For those here that may have one of the nuvi 5xx series crossover units (likely not many, going by the lack of questions/comments), TTS voice support has been added with the newest firmware v3.40. It's quite rare for Garmin to add new features to existing units so this is a plus for both Garmin (customer relations) and the end-user (customer satisfaction).
