DrIsotopes comments about the Wahoo having a reputation for greater reliability *can* be true, but it’s also dependent on which Garmin device. Some have reputations for being really flaky, others not so bad. My 810 sucked, my 1000 didn’t, neither does my 1030. The first 1030 was such a POS I returned it, got a 2nd and have had no issues. 820’s I read have issues, 830’s or Explore seem very rock solid.

The Wahoo Bolt I had worked really well. I think the concept of setting everything up on the phone is overrated, I’ve never had issues figuring out a Garmin. I returned the Bolt cause A) the maps basically suck. It’s a B&W image with very little detail and no street names. Completely road centric maps as well, so less useful if going into the woods and you cannot add different maps, Topo as example to a Wahoo and B) The Wahoo Turn-By-Turn display goes white text on black background, is very difficult to read with sunglasses on, and is something Wahoo doesn’t have any adjustment for. Thus I found it annoying to deal with and between that and crappy maps just gave up.

As the OP indicated he wanted some form of maps on screen, I’d recommend Garmin. Color does make a difference else Wahoo never would have bothered with the Roam. I would note to the OP though, that keeping the map displayed all the time EATS battery life. Thus do some thinking as to what you want displayed and why.
