rickmoen Posted March 17, 2012 Share Posted March 17, 2012 Hello to all Bluetooth Specialists, Here's a problem that has me stumped. I have a Zumo 665 with XM radio, Nav Weather, and traffic. I know that the placement of the GXM40 is critical to its working properly. I get my sounds through a Schberth C3 helmet with their bluetooth SRC system. I also have a Nolan 102 that is Autocom'd with sound going through a new (1.5 year old) SuperPro Automatic. I prefer to wear the Schuberth helmet with bluetooth, but the XM signal strength indicates 0 to 1 bar and often cuts out or says No XM Signal. Te weather and traffic icons do not show on the map screen. When I wear the Nolan with its hardwired Autocom system (and bluetooth disabled), the signal strength jumps to the full three bars. Right now the GXM40 is mounted on the clutch reservoir. I've also had it on the top of the big top case at the rear of the bike and just under the windshield at the front of the bike - same results. It seems pretty obvious to me the bluetooth signal from the GPS to the SRC system is interfering with receiving the XM satellite signal. Finally, here's my question: Is there some sort of electronic filter that I can place somewhere in the system that will separate the XM signal and the bluetooth signal? The easiest solution would seem to be to Autocom the Schuberth and skip the wireless SRC system. It nice not being tethered to the bike by a cable, but is not a deal breaker for me. Thanks in advance for any help or suggestions. Rick Link to comment
SageRider Posted March 17, 2012 Share Posted March 17, 2012 I would try moving the GXM40 puck location. I am running a Zumo665 between the handle bars above the ignition key with the GXM40 puck on an RCU shelf on the fairing. The Zumo is connected via bluetooth to my Autocom. My AKE headset is also connected to the Autocom via Bluetooth. I also have a Valentine One radar detector and a HAM radio hard wired into the Autocom. I am not suffering any XM (music, weather or traffic) signal issues with this configuration. Autocom is a Pro 7 Sport with Bluetooth device adapter for Zumo, and Bluetooth headset adapter. Due to this Autocom's older design and limited inputs, the only issue I have with this configuration is that my radar detector gets lowest priority of any device. Link to comment
rickmoen Posted March 17, 2012 Author Share Posted March 17, 2012 Thanks SageRider, I moved the GXM40 from the clutch reservoir to the BMR shelf, where the GPS is mounted. The signal strength now shows between 1 and 2 bars, with 2 bars showing the majority of the time. There is an occasional dropout, but it is much more useable! The SRC software has been updated to v3.0, for what it's worth. Thanks again for your suggestion. Link to comment
SageRider Posted March 17, 2012 Share Posted March 17, 2012 You might try playing around with other puck locations to see if you can get the XM signal indication all the way up to full strength. Link to comment
Runnor Posted March 18, 2012 Share Posted March 18, 2012 SageRider, I was very interested in your advice, as I am just now at the point of deciding on an autocom, garmin665, and radar detector for my new-to-me 2010 R1200RT. Where to mount these devices is a big question for me, and then how they all connect is the next question. I'm also a ham, KC0DT. Any advice would be appreciated. Thanks, John Link to comment
SageRider Posted March 18, 2012 Share Posted March 18, 2012 John, My Autocom with both bluetooth adapters, my ham radio body with my custom isolation circuit, my V1 audio and power adapters, and my power distribution ( FuzeBlock ) are all located under the passenger seat. I obtained a piece of flexible plastic, covered it in high strength Velcro loop, and cut it to fit over the rear fender area beneath the passenger seat. I then used the mating Velcro hook pieces for attaching the individual components. My XM antenna (screwed on), Valentine One (Velcroed) and ham radio face plate (screwed on) are all on the RCU shelf. My GPS uses BMW's stock GPS mount on the fork crown. I mounted a non BMW Zumo665 with it's stock bracket to the BMW Mount. My 2M/440 dual band antenna is located on a custom milled bracket attached to my rack. Excess cable from the various devices is stored in the area above the front shock top mount under the top center tupperware. Link to comment
RLJ Posted March 19, 2012 Share Posted March 19, 2012 Michael I have been wanting to get a Sena bluetooth helmet sets but have been holding off because I am unsure about getting reception to rider and passenger from the Zumo 550, and XM. I currently have a Autocom pro 7 sport also. How are you getting reception from the Autocom via bluetooth? Would this be a way to have passenger and rider receive the XM and Zumo? I am tech challenged and would like to get ride of some of these wires. Link to comment
Runnor Posted March 19, 2012 Share Posted March 19, 2012 Michael, that's lots of good info.so you dont have any wires connecting to your helmet? John Link to comment

Hi RLJ, To get Bluetooth to a helmet-mounted Sena BT device from an Autocom Pro-7 Sport use two Wire-3A units - one each for rider and passenger. It seems quite easy to fit. http://www.autocom.co.uk/AutoComWire3.htm Hope this helps, John Link to comment
SageRider Posted March 19, 2012 Share Posted March 19, 2012 RLJ, John's answer is correct. Headset Adapter. 1 per headset Device Adapter Use one to connect to Zumo via bluetooth. By the way, I have an original version Sena headset. It's a fine headset, but I did not like having that big lump of plastic on the side of my helmet. Since I was spending cash like there was no tomorrow anyway, I acquired an AKE Bluetooth Headset along with a larger battery. Link to comment
SageRider Posted March 19, 2012 Share Posted March 19, 2012 John, Correct. No wires to helmet. Link to comment
rickmoen Posted March 20, 2012 Author Share Posted March 20, 2012 Just a quick note to update the tread. I have moved the GXM40 to various locations and finally mounted it to the left of Zumo on a BMR shelf. I also installed a Wire3A from Autocom. This allows turning off Bluetooth in the Zumo. Signal strength from XM went up immediately to between 2 and 3 bars, mostly 3 bars. The Wire3A is paired to the Schuberth SRC. The SRC thinks the Wire3A is a GPS, but so what! I'm wireless and have great sounds through this system. Thank you SageRider for your timely advice. This is the greatest board ever! Rick Link to comment
RLJ Posted March 21, 2012 Share Posted March 21, 2012 Thanks for the info guys. I will look into it and try to get this ironed out before my next trip. Link to comment
