Am having a problem specifying one or two digit highway numbers when using the Junction function (Nuvi 2450LM, s/w 3.30, 2013 NA maps). Three digit highway numbers are usually found but if only one or two digits, all that is found is street numbers. An example would be the junction between highway 1 and highway 9 in Alberta, Canada. The proper highway numbers are indicated on the maps BTW.
Any help in how to enter these highways would be appreciated.
