I'd also like that as a Finnish person, since I keep my phone in English, although I imagine I have a slightly easier time parsing them from "English" than you do.

You can change the language of Google Maps to Finnish, and still keep the phone on English. At least in the latest versions of Android. This makes it pronounce the street names properly

At least on Apple devices I found out that the Irish Siri version pronounces Finnish street names the least badly =)
