I received my Tom Tom GO COMFORT yesterday, 02 APR 2020. After setting it up I noticed I only had a map of the USA Canada & Mexico. I bought this make / model under the impression i could get the "World" maps but that does not appear to be the case. I've tried adding another map but only received the message "Available space 6,71GB". Do I have the wrong Tom Tom model to use with "World" maps?
