Let me start by saying that I’m a gadget guy and work as a service manager. As it is 7 months since I first reviewed the unit and I like it even more now I wrote this for the 1450 page before the 1450LMT was shown on-line so I’m reposing this here. If you're not comfortable tinkering with stuff like this look for a unit that has more internal memory.
#GARMIN MAPSOURCE UPDATE FULL#
Do a full backup of the unit before you start messing with it just to be safe. Turn to the web as there are many great sources to walk you through these minor issues. This information is unfortunately not spelled out in any of Garmin's literature.
#GARMIN MAPSOURCE UPDATE HOW TO#
Do a search for "Nuvi JCV file" and you'll find instructions on how to do this. The best option I found was to put all the maps on the internal memory, disable the tiny Junction View file on the GPS, and download the complete Junction View file directly from Garmin to the memory card.
You can load a portion of the maps, say the lower 48 states, to the internal memory and the rest to the micro SD card. With a micro SD card this really becomes a non-issue. Sadly I bet many people have traveled with units like this and wondered why the Junction View didn't work. The trouble with this limited file is there is no way to know what you don't have until you need it. What does this mean? While traveling on the interstate you won't get lane change images for every exit. What is a nearly 750 mb file as a direct download from Garmin is crushed to around 50 mb by the auto updater. What I learned by trial, error, scouring the web, and a little careful messing around is that the Junction View file is severely edited by the auto-update. This will give you useful options for changing how maps are loaded on the gps later. When you first run the Lifetime Updater look in the settings for downloading the maps to BOTH the gps and computer.
#GARMIN MAPSOURCE UPDATE UPDATE#
If you use Garmin's Lifetime Updater to automatically update your maps it won't explain what your not getting to squeeze the maps onto the internal memory of the device. not including the other data that most people enjoy like Junction View (the lane changing images for the interstates). The latest release of City Nav NA is almost 1.56 Gb by itself. This becomes important as the newer mapsets like City Navigator North America are getting really large.
This unit, like many others of this "age", has 2 Gb of internal memory. These "older" models are going on sale as newer units with more features, and more importantly internal memory, are on the market. It's a twin to the 1490 minus the Bluetooth capability. This GPS is a solid performer and still a decent value if you can find it on sale.
