Sorry if this is the wrong place for this, but it was the best I could find.
Nuvi 2797
Insists on announcing streets and roads with a descriptive name instead of the route number. For example "Lincoln Highway" instead of "route 30" or "William Penn Highway" instead of "route 22".
Lincoln Highway is not a problem, but most of the other names are lost in antiquity from before there way a highway numbering system.
Is there any way to change this behavior on my Nuvi 2797?
