A bunch of us picked up Cardo Packtalk and Cardo Packtalk bold units before the WeSTOC trip this year. With the DMC mesh technology, we were able to keep in total touch with each other, even when 5-7 of us were spread out over long distances. The dropouts came when people in front of you went around mountains.
I paired up to my old Garmin 2730 for XM music and GPS instructions using a combo of fairly high-quality devices that altogether cost me about $67. Here's a description of the system that I posted on ST-Riders.net;
So, the new task is to get the 2730 to talk to the Cardo unit. It turned out to be pretty easy, and pretty cheap. Here's what I did.
First, the Cardo unit can talk to 2 different Bluetooth (BT) devices, both in stereo, plus talk to up to 14 different riders using their mesh technology.
So the first job was to pair with my smartphone, giving me the ability to send and receive phone calls. That was easy, the unit paired right up to my Samsung Galaxy and tested fine. If you wanted to get your tunes and GPS directions from your smartphone, you could stop right there and have a great system, which is what Corey is doing.
At first, I tried just using a BT transmitter to send the output of the 2730 to the Cardo. That paired up fine with the Cardo and was pretty easy, but the volume was inadequate. So I bought a really nice little amplifier to put between the 2730 and the BT transmitter. I also got a little noise filter, which was good, because I needed it to eliminate a buzz in the system.
Miniature electronics these days are amazing - everything works good and sounds great. So I'm all set to go. The components all fit in an old Otter box I had laying around, and that tucks into a corner of my tank bag. Everything runs off USB power.
It was also pretty inexpensive. The BT transmitter was about $25, the Amp $35, and the line filter $7. So about $67 total. We got a decent deal on a pair of Packtalk Bolds for $370 ($185 ea) and I splurged on the dual driver S-buds at $209. So I have about $465 into the entire system. Less than I've spent for other systems, and almost half of that was optional (the s-buds) as the system comes with headsets.
The pic shows the line coming out of the 2730, thru the noise filter, in and out of the amplifier and into the (round) BT transmitter.
