Garmin late last year released a new line of compact handheld GPS units, the aera 500 through 560 series. The four new aera units are priced from $875 to $2,199 and key differences between these and the older but still available 196 through 496 series is inclusion of Garmin’s City Navigator NT street mapping system (almost the same as Garmin’s nüvi automotive GPS units) and a touchscreen display.
