Bluetooth

So, I got me this nifty dual channel Bluetooth gizmo to get connected to the stuff buried down below the left cubby. Now I have access to all the audio the bike has to offer, including the iPod in the trunk.

Slight hitch. There is an electrical whine that seems to be in tune with the rpms of the bike. Interference from the alternator, I supppose. I’m wondering if it may just be the Sena Din cable or the Bluetooth unit itself. I’ve never noticed any interference before, because I always just paired my Sena 20S to my phone. Now with the gizmo transmitting the infotainment audio, it’s definitely noticeable, although it gets buried in the background as I crank up the tunes a bit. Is there some sort of inline isolator I could use to eliminate the interference?

Anyone out there experience the same issue?

I saw those. It worth the expense to try one out. Thanks.

Yes, there are cheap and last about three rides until they stop working. Made in China.

Installed mine when I did the Bluetooth thing 3 years ago. It's been on several cross country/wet rides and it still works fine.

Seems like we always hear about failures but things that work as advertised... not so much.

Hi Switchmonkey

If you used the power supply below the left cubby this is why you have the whine thru your headset.

It is because that earth is not a good earth , run a new earth back to the battery and the whine will disappear.

I have learnt this thru previous experience with my B.

Hope this helps

Well, they did work, they just did not last.

I bought this one from E.C. and had no issues with interference now for two seasons.

Great point about the ground a lot of problems pop up from poor grounding.
