Searching in Waze 3.0 gives one result in the city Totana (Región de Murcia). I expect Brshk1 did find that location, but I don't think you mean that area!
There are several Avenida Principe de Asturias if you look at
Map24, you get a few results. I think you mean location one. Finding this location in Waze, you come to
this permalink. Some segments have the name you say. But not the whole street. In the whole area is almost nothing labeled with name and city.
There where some problems with this street, I fixed this. I expect after de next map update it is searchable.
at
this point you see a junction with Avenida de Don Juan de Borbón. I replaced the 'problematic rountabout'. But I don't have rights to remove the old junctions, replace new ones. Avenida de Don Juan de Borbón shows paralel streets to the primary street in direction south. This is not what the Aerial shows. So those has to removed...But I don't do that, because of some more rights issues I expect.
But lots of work to do over there! Keep in mind, (re)naming the streets with the same name as yours, gives problems if all get the cityname Murcia. Use Zipcode or district in streetname!
If need any help, please let me know.
***EDIT***
Strange, BRSHK1 reply is dissapeared

And Gerben replied, this was not visible in my 'problematic' TapaTalk...
