GPS units all have compromises.... Thanks to Apple's latest OS 11.0.3 update, I can't get traffic on my Zumo 590... I don't know who is to blame, Apple or Garmin. So there is something to be said for the simplicity of using just the phone in and around cities. I view the newer "feature" of having to use a phone to get traffic data as a DESIGN FLAW! It was easier and more reliable with the traffic receiver in the GPS unit itself. Like my old Nuvi. Like my ancient Magellen.
