What is the Sena support like? Is there someone who can talk you through the set up?
My unbiased opinion is that nearly all modern intercom systems are too clever for their own good and too complicated for the average user. Or at least, dim ones like me.
I love the clarity and range of the Sena.
I used to love the simplicity of my old Autocom Systems but not the range nor the cabling.
I'm normally good at spatial awareness, hand eye co-ordination and dexterity (removing and refitting MGB GT manifold to down pipe nuts/bolts from above anyone?) but the complexity of the controls on the Sena leave my fingers in a total state of bafflement.
I guess if you use all the functions every day it gets easier; assuming you can get the functions you want to work
