Why doesn’t my Garmin StreetPilot c550 recognize “Route” numbers as streets?
I keep trying to add locations into my Streetpilot c550, and if they place I want to add is on a “route,” the Garmin doesn’t recognize the street name… I don’t know the proper street names for a lot of Route’s near my house…how do I fix this?
My address is on State Route V. My Garmin won’t accept that either. I have to enter “Highway” instead of “Route”. Hope this helps.
