Hey All
Dos the Sena S20 work ?, Any problems I need to know about ? .

I've been using my 20S since mid-2014 and have been pleased with it. It's important to fire up the Sena Device Manager and let it check for firmware updates, since there have been several since I received mine.
Due to its capabilities, the device is a bit complicated and takes a while to learn its operation.
