Did you set the appropriate alert to come through on the Garmin Connect Mobile on your phone? I had to select the text app I use (not my phone's standard)
I picked up a 235 a couple of days so far and really like it so far. One thing that I haven't been able to figure out is how to get texts to come through on it. The fenix 3 hr that I'm trying out right now does it perfectly. Any help would be GREATLY appreciated!
