Ive always used Tom Tom that comes in standard when I rent a car from Europcar. Pretty decent in most urban areas I would say. It might let you down if u r looking for an obscure street in the outskirts.
My major problem with it is how to correctly key in "Aleja Jana Pawla", Warsaw.
As you may expect, there is about 6 of 7 "Jana Pawla" streets or whatever in Warsaw, and for some reason, I always end up in a backwater Jana pawla street 10 miles away from the center, instead of the big boulevard parallel to Marszalkowska.
