Summary: Excellent display and lots of useful features. Several major issues. Frequent navigation errors - the unit often chooses a clearly suboptimal route, especially in urban areas. Trouble finding satellites on mountain roads - a lot more trouble than my old Garmin had.
Summary: DO NOT BUY THIS GARMIN GPS! We bought this very expensive Garmin GPS at Best Buy 4 months ago. Within two (2) months the LED screen underneath the glass screen cracked and the unit was no longer usable. We did not drop it or do anything abnormal just one day it was cracked.
Summary: This is the worst GPS I have ever owned. I have had it less than 6 months. The directions are not appropriate. It constantly directs you through the dead center of town in the rush hour rather than around the loop.
Summary: Bought this as a gift for my father. It stopped working after 3 years of (very) light use. Unfortunately, the warranty is only for 1 year. Garmin's flat rate repair fee for this GPS is $150. Meanwhile, my Magellan GPS which I purchased in 2008 is still working.
Summary: I bought this product based on the CNET review but I've been extremely disappointed. When it works, it is great, but it only works about 60% of the time. I live in the SF Bay Area. It got lost in SF and I had to drive around until it could figure out where it was.
Garmin GPS dissappointment - Don't spend your money on this!

Summary: I used to own a Magellan 860 which I loved - it gave me turn by turn directions, lane assist and the option of chosing routes. This GPS - does not provide turn by turn, I cannot chose routes - many times it has taken me the long way around, for lane assist it is not always specific.
Summary: I have had a Nuvi 1690 for a couple of years. My daughter was going away to college so I gave it to her and purchased a new 3490 for myself. What a disappointment. Most of the features that I enjoyed on my 1690 don't exist on the 3490.
Summary: This is a horrible device. I used Garmin's products for years and i never had a problem. Either their software or their maps are faulty. It seems to me that Garmin is trying to create a fancy device and yet they are creating unreliable trash.
Useless if you live or go through the Washington DC area

Summary: This device will not calculate any route that goes through the intersection of I-495(Capital Beltway) and Route 267(the Dulles Toll Road)outside the Washington, DC area. That intersection is missing from the maps.
