Iím a tech head, and often an early adopter of new technology. I would love one of the new heads up display unit that universally fit full face helmets. Both Eyelights and NUVIZ offer a motorcycle head-up display with integrated navigation, communication, camera and music. They connect to your smartphone via Bluetooth.
The NUVIZ is the larger of the two, but comes with an inbuilt camera, however the Eyelights comes with microphone and speakers, and can be operated by voice command. Both use a small prism that displays a screen. Both are around the $700 but these price should drop over time.
