Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
(I regret that I am not able to offer Live Phone Call service at this time; However, your request is still open to other Experts in this category, and one of them may pick up on it at any time.)
I would advise you to first of all make sure that you installed the Canadian map file correctly, validly, and with authorization for its use, onto the Garmin device.
How did you do the install of the map file, or try to, and what was the result, please? with this information, I could advise you.
Please use the Reply To Expert function to let me know. Thanks.
