Problems updating USA and Europe maps for garmin 1370T

Hi Garmin21

Micro SD Cards will work with your unit, any size in GB will be recognized, the only thing you will need to do once you have placed your maps on the Micro SD card is to obtain the SD Card serial number, you can obtain this by holding your finger over the battery symbol on the Gsarmin unit for 10 seconds and the maintenance pages will appear, scroll right using the arrows and get to the page for Mass storage card, the serial number will be 6 digits long for a micro SD Card and 10 long for an SD Card (make a note of these numbers) If holding the Battery symbol does not work then try the time (some unit act slightly differently)
Now that you have this info you will need to find yourself a copy of Garmin Keygen.exe, do a google search for "JMKG 1.5 Final" and that should find it.
Using this program, put the Micro SD Card serial number into the top line, where it says enter unit ID, hit generate and copy the long serial number that was generated into notepad on your PC, now save that file with the name sw.unl and save the type as "all files", intially save it to your desktop.
Now load your maps to the Micro SD card, they should load to a directory called Garmin, once the maps are on the card, you can then copy or move the file sw.unl into the Garmin directory on your micro SD card.
If you have a JCV file as well, create a folder called JCV inside the Garmin folder and copy the .JCV file there, this will keep space free on the GPS unit.
Additionlly you might also have the GMAP3D.img file for the same map, rename this GMAP3D1.img and copy to the Garmin directory on the micro SD card.
You will find that the mapser you have put onto the micro SD card will e named gmapsupp.img, this is fine, but if at a later date you add more maps to the micro SD card yu will need to alter the title of the new maps to mapsupp1.img and next gmapsupp2.img etc.
Sounds a long procedure but in actual fact only takes minutes to do.

As and example I have just configured a friends new Garmin Nuvi 50LM with City Nav North America 2012.20, City Nav Europe 2012.20, Topo UK and Top Europe and all of these file with the 3D maps and Junction view files are on an 8GB Micro SD Card, thereby leaving the original 2012.10 maps switched off on the Garmin unit..

Once you have completed all this, with the Garmin powered up and unplugged from the PC, select Settings, Map, Info and you will see all the maps that are loaded onto both the device and the Micro SD Card, it is here that you can select or delect a map, note that changing this does NOT delete the maps, just stops the unit reading them when it powers up, can be reselected at any time.....

Hope the info helps
Regards
Kevin

Kevin,

1. We do NOT discuss pirating maps here.

2. Your information is almost completely wrong. If Garmin21 is running into a space limitation he needs nothing more than a MicroSD card to put the maps on (recommended: 4GB), and a copy of MapInstall, which he should have on his computer already.

Garmin21, you want a MicroSD and a copy of MapInstall. MapInstall has the option of copying maps to the SD Card so you're good there. Kevin's method wouldn't work because of GMA authentication embedded in the maps specifically because of guys like Kevin.

Search the forums. There is a post or two that explains exactly how to do the process. If you get stuck, we regular members will help you out, and do it legally.

Hi Kevin,

Thank you for the advice, even if what rvusa adviced was legal the steps and technicality is way over my head. I wont have done it anyway. I have heard horrible stories of people reconfiguring their electronics the wrong way and messing things up.I dont want to run the risk of doing that which I know would happen if I tried.

I want to buy thee micro sd card on amazon..I only see micro SD HC. will that work. I also read that anything over 16GB does not work.

I am thinking of just buying the nu maps lifetime updates for both the USA and Europe maps. Will that solve the problem. I would think I wont need space for that right? Or would I see need a micro SD card.

One last silly question..Where do find Mapinstall to download? Thanks you so much and I look forward to your reply

Kind regards,

Garmin21

Hi kevin,

Thank you very much for taking the time to go into detail of resolving my problem..Seems I am not a techi kinda person, I wont even wanna attempt to do what you mentioned for the fear of blowing up my GPS. Thanks again for your response and have a great week

kind regards

@Garmin21: My name is not Kevin. I was replying to rvusa, who happens to sign his posts as "Kevin". The confusion is understandable, so don't worry too much about it.

Now, what Kevin's procedure would have done, if Garmin hadn't implemented digital rights management into the maps, is allow you to move the map from one device to another since the maps would be tied to the MicroSD card rather than the device. Maps from Garmin can legally only be installed to one device: the GPS receiver.

