Time doesn't matter as long as you eventually get the whole update ok. Some of the map updates are very large and will be slow on a slower connection, plus there may be others downloading at the same time.Time doesn't matter as long as you eventually get the whole update ok.As it also offers a load for US and Canada, there must be capacity to add Canada without removing USA. No, I didn't ask on my own forum as when these types of Qs arise, the advice is usually spotty and this IS the gadgets forum! You'll need to download the map data before you leave home.But I would do a test with a Canadian address to see if it doesn't already have Canada. I know how to use my cell phone for directions at home, where roaming costs are not an issue. At least for Android you can down load a free trial version and see if you like it at home. Personally I'm not a big fan of the routing but it basically works.
Some of the map updates are very large and will be slow on a slower connection, plus there may be others downloading at the same time.For those with newer devices these changes have made it much simpler, for others it can still be a painful process with numerous calls to Garmin technical support.Even with several years of updating various models of Garmin sat-navs, I have found the experience torturous at times.We own a 3 year old USA model Garmin Nuvi 50 with USA maps only. Please can somebody let me know if it is possible to load maps for Canada onto the device? I have looked at Garmin's website, and most of the links are for updating existing map sets.IIt seems to have few comments on loading maps for different geographic areas and whether it would be possible.
