Summary: GPS is great. Glad it came with lifetime map updates, however, don't expect to put new map updates on the internal memory of your new GPS as there is not enough space. You may want to buy a microSD card if you plan on updating the maps. I gave it 3 stars only because I was expecting to be able to update the maps without having to buy additional hardware.
Summary: If the GPS is on the car charger, it will ask you if you want to turn it off when you turn off the ignition at a gas station. If you choose "yes", you will lose the audio guidance when you start the unit back up.
Pros: When it works, it's a pretty decent GPS. See my previous review.
Cons: Reboots frequently on long trips. On one leg from Ft. Worth to Albuquerque it rebooted on me every 1/2 hour or so. It resumes navigation when it comes back up, but it drops the connection to the EcorouteHD gadget. The reboots may be related to the topo maps it puts up when it zooms out automatically on long legs; sometimes you see topo tiles paging in and out before it crashes. Can you say memory leak? Frequent firmware updates seem to fix some problems but introduce ...
Not real happy and will be requesting a replacement unit after the trip is
6 July 2011
Summary: I baught this unit for a major vacation trip around the Untied States western area. Two weeks into the trip it seized up and would not work. Error message said no data loaded for maps. I loaded the complete new update which took over 4 hours at a McDonalds wi-fi hot spot. It can not find a lot of POI's that my four year old garmin can with older updates that are no longer supported.
Summary: I purchased this product for several key features that do not appear to deliver as advertised. I have used this GPS for several trips so far, including a trip from Minneapolis to Chicago. 1) The power cord is very thick, 2X my old Garmin, supposedly because the traffic module antenna is embedded into the cord. This makes the cord very stiff & bulky to store in the glovebox.
Summary: I got this GPS from another store. Out of the box I noticed it had two stuck pixels. This might be not a big deal but it is very visible when driving at night and is kind of annoying. The more important issue that just struck me is popup ads on the screen. Every time you start driving you see them. They can pop up even when you stop on the red light.
Summary: 12/10/2010 Addendum: Alert - I bought a second nuvi 1390LMT and that one started giving me pop-up warnings after it turned on. Two different pop-ups were observed. 1. "This accessory is not supported" 2. "XM is not supported." Upon closer inspection, I noticed that the USB power plug and USB plug receptacle on the nuvi were severely corroded. They had come that way from the factory and I had not noticed the defect during installation.
Summary: Followed the instructions upon receipt of the unit (Garmin Nuvi 1390LMT), I took the device outside to get it to locate the satalites. I then plugged into my computer and followed the instrcutions on [...] The process is very easy to follow. The full North American maps cannot be downloaded onto the divice without an additional memory card.
Garmin 1390LMT: Lifetime Maps but limited memory and difficult process to install updates
29 May 2011
Summary: Garmin 1390LMT comes with great features and is very intuitive to register, set-up and use. I purchased primarily for my trip to Boston and it worked but it's not without it's quirks. At the time of purchase, I felt extra features such as Lane Assist, traffic and Life Time Map updates were worth the extra money. Lane assist flashes a picture of the lane you should be in during your journey. It's quite handy when driving unfamiliar roads by keeping you on course.
Summary: This unit is indistinguishable from a brand new one, but the map supplied (in April 2011) is version 2011.10 which was first released in early 2010 (don't you just love Garmin's numbering - obviously learn't from magazine publishers!?). The current map is 2011.40. Whilst there a a "Numap" guarantee of one free update, why should I use this to get an up-to-date product? Probably will wait till 2012.10 is released, hopefully within the 60 day guarantee period.
