I love my GPS unit (truly, madly, deeply), but the truth of the matter is that your GPS is only as good as the maps on it. And while I think Garmin makes very nice GPS units, I also think they kind of stick it to you with the price of their map upgrades. And if you live in an area where they’re constantly working on the roads, it doesn’t take long before your GPS thinks you’re driving in the river when you’re really not. (Not that it’s not amusing, now and again, to listen to it plead with you “Please return to the road.”)
With this in mind, I’m inclined to call this one a smokin’ deal: Amazon currently has the TomTom XL 350TM 4.3-Inch GPS for just $130, and that includes lifetime traffic and map updates. [Edited to add: Looks like it’s now defaulting to a different vendor on the Amazon page. Look for the “More Buying Choices” column on the right and choose to see the price in-cart when buying directly from Amazon, to get the $130 price.] You’ll never need another unit, unless the new ones start doing something really cool like autopilot, or something.
Or maybe laser shows. Laser shows would be cool, too. But barring that? This is the unit to have. No matter how many times they rip up and move the roads.
