Jon, Glad you're here and you're "back in the saddle." Although you never completely left, it's good to have you back posting and available for those you have special audio connection issues. Now, I have a challenge for you. For years, EdSets has been selling a " MIC Splitter" that plugs inline into the GL1800 intercom and then goes into the MIC Input of a GPS. Years ago, I had this working perfectly on my Garmin 2820. But since then, I have tried getting it to work on a Garmin 550/660/665 and it just doesn't work. The volume on the receiving end of a call is extremely low and muted. Lewis has tried to figure out what the issue is to no avail. The easiest solution would be to go to a Bluetooth setup, but I don't want to use Bluetooth. I like my J&M wired headsets. My hope is you can come up with a solution that works, that's plug and play, and is simple like the MIC Splitter. Thoughts? Ideas? Do you already have something like this available? Welcome to the board!

They seem to have something in the software when the GPS sees 28mph+ the mic has a gain. From 0 -26 mph, never an issue on Charlies bike.

Bart....I think the issue is in the Garmin. They seem to have something in the software when the GPS sees 28mph+ the mic has a gain. From 0 -26 mph, never an issue on Charlies bike. I was doing some testing over the weekend and I was sitting still on the bike, engine not running. I "phoned a friend" and tried three different helmets, one with J&M 279's one with 584's and one with 629's. None of them worked. If however I plug in a microphone (one that come with my old Garmin Nuvi 7XX series), into the MIC IN on my 660, it works perfectly sitting still. I also ran the mic cord up the coiled cord of the J&M and taped the pickup inside my helmet, and at 60mph going down the road, it works perfect. So it HAS to be that mic splitter. The mic splitter uses an "induction" pickup to get the signal from the helmet mic and introduce that signal into the MIC IN on the GPS. That method just doesn't work. There has to be a better way to directly capture that signal and send it to the GPS. Maybe I'm off base, but it seems to me it should be an easy solution.

the headset mic has just too low an output to drive the input of most devices. mics put out 10mV at most. devices want lots, lots, more (10 to 50 times more). Kennedy has a box that takes audio out of the intercom , cuts it way back and presents it to the input of the gps. that module and a harness to connect it to the intercom and another harness to connect it to the gps and you are off to the races.

Jon, Tell me what I need to connect to a Garmin 660LM (part numbers) and I'll order it from you. I know a LOT of people would like the know the outcome of my install and test. Let me know!

The parts required depend on what features of the GPS and the bike that you are going to use. Drop me a note, and I'll put the appropriate BOM together.

Jon, I already have your IsoSet I got from you years ago so power is covered. I have the Audio Out from the Garmin 660 going to the AUX IN on the GL1800 so audio is covered. I leave the bike in AUX "ALL" the time. Now all I need is a better way to capture the MIC signal and send it to the MIC INPUT on the 660. I'm currently using that Mic Splitter I mentioned above. I need to take that out of the loop and use whatever product you have. Should be pretty simple. If your setup requires 12V, then I'll make a pig tail to split the switched 12V under the left pocket. That will give me a spare Hitachi 12V connection. During the install, I'll take LOTS of pictures and do another "HOW TO" and post it on the How To board along will all my other install tips. Thanks!

Well, I just got off the phone with Jon and got the parts list. I also got the prices. It's three parts. A CellSet unit which conditions the signal before sending to the GPS and two harnesses. One to go from the mic to the CellSet and one to go from the CellSet to the GPS. If you decide you want this yourself, here is what you need: 95258 - Intercom harness - $40 95416 - CellSet, MC/GPS-MIC - $60 95516 - GPS harness - $35 Total - $135 While I would really like to have this installed and working on the bike, $135 just to be able to talk on the phone while riding the bike is just not an amount I'm willing to spend. At least now, y'all have the part numbers and prices if you decide you want to make the investment. Anyone want to buy a slightly used Mic-Splitter? I have this one from EdSets available. $20 and it's yours.

Thanks guys. I hope to have the bike back by the weekend and will see how the new Zumo 590 works with what I have. If it is still a problem, I now know I have a solution. Given that we are on the road a bunch, I really want to have as part of my options a system that will be reliable to make a receive quality calls.
