One of the things I like about the SMH10 is that the firmware can be updated as Sena fixes bugs or adds new features. The firmware is software on the device that makes it work. For example with the April 2012 update to v4, they added 4-way intercom and 3-way phone-intercom conferencing. The 3-way phone-intercom is interesting as it means you can bring your intercom partner into the phone call. The current version right now is v4.1. You can read the release notes here for v4.1.
To update the firmware, you have to have Sena’s management software installed. To download it, you must have first registered your product which is relatively simple. It only requires a name, email, country, model, purchase date, and purchase place.
The software to update the SMH10 software is on Sena’s website here: http://www.senabluetooth.com/support/pre_download_document.php
After registering, you can enter your email address to get to the software. At the time of this writing, there is software for both Windows and OSX. I downloaded the Windows 7 64-bit version since that matches my computer. They have a very complete site with both a PDF manual for the software and videos here: http://www.senabluetooth.com/support/SMH10_Manager_Software_Manual.php
With the software I can enable and disable features in addition to updating the unit’s firmware. My units came with v4.0, so I updated them to v4.1.
The update process was simple. From the time I downloaded the software until I had both units updated was about twenty minutes. Easy.
These are the steps I followed. It looks like a lot, but again, it about twenty minutes to do it all.
The blue light is on, so it is all charged up and ready to go!

It will copy a bunch of files and start installing a driver.

Holding the phone and jog dial in until the LED flashes violet (a few seconds)

I saved it to the default location
It handled the download for me.
It starts the update procedure
Press and hold the phone button.
Firmware update begins. While this is in progress, don’t unplug it. I went and got a drink. It took a minute or two.
Press and hold the jog dial and phone button.
Click ok. I followed the advice and re-paired my phone.
Since I have two, I clicked yes and followed the above procedure for my second SMH10.
If you click Device Setting, you can enable and disable features.
I wanted to enable VOX Intercom, so the intercom to my wife would start with me talking instead of having to push the jog dial. It will then end after 20 seconds of silence. This works great, so I can keep both of my hands on the handlebars.
Click Save and then OK.
Settings will be saved after the device restarts.
Unplugged and then turn off and on to get new settings.
Re-pair and ready to use again. A very easy process.
