Hi all,

Only received my Karoo 2 a month ago but experiencing problems with sensors. Not sure if it's since the latest update....which only installed last night.

Symptom: No speed / distance registered on unit during ride whilst sensors were enabled. When I disabled sensors - speed & distance started registering OK.....although the total ride distance registered/uploaded to Strava was 18 miles short....

Paired devices: Garmin Speed/cadence sensor & HH HRM strap.

Have already notified support directly, but just curious if anyone else is experiencing same. Realise this is a new product so expecting teething troubles...although I was an early adopter with my Wahoo Bolt and rarely experienced any such issues.

Anyone else seen this ?

  I have found that the order of the sensors matters. I the speed, cadence, HR power all before the GPS sensor and the radar sensor. Hope this helps.

  Update: Still not working.
  tried
  1 soft reset,
  2 hard reset
  3 changed sensor order
  4 verified both sensors with Wahoo bolt
  5 swapped karoo 2 unit
  Still same issue

  When i originally got unit the speed didn't register & i managed to switch gps off & on again & that worked... but since the updates i can't find that setting... Think it mentioned glonass / gps option? Not in sensor section. Anyone know where this could be? Or has it been removed?

  Update: Isolated the problem to my Garmin GSC-10 speed/cadence sensor. When this is disabled, speed registers on the K2. When it is enabled, cadence registers on the K2, but not speed.

  Anybody else seen this before ?

  Something fundamental is wrong here.
  Why would it matter what order they are connected?
  I have mine paired with speed sensor and power/cadence sensor, but it is on a different bicycle. When I left to ride on bicycle with no sensors I got no speed - 0.
  There should be sensor activation - sensor active and sends data, yes - go ahead and use it, no - back to calculation from gps (speed) or leave as 0 if not active.

  I have an issue with Wahoo speed and cadence sensors not picking up during an indoor velodrome session. I have been told GPS has been disabled inside the Olympic velodrome in london due to safety reasons so I bought some sensors to track my stats. But nothing seems to get picked up on the Karoo 2 from the sensors.
