Summary: Flakey routing & screen too small. Extremely expensive for what you get. "Permanent" mounting bracket is fiddly ( with a tiny screw that is easy to lose, which secures the power cable to the bracket) with no included weather cover for the contacts which are exposed when the unit is removed and provided RAM mounting hardware is bulky. I've been using Garmin products for many years, but this seems way overpriced for whatever, alleged, durability might be present.
Summary: I'm on my second 350LM and it doesn't work either. The first one I purchased through an Amazon retailer suffered from freeze-up issues while in navigation mode. While either soft or hard resets got it working again, the problem recurred. Garmin's CS (after very very long hold time) said the only issue this could be was from corrupt software.
Summary: Much more difficult to use than my first garmin. Search is hard to do by state or even city within a state. Battery life is short, especially when brightness is turned up to allow daytime use on the motorcycle. Weather protection is a plus but you could buy three and drown the first two and still come out ahead.
Summary: I'm happy with the features of this unit, the mounting options, and its apparent ruggedness. The touch screen also works well with gloves. However, the bluetooth functionality is inadequate. I have the machine paired with a Sena smh10, which is also paired with a smartphone. There are two things I would like to see Garmin fix with a software update. Both problems arise when listening to music.
Summary: Even at 100% brightness, the display is very hard to see in bright sunlight, and will wash out completely when the sun is at particular angles. I've tried a variety of different mounting angles to no avail. At less than 100% brightness, it's impossible to see in daylight at all. Worse, at 100% brightness when you ride into a shady area the display becomes a giant light shining in your face.
Summary: I have had a Garmin Nuvi for years and have been extremely happy with it. My wife and I recently purchased motorcycles so we decided to pickup the Zumo to track our country drives. Additionally she got the Nuvi and I now port the Zumo between the bike and my truck. I drive a lot for work. Luckily I know where I'm going or I may still be driving to the first destination I plugged into the Zumo. The routes are absolutely terrible.
Summary: The mounting hardware in my kit would not attach the mount to 1" handlebars, which I think are standard. the screws used to attach to the clutch/brake clamp and the U-bolt were all about 1/2" short. I emailed Garmin and here is the response I got: Dear Dennis, Thank you for contacting Garmin International. It will be my pleasure to assist you with this. I am sorry to hear about the trouble you are experiencing with the mount for your device.
Map overhead view infuriating to use and ad-hoc route changes are far harder than 550
Barry Kelly, Amazon

Summary: I used to own a Zumo 550. Not long ago, it tumbled out of its mount and got squished under a car. I put about 35k on its odometer, in both Europe and the US, so I knew it well. The 350 is wider but shallower than the 550, and about the same weight, perhaps slightly lighter. The battery is not removable, but it does last longer, and the voice synthesis works without hardwired power. The mount is a bit better, I will tentatively say.
Summary: Although mechanically very nice, including the mounting, I cannot recommend this SatNav. I used it one week and returned it because it crashed four times. Each time when it was really needed - when calculating a route after a wrong turn or road works. And when it crashed it left the screen unchanged so it took a while to find out. I then had to hold the power button 5s, sometimes more than once, then wait for a reboot before continuing.
Device so far unreliable - Freezes randomly - Poor customer service
Marc Dubresson, Amazon

Summary: So far the Zumo 350 has proven unreliable. How can you trust it on any journey when it freezes randomly? Reseting, updating...etc to no avail, support has been slow and unhelpful so far. Many forums are relating the same issue over the world but so far Garmin does not see fit to respond/acknowledge and the customer is left to do their quality assurance.
