Thank you all for your good suggestions, but after some scratching of my head and some experiments, I found out that the porblem was more bureaucratict than technical. I try to make a summary of the key issues of the process.
First, there was some kind of omitment of the dealer to allow my access to the maps, it was opened aften he returned from his Xmas holidays, but that was not enough for me to get into the process of loading the maps.
The Leapmotor T03 APP was needed for the BINDing of the "intellectual" connection. The APP is available in Google PlayStore, for free. The APP has an restricted distribution according to geographical areas, where Leapmotor T03 is sold.
My first attemps to load the Leapmotor T03 APP failed to a message: Not available in your AREA. I tried to be smart and used an VPN setting my location to be: 1) Spain, 2) Germany and 3) UK, but the resulta was the same: Not available in your AREA.
I tried to be a bit smarter: I had a phone with two SIM cards, one Finnish and one Spanish. So I disabled the Finnish SIM card and was hoping that my request for the APP would now come from Spain. I had bought the car from Sevilla, Spain, so according to my logic, Spain would be a proper geographical area. The response was still the same: Not available in your AREA.
I suspected that there was something in my phone, as it was initialized in Finland, that was smelling nonSpanish, so I took an older Smartphone reser it to the factory settings and tried again, now there was a change in the tone: No Spanish Credit card. The Google PlayStore is not using national borders or even EU economical cooperating areas, according to them the BANKS define our location on the map. I had only Finnish credit cards so I had to get one Spanish, that was no big problem, but a bit unnecessary in my mind.
Now I had a "pure" Spanish phone, Spanish loacation, I was in Benalmadena, Andalucia, Spain and I had a Spanish credit card and now I did not get any more complaints of the AREA, but the result was still unsatisfactory: This APP will not work in your phone.
So what now? A friendly PC wendor and consult, sold me a Chinese smartphone for 105 euros, initialized without any of my interference, so that the phone did not have any smell of the Finnish owner, the Google account had a Spanish credit card and a Spanish addres and believe me or not, the Leapmotor T03 APP was able to read the QR code and opened the way to the coveted maps.
There was lots of maps available, even Finland was on the list, if we for some reason drive this car to Finland. On the way we of course would need maps of France, Germany, perhaps Sweden depending of the route, but now we were happy with the maps of Spain. So let us load the maps of Spain! Time went but nothing happened. This gave me time to think; Spain is actually quite a big area, perhaps there is an option to load a smaller part of Spain and a bit more careful look at the screen told me that there were opitions like the Islands and Andalucia and..so I decided to load the maps of Andalucia, because there is at the moment no plans to go outside Andalucia. It took some time, but the I got the red sign: Apply! and afrer pressing that button, I suddenly could see crooked lines on my previously blank white central screen. I think it took some 20 minutes to load the maps of Andalucia. Looks like the navigator is working as it should.
The Leapmotor T03 has now an own smart phone, and we soon noticed that it has some advantages. After a short test drive we left the car in the parking place and went for coffee and soon we noticed that it is telling us (via the phone) that we had forgotten to lock the doors. Now we have to learn to communicate with the car called Conejito Azul with the telephone.
