I am going to Mongolia in about a month for a backpacking trip and I didn't wanna get charged up the butt to use Google Maps on my Blackberry, I searched for a way to use GPS without a data connection. This program works 100%, tried it last night and love it. Now I don't have to have a data connection to use GPS on my phone. All the maps are downloaded on my MicroSD Card.

Here's another way to get free GPS without a data plan. (This will only work if your phone has a built in GPS module)

Here are the step-by-step instructions for MGMaps on your Blackberry.

OK, here's what to do

On your Blackberry

1) Put in your MicroSD card
2) Connect your Blackberry to your computer via USB cable
3) When the window comes up asking you whether to enable Mass Storage, say YES

On your computer

1) Make sure you can see your SD card (it will be listed as a removable disk drive)
2) Go over to Map Creation Tool (http://www.mapcacher.com/) for MGMaps and follow the instructions to outline your custom map, I would recommend going from 0-16 (zoom levels), and SLOW and DETAILED level of detail
3) Save your custom map on a desktop or somewhere where you can see it, but becareful to save it as ".map" extension within the quotation marks, and select All Files from the Save File As drop-box. (For example, I chose "Mongolia.map")
4) Next click the link to download and install GMAP Maker www.mgmaps.com/cache/gMapMaker-setup.exe
5) After installation, open GMapmaker, and press GO -> it will ask you for that Mongolia.map file you saved in Step 3
6) Wait for the download to finish (this will take a long time)
7) When everything is said and done, copy the MGMapsCache folder (located probably at C:/ProgramFiles/GMapMaker/) to your SD card
8) Install the signed version of MGMaps Index of /projects/mgmaps/Blackberry (http://www.iroot.ca/projects/mgmaps/Blackberry) using Windows Desktop Manager

Back on the Blackberry

- Open up MGMaps, go to Settings - Maps - Stored Maps - and select Offline Mode and Stored Maps

There you go, now you can track your position for free, anywhere, free of charge. Enjoy :bounce:

If you have both Google Maps and MGMaps installed on your Blackberry. When you try and start up Google Maps, it will erase Mobile GMaps.

To fix the issue, on your Blackberry:

Go into the permissions for google maps under advanced settings and set "Module Management" to "Deny"

Made changes above

Excellent. I do have the unlimited data plan, but in foreign countries, I know from experience that data usage can get very expensive. I'll keep this in mind for next time.

Does this work no matter what your cellphone plan is? Verizon disables things, especially if it is a GPS application. It's not an issue for me because I don't travel out of the country so using data, unlimited, is ok. I just wondered if this works for Verizon.

On your Blackberry, go to options, advanced options, gps, click menu, refresh GPS. If you see coordinates after a couple of mins, this app will work! Not just true for Verzion, any Blackberry/Provider Worldwide. Don't believe me, take out your sim and refresh gps. You will see it!

Models I know of that have built in GPS Module include:

8110, 8130, 8800, 8820, 8830, 8310, 8330, 9000, 8900, not sure about storm.
