 https://historum.com/threads/pre-greek-hydronyms.140990/

has sought the pre-Greek toponyms and found many hydronyms with the small word/suffix VrnV (V for vocal). I myself have found in the Book of Isaac Taylor the river ARNO and his could belong to this category. 

But slowly. Firstly I give the word the other blogger Midas

who wrote about these hydronyms. 

He wrote that he found several hydronyms that are probably of Pre-Greek origin.

His list:

*

Arna, Andros
Name of a village, rich in springs.

Arna, Laconia
Village and the name of a cave-spring nearby.

Arnaea, Chalkidike
A small town full of water. Not very far away, a Greek brand of bottled water is produced.

Arnissa, Pella
The -ssa ending is a typical in pre-Greek toponyms. Arnissa was and still is a city in the shores of Lake Begoritida, western Makedonia.

Arnitha, Rhodos
A Mycenaean village, surviving until today. There're two springs there, being the second largest watersource of the island.

Aroanios
Small river in Achaea.

Bourina
Name of a spring in Kalymnos

Phalasarna
Ancient harbour town in Crete, rich in water. Excavations have revealed ancient wells and water tanks.

Alassarna, Kos
Name following the same fashion as Phalasarna. Kos is rich in water anyway, so no conclusion can be made, other than the similarity of the two toponyms. Alassa, is also a spring in Andros and a water dam in Cyprus. 

Myrina, Lemnos
A small town in Lemnos, rich in ancient remains that were full of wells and that date back to 4000 B.C. Rich in drinking water, even today.

Aruna is a sea god in Hittite mythology and the Hittite City Arinna mens the Source (German Quelle)

And 

Arno is a river in Etruria.

Now I suppose, I figured it out with the help of Isaac Taylor:

The Turkish word ARNA, meaning the water channel or water course could be the etymological explanation. When we accept, the Etruscan are from Anatolia, then it is not a surprise.
