Direto connection to Garmin 920XT

[richard.baker]

I have connected my new Direto to a Garmin 920xt.
The power reading is spot on, compared to Myetraining software.
However, i am getting an extraordinarily high speed reading - 4 times greater than the Myetraining software.
I am only using the Direto's speed cadance sensor and power meter.
Any suggestions?

Probably you haven't put the correct circumference value in the Garmin.
When you use non elite devices or applications, you have to consider the internal ratio of the trainer.
For Direto, you have to use a value equal to your circumference/12.1.

Thank you for the prompt response.
I did 'play' with the wheel circumference setting in the Garmin.
Eventually i used 175mm which in turn matched the speed reading on MyeTraining App.

I’ve had exactly the same issue! Is there any way someone could give me a step by step breakdown on how to fix it please? As you can tell, technology is not my strong point! Many thanks in advance!
