GPS: TomTom GO 720 vs Garmin Nuvi 250w?

I have a garmin 340c, but it has voice to text... I would not recommend anyone buy a navigation system without that feature... You don't need to be looking away from the road constantly to look at your Navi to determine what road you're supposed to be turning on. Also exit ramps etc change all the time so sometimes it may be off by .10 of a mile and without it specifically telling you where to turn you could easily miss exits etc. So between your choices I'd go with the tom tom... but look into current prices of the 340c, I love it.
