Nokia maps on my Symbian was always perfect! But Nuvi is Garmin!

It is pity that after Nuvi 765 the famous Garmin was died If we are lucky and ours Garmin 660, 200-250, 205-265 and 710-765 died too - maybe I will use only Here but I have a doubt about these devices And Symbian devices too I must to drown these kittens but I do not see any reason to sell my soul...
