I got the Magellan Road Mate earlier this week and the news on this unit is not good for Convertible owners. The voice prompts are very quiet and you can barely here them.I am picking up the Garmin 2620 today and will compare both in the car at the same time. Anyone own either of these units? The Magellan would be fine in a coupe but I can't hear the damn thing in a ragtop. The POI's are pretty miserable on the Magellan as well. If anyon owns the Magellan please let me know your opinion on the unit before I return it.