I posted that just to explain what Kevin was trying to do. I also know he missed at least one step if not more in the process, but that's not a matter for discussion. What is relevant are your questions, so with the preliminaries out of the way...

It's very difficult to "brick" (permanently render unusable) a GPS receiver. When it comes to upgrading maps the only real way to brick the GPS receiver is by unplugging the receiver from the computer while in the middle of a map update. Map updates are very safe. It is prudent however to take precautions.

The most important precaution before you do ANY work on a GPS is to back it up by copying all the information from the receiver to a directory on your hard drive, in case you do run into difficulty. Assuming you are running Windows 7, you will need to make sure hidden files are visible. Follow these steps from Microsoft. Make sure the file extensions are visible. Once the files and extensions are visible, make a new folder on your hard drive (e.g. C:\1370T) and copy all the files from the receiver to the directory (Microsoft help here).

Ignore the embedded links if you already know how to do this kind of thing.

You will need to delete the unused voices from your GPS to make room for the North America map. Delete all voices except for the voice you like best. Once you do that, you're ready to install the maps.

Get a MicroSD card in any size up to 16GB for your 1370T. All of them, from 4GB on up are HC (High Capacity), so I would simply grab the largest one you can afford. Where you are planning on installing North America AND Europe, get at least an 8GB card instead of the 4GB I recommended earlier. Create the following folders on the MicroSD card:

X:\Garmin\JCV
X:\Map

We here at POI Factory generally recommend lifetime map updates over one-time maps because in the long run they are less expensive than the one-time option. So while lifetime map updates will not solve memory problems (that's what the MicroSD card is for) it will ensure you have the latest map whenever you need it. You do not absolutely need to update the maps every quarter like many of us do, but I recommend doing so, simply so that you can become familiar with the process.

Run Garmin's map updater program. At some point in the process you should have an "Options" button pop up. Tap on that and check "Install Maps to Computer Only" and let the program run. It will download the maps and store them in a directory (C:\ProgramData\GARMIN\Maps).

Download Garmin BaseCamp from Garmin's site (direct link here) and install it. BaseCamp will give you the map management tools you need to do the next steps, including MapInstall. MapInstall is required to install maps to the MicroSD card since the Garmin automated map installer does not see the MicroSD card, due to shortsightedness on Garmin's part.

Once you have BaseCamp installed, plug in your GPS to the computer if it isn't already pluggeed in. Find MapInstall, which will be in the Garmin directory on the Start Menu and run it. MapInstall has a welcome screen. Click next to be taken to the Device Settings screen. Your GPS should show up in the device drop-down box. If it doesn't, click "Find Device".

For the next steps I am going to assume that you are installing the North America map to the internal memory and the Europe map to the MicroSD card. The procedure is going to be the same for both sets of maps, but you need to ensure that the device is selected for North America, and the memory card slot is selected for Europe. This means you will need to run the MapInstall program twice: once for North America and once for Europe.

Tap "Next". The next screen shows a map of North America (or Europe). On the lower left of the map screen is a drop-down box. Tap the arrow on the drop-down box and you can select which map to work with. When you run the mouse over sections of the map, they become outlined in yellow. Take your mouse, hold the left button down and drag the mouse from the upper left corner to the lower right so that all the sections of the map are highlighted. Let go of the mouse button and all the sections of the map will change to pink. Tap "Next" on this screen and "Finish" on the subsequent screen. You then can go do something else since the map transfer will take about an hour (two hours or more for Europe).

Once you have finished with the maps, you need to find the JCV files. These are junction view files and should have been downloaded along with the maps. They will have an extension of .JCV. Copy the files into the \Garmin\JCV directory on the MicroSD card.

Unplug the GPS from the computer and let it reboot. You should be ready to go. This is long and detailed, however I broke it down into small chunks that should be easy to digest. Quite honestly, I spent more time typing this out than actually doing it, as this video shows.

Thank you very much for your indepth breakdown of solving my problem. Hopefully my unit does not go up in smoke when i set out on this adventure..My apologies for calling you Kevin.

Kind regards,

Garmin21

Good luck to you, and there's no need to apologize. I wasn't offended, and I'm glad I could help.
