I'm not sure about the free phone app version of RWGPS having turn by turn navigation, since I don't use it. However, routes created with a free RWGPS account on their website give turn by turn notifications on my Bolt. Since I've only had by Bolt for a week, I created my normal route on RWGPS last night just to see how it works. Downloaded it to my Bolt and rode this morning. The Bolt doesn't do voice but every turn notification was show in advance of the turn.
