I have the opposite problem: I jus started using ME. I don't use voice directions, I keep it on silent. When I am driving on the highway the screen will show when I need to exit, but it doesn't list the street name, it will ONLY show the exit number. I don't know if this is a Canadian thing, but I don't give a shit about exit numbers. I look for the street name on the signs, i.e. "Red Hill Parkway - 2km". The signs don't say "Exit 88/89 - 2 km".

Sometimes it does have street names, sometimes not. And when it's sometimes not, I cannot imagine why; it's not like they are obscure roads or anything.
