Not sure about source maps...but everyone I talk to says Garmin is the best. Lifetime map updates for $80. - Just another Bubba

I would marry my garmin if I could, and just got the lifetimes updates. - ωαřмaiden ❤Bassetmom❤

I have a Garmin Nuvi 265w and like it so in the end Garmin might be best but others I know have Tom Tom and swear by it. - Brian Sullivan

So the maps are from different sources so I am back to trying to decide about quality of maps in the Whitehorse and the Yukon. - Brian Sullivan

He is a planning on driving and at least spending the summer there (and perhaps a whole year if he can find a teaching job). But I am guessing that hiking/canoeing are on the agenda as well -- both he and his girlfriend spent years as camp/tripping staff. - Brian Sullivan

Yeah -- from what I can tell that is true -- my Garmin has a walking and biking mode so it can be used in urban walking and biking situations but is mainly a car GPS. I was thinking a car GPS would be my contribution. I wouldn't presume to get a canoeing/hiking device for him -- he probably knows more about it than I. - Brian Sullivan

As someone pointed out earlier Garmin updates are now available at 60-90 lifetime. I have never updated my Garmin and for my purposes anyway it hasn't been an issue. - Brian Sullivan

I agree things change - and occasionally I find myself out in the weeds when on streets not on my older maps but like I said it hasn't been a real issue up 'til now. I might consider an update next year some time. - Brian Sullivan

Well the service is an issue (and Google maps may be updated to your device on the fly but is still often way out of date) -- besides the cost of the device, the service. I suspect if you do a cost analysis it is way cheaper to use a single purpose GPS device. - Brian Sullivan

Well Google maps occasionally being sadly out of date is a fact (Bing in many cases is better). The cost analysis I guess is arguable. - Brian Sullivan
