Summary: A somewhat greater con is the lack of security. I've decided to lock the device with a PIN but I've noticed that if I just turn on the GPS and let it sit on the PIN input page for a while sometimes it will continue to the main screen without any input. An obvious security issue.
Pros: The main pros are in the specs. Live traffic, map updates etc. I've had it for over a year now and it is still working like the day I first got it. Even better once I figured out how to calibrate the touch screen.
Cons: I rarely use the installed POI database now because the times I have the address is not translated to a correct position on the map, sometimes just a block or two off other times completely inexcusably way off ... like a fifteen minute drive away.
Pros: I've owned this 1390T ~3 years (I don't have the lifetime maps option). It still works just like it did on the 1st day. No problems with power button or touch screen.
Cons: In Pgh where streets are not on a grid pattern, the route is often inefficient, using small neighborhood streets. If you have no idea what you're doing, just follow the garmin and you will always get to your destination eventually. If you have a little knowledge about where you're going (or just look at the garmin map to see what roads look bigger), you can stick to major roads and, when you pass up a turn garmin suggested, it will recalculate your route, often to the...
Pros: Does what it is supposed to. Maps are easy to load, works great for finding restaurants when in different cities, also great for calculating my mileage for work.
Cons: The traffic feature has coupon pop-ups, which is annoying. (And probably not the safest?) Garmin maps/gps are better than any other I've used but occasionally you get to an area where something is different or outdated, but I had similar problems and often much worse with other gps I've used.
Summary: After the 1390LMT was lost in shipment the seller offered a 1350LMT, from what I can tell the only difference is the lack of Bluetooth; no problem as I likely would not have used this feature. So, the Garmin Nuvi 1350LMT is what I received. I have been a Garmin GPS owner for some time and wanted to upgrade my 350 Nuvi with a better map set.
Pros: This gps is very nice, being 18 years old, i'm somewhat new to the highways but i can go pretty much travel anywhere with confidence now. The lanes you need to be in are shown on the gps while on the highway, which is awesome.
Cons: I've noticed that sometimes the lane directions aren't always 100% accurate while on the highway. The only mess up i've found was obvious. I even had my maps updated.
