Hello, which GPS (graphic map on display) is the best for deaf drivers? I need to know. I notice some GPS have voice feature. I prefer them without voice feature. Can you find the brand/name of GPS for me? So I probably purchase the right one (s) someday. Thanks 

I don't want a GPS because they cost $500 for a itty bitty device. I'll wait until the price drops to $200 or under for a color GPS, not the cheap black and white ones.
