sena sm10 and just got my lt, I need to spend some more time with it but I think I can bluetoooth the bikes radio and cd player and cb into the helmet.. as well as gps and radar detector... but like I said.. need to spend time with it

Hey Dick,
I'm not 100% sure about volume control since the speakers aren't very loud at all until the bike is at highway speeds. If there are additional settings that I'm unaware of I'd be anxious to check those as well, but I fear the rear channels are out since that seems quite common.

Concerning the lack of sound from the rear speakers, I'd pull the rear seat and make sure the electrical connections from the bike to the trunk are good.

Radio: currently has no rear sound (haven't had time to determine if it's speakers, wiring, or radio that is the issue).

Hi, Dale. You have the radio op manual? If so, then you've prolly read up on the fade/balance feature of the radio. If not, then there is a procedure to mute the rear speakers OR the front speakers. My manual is away at the moment, so hopefully, if you need the instructions, someone with the manual handy will post up. Good luck. And do enjoy the bike once you've got everything sorted.
