I'm trying to enter a highway address into the navigation but it won't accept it. I'm trying to find an address on Rt-46. If I start to enter RT it wont go any further. It doesn't even accept ROUTE. The weird thing is that if I do a POI search or a phone number search it will find the location and list it as being on RT-46. Why won't it let me manually enter the address? The nav is on an 04 model.

 

Try entering just the 46 and not the RT. It should then list the road you're looking for.
