In choosing this year's Mother's Day picks, I focused on ease of use, routing quality (the path the GPS chooses to get from A to B), GPS sensitivity, and favored the larger wide-screen displays as well as text-to-speech to ease navigation (all the GPS units listed here will speak actual street names instead of generic turn instructions).

		If money is no object, Garmin's nuvi 780 displays the kind of refinement, reliability, and ease of use that comes from years of testing and fine-tuning. The bright, 4.3" widescreen display is easy to read, and text is large enough to be seen from the driver's seat. The nuvi 780 sells online for $480.
		Garmin's nuvi 660 was my Editor's Choice GPS last year (when it sold for almost $1,000), and is still the GPS I use in my car today. It currently sells for around $340 online. The nuvi 660 doesn't have all the features of the newer nuvi 780, but has the same bright widescreen display, ease of use, and navigates identically to the nuvi 780. Plus, the 660 includes everything you need to get real-time traffic data, has a built-in FM transmitter for listening to music, and a host of other handy features. If you don't care about traffic data, the nuvi 650 is also a good buy at around $300.
		Magellan's Maestro 4250 sells for around $290, and includes real-time traffic as well as the ability to operate the GPS using voice commands. Though not quite as refined as Garmin's units, the Maestro 4250 is a competitent navigator. Unfortunately, Magellan's customer support has declined in recent years to new lows, so keep your fingers crossed you won't need to call customer support..
		At around $250, TomTom's ONE XL-S is the least expensive wide-screen GPS that includes text-to-speech (it speaks actual street names) in this round-up. TomTom's GPS units aren't quite as good at picking the best routes as Garmin or Magellan, but owners love their good looks and unique features.
