Hammerhead Karoo 2 is an option. $400. They have a much better screen, better map image, very good navigation and turn by turn. They update every 2 weeks so stay on top of bugs. Only downside is battery life is not as good as Garmin, 10-12 hrs, typical. Thats about what a Bolt can do. Or a Garmin Explore, $249. Designed for the touring market, doesn't have the power and workout functions, also about 12 hrs. battery life, can use a speed sensor. Good size touch screen which is useful for scrolling maps. If you can find one, the Garmin 1030 Plus was selling for $450, very good top of the line unit, 20 hrs. of battery. Not sure they are still available.

In my experience with multiple Garmins including a 1030 currently, the BT issues seem mostly solved. Mine connects with no issues and does Live Track reliably.
