Conclusion: The Magellan RoadMate 860T is a nice upgrade from the 760, but for the same list price, the Garmin C550, which also has text-to-speech, live traffic data, and a Bluetooth phone interface and can play music files while navigating, is a better value.
Pros: Excellent POI categories. Live traffic data with automatic rerouting. QuickSpell facilitates data entry. Text-to-speech conversion announces street names. Supports multisegment trip routing.
Cons: Can't play music while navigating. Awkward software application required for transferring music and picture files. Traffic data lacks list view.
