I have a new 8900 and have been using Mapquest which I originally purchased with my older 8320. It works fine, but it will be expiring shortly, so I thought I would try the Garmin Mobile. It works OK except that the spoken voice has a problem. It isn't just tinny, but it has some kind of squeal that makes it almost unusable. Mapquest or MP3 voice files do not have that problem. Has anyone else noticed this?
