While the Garmin Nuvi 350 may have received over a thousand five star reviews all over the internet, it's still got plenty of problems. Not every GPS is right for every person. While I'm sure you can find plenty of reviews on how great the Garmin Nuvi 350 is, let's just take a second and honestly highlight some of the major flaws with this unit.
First and foremost, if your reason for using a GPS does not include a car, then stop reading right now, and start looking for a different GPS. The Nuvi 350 is primarily meant for navigating in an automobile. That's not to say you can't take it on a hike with you. It does have a built in battery. It's just there are other GPS units designed specifically for non-automobile travelling such as sailing, hiking, or motorcycling.
The built-in lithium ion battery is not user serviceable. Meaning, that when the battery dies a few years down the road (no pun intended), you'll have to ship it off to Garmin and have them replace the battery. As if the inconvenience of not having your GPS while it is being "serviced" (10-14 days) is bad enough, it will cost you about $80 plus shipping to have Garmin do the work. Extremely inconvenient, but not as expensive as it used to be. When the Nuvi 350 first came out Garmin was charging about $250 to replace the battery. While you may luck out, and get an original battery that lasts longer than the GPS, it's a bit of a crap shoot. Of course, if your the type that doesn't mind ignoring "do not open" manufacturer labels, you can probably find a 3rd party replacement battery, and do the work your self.
Based on the customer feedback I've heard, about 1 in 10 Nuvi users have some sort of major navigational problem while navigating with their Nuvi 350. That includes, sending users in the wrong direction, picking a route that is not the quickest one, losing satellite signal during a critical navigation point of a journey, or simply not being able recalculate a new route in a timely fashion. While navigation failure is not always the fault of the GPS, the smart consumer should keep a few points in mind when setting their expectations as to what the Nuvi 350 is capable of. While navigational software has come a long way, it's no where near as good as it will be in a few more years. In other words, there's plenty of room for improvement. Things change a lot. New roads, subdivisions, bridges, shopping plazas, office buildings, points of interest etc etc etc. A GPS unit like the Nuvi 350 is only as good as it's database. It's an enormous job to keep track of all that.
As a side note, there is one practice that could potentially save you a lot of grief as a GPS user. I'm a part time sailor, and a big fan of GPS devices. I use one extensively when I go sailing on long trips. But, I would never dream of sailing any significant distance without proper paper maps / charts. I don't care how many bells and whistles your brand spanking new GPS has. It's probably going to fail at some point. Always carry a paper map of any unfamiliar areas you may be travelling to. Don't rely 100% on your Garmin Nuvi or any GPS to tell you where you are, or how to get somewhere else. It's just common sense.
If you've read this far, I obviously haven't scared you off from using a Garmin Nuvi 350. At the very least, you should consider some other nice GPS navigators. It's always good to be informed, and have a few choices for comparison. It's the best way to make an educated decision.
