Main Menu Weather - How to select default City?

Does anybody know how to change the default city on Main Menu Weather?

I think it’s done under NitoTV, Weather, Add weather location. If you change the zip code, I think it might work. I’m in Canada and it won’t take my postal code so, how do I find my “location ID”?

Here’s the correct way to change it.

Go to Settings. Below “Sleep Now”, you’ll see “custom Settings”. This will take you to “Main Menu Extensions”. From here you get “Main Menu Weather”. Select “search WOEID” to find your location ID. Select it and you’ll be given options to have it displayed on the main menu.  Hope this helps.

Change city is ease. I would like to know how change font size on Main Menu Weather.
