I am after a GPS or GPS-like device with offline maps for the US and Canada for ~60 or so. I have already tried looking on gumtree/ebay. I've tried Sygic before but it takes so long to lock onto signals :(
I did get a sim card with T Mobile so I can use google maps, but we'll be venturing out into remote national parks, so this may not work so well when not in the cities.
Also something like this https://www.ozbargain.com.au/node/114932 might work too but my knowledge of Nokia phones is a bit limited. Any suggestions on some cheap new/used Nokia phones which do this would help as well.
I'm open to any other ideas.
I'd suggest Navigon for iOS or Android because in the US and Canada the map content matters most, and Garmin is top of the line. Nokia (Navteq) and TomTom are not the market leaders in the US, Garmin and Magellan generally take the top honours.
I'm curious why you want to buy one from here… if you're renting a car there on a trip, they usually offer you a gps from the rental agencies. If you're moving there and are planning to buy a car there, you might as well just buy a GPS unit from Amazon or Best Buy and even Walmart!
