Doing some tidying up in the shop and this was in my SENA drawer. There are 4 sena units here, there's a 20EVO, maybe two 20S's, and the other one is even older. Lots of wires and bits and parts. Thought I'd offer it here to see if anyone wants to put any of this back into service or scavenge parts. Of the 4 units I am pretty sure at least one is dead. It's dead Jim. Other simply were put in the drawer whenever I upgraded. I haven't tested any of them, won't guarantee any of it works. This will have to ship ground due to the batteries. How about $30 delivered to your door in the CONUS?
