Hello guys this is my first post here. At first i want to say that i am amazed after buying the garmin 235, Before i had the garmin 305 for at least 10 years and i was very happy with it. But.. time is moving forward. So basically now i started to learn the more features of the 235. One feature i am interested is the my personal workout. I create a Home bike program with 30 second in red heart rate zone, and 30 seconds rest- or yellow heart rate zone. the problem was that i had to look all the time the watch. Now i discover the voices messages that allows me to hear when a round (timer) is ending. First i want to say that when the round is ending there is sounds but not vibration. where i can enable vibration ? and is there any change to edit or download voice messsages so i can here , not Second round but REST or third round - Start?
