Speedbox 2 LED No Power, not a light?

[Goodair]

I ordered a Speedbox 2 for my Yamaha PW LED, simple install with battery taken off, after install, nothing turns on, I am on my second Speedbox 2.

Do you know if Yamaha or Haibike updated their firmware to defeat any dongle attachments?

I had same issue.. lasted just 5 minutes.. second one is on the way.. hopefully does not die on a ride..

Got second one today.. seems to work. does not display MPH correctly, but this is known issue. I run a GPS so i dont care this part.. seems to exceed 20 mph nicely.
