When we set out to do a top ten from Amazon, we were surprised to find that Garmin Nüvi had pretty well taken over the market. Out of the top 20 bestselling GPS on Amazon, only 5 of them were not Garmin devices (four TomTom and one Magellan). And out of the 15 Garmin devices, only one of them was not from the Nüvi line (Garmin Dezl 760LMT, ranked 16).
The Nüvi line is very popular and we have written several articles dissecting the Nüvi line and comparing them in a chart for your convenience. The Nüvi line all have voice guided navigation, lane assist, turn-by-turn instructions and a bright, friendly screen. All devices with LM after the model number come with free lifetime maps. When purchased on Amazon, many of these units also include a mount for your windshield or dashboard.
