Audio prompts for plan workout steps

This is a great question. I would assume you would first need the 255 music, unless the non-music 255 has support for headphone pairing? Does anyone know if there are audio prompts on either version? 

Yes you do, for HR or pace and power (for cycling with a power meter)

Without headphones if you have a phone with you, they come to your watch via Garmin Connect, or your headphones with the music model.

EDIT: Sorry I missed you were talking about Garmin Coach as I just read the title, I do not use Garmin Coach so can't confirm. It does work for normal workouts.

So, just to be clear, the prompts you get are voice prompts, not just sound alerts for me to look at the watch?

@SeeParRun have just posted a demo so you can hear it (if no audio from the forum, the Youtube link should work)

Thanks. Do you know if this is similar for running workouts / coach? 

For running you get HR or pace targets read out, similar to the above - at each workout step and if you go over or under the targets (voice alert if you exceed the HR target etc)

I do not see any reason why Coach would be different if they appear as workouts but Coach isn't something I use.

Very helpful. Weirdly I cant find the workout instructions as option under audio prompt on my 255 non-music. just Power, heartrate and pace. where do I activate this? it would be very helpful for my rowing workouts.  I have firmware 10.10 installed, found this option in the manual, but not on my watch nor in the app.

The manual states it, cant find the workout prompt option anywhere...
