Using the route function

I can’t get the route process to work properly….to start a route I click on the route icon and select current position…..no problems…..but then when I click on the icon again to anter my destination and if I choose address option and enter the street , number and city ….the routing process begins and then makes a route for about 500m from my current location instead of to the entered destination…..the only way I can get the route function to work is by adding a PIN as the destination ……can you please help me
