Sometimes it amazes me that bluetooth is so ubiquitous because it works poorly much of the time. I have to forget my car from my phone once a week, for example. I had to spend 5 minutes getting music to play on my bluetooth headphones yesterday. I think my garmin watch and 830 gps work okay with bluetooth, but I had to disable notifications on the 830 because CVS had a bad habit of calling me for no reason when I was on early Sunday morning rides.
