Forerunner 165 music - Garmin coach

Hello, 

I just bought the forerunner 165 Music. I love the option training with Garmin Coach. But I have some troubles. 

A friend has the forerunner 255 music and use the garmin coach. He told me his app told him his pace during the training. 

By exemple, when he's running, the app says if he runs too quick or not on his bluetooth earphones. I tried the "alarm" notification but it doesn't work

Another problem on my Garmin coach : The pace I have to do doesn't appears on the program on my PC or my phone. My fiend has the information (by example : 10 min on 5.45"/km) when I have only the information "quiet course" with no pace information.

I don't find this option on my forerunner 165 music. 

Does someone knows how can I fix it ? 

Thanks a lot
