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?

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.
