Heloo there,
I too own an Audi A1 with same specs as you,
And the answer is YES and NO!
NO You cant use your laptop to install it.
YES it can be installed by Your local Audi Dealership for a price. (it involves installing the satnav software and inserting an SD card with Audi maps inside it)
I did this because I get lost in my own town. Lol
Well worth the money if you ask me,
Contact Your local Audi Dealer for more information.
They will most likely ask you to bring your car for them to asses.
