I have a question for someone that hopefully understands this.

So i have an aux cable, it allows me to connect my phone to the bike and listen music through the bike speakers.
I also have a cable i wired into the bikes communication wires that allows me to have the bikes radio go through a bluetooth transmitter and I can listen through my Sena Headset.

Now, what i thought i would be able to do is connect my Phone to the Aux cable, play my sirius XM music from my app, and because i have the cable tied into the bikes comm system and a bluetooth transmitter, be able to listen to the sirius XM music through my Sena Headset. Now i know i can connect my headset directly to the phone through bluetooth, but the bluetooth transmitter is dual channel, so if it worked, i would be able to have the Sirius xm transmitted to both mine and my wife's Sena Headset.

For some reason , it does not work. I don't hear anything but maybe slight static, not a lot but no Sirius?

I don't understand since each cable when used on its own works. Aux to bike, works. Comm to bluetooth transmitter to Sena headset works.


???

Any ideas?

Are you connecting to the bike Aux cable with a 3.5 mm jack in the phone? If so, it is likely that all of the phone output is being routed thru that connector. They are designed this way so a headset or external speakers connected to the 3.5 mm jack will silence the phone's speaker. I'm guessing it also over rides the BT connection, too. It probably never occurred to the designers that someone might want to use the jack and BT at the same time.

Yes, I'm connecting to the 3.5mm jack, but then i have output from the bike to a bluetooth transmitter that my Sena Headset connects to. So i thought, theoretically i should get audio

So check it like this.
Turn on the radio and get the bluetooth playing to the helmet headphones.
Then plug in the phone aux cord.
If the radio stops you have your answer as stated above.

I don't have the comms system, so I can't help you troubleshoot that. Like vulcandoc asked, can you get the bike radio to play in the helmet with the phone not plugged in? Do you have BT turned off on the phone while you are doing this?

Shouldn't you and your wife's Sena units both be able to play music directly from the phone by BT without all the complications?

How would you connect two headsets to one phone?

I got it to work,but when my phone charging cable is plugged in there is a lot of static?? I used a sheilded cable for the aux cable?

I know that many couples use BT share music from their phones in their headsets. I don't know how it is done as I ride solo, but there should be some instructions with the Sena units on how to connect them for communication and for sharing a BT stream. It's all in how they are paired with the phone and each other.

The static sounds like the static may be coming from a ground loop. Another 12 V to USB adapter (I assume that is what you are using) may clear it up, too. If not, look up ground loop isolator on Amazon. You may need to install one in line between the phone and bike. The ground loop interference could be coming from a bad ground that could be anywhere on the bike, but may be associated with the radio. Without some testing equipment, it may not be possible to find out exactly where it is coming from. Sometimes they are easy to find, other times, not so much, but the isolator should help.

So unless you have Samsung 8+ you may be able to connect to two bluetooth devices,but only play audio through one at a time. I will however see if i use media sharing on the Sena 20s if that works with the Sirius app, it works for the default music app, but not sure.

That may be the solution

When all else fails, read the directions. :wink2:
