Picture of Unlock V7 Navigation 1000 GPS
Unlock the Windows CE environment on a V7 Navigation 1000 GPS device.

The V7 1000 is a great, low cost ($300 CAN), and portable GPS. Out of the box, the major features include a MyGuide navigation system, an MP3 Player and a Movie Player (supports DivX).

There are, however, a few quirks with the device. For example: the Time Zone settings do not seem to stick and the "M" button is not very useful. It was searching for a solution to these issues that lead me into my V7 hacking adventure.

Warning: Modifying your V7 1000 in the manner described within this instructable may void your warranty and could permanently damage your device.

Step 1: Overview

The V7 comes with an AC power Adapter, a car power adapter, a suction cup vehicle mount, a CD with manuals and various data files, and a 1GB SD card (loaded with software and maps).

Other than access to a PC and to a SD Card reader, no additional hardware is required. In addition, the modifications presented here do not require any hardware modification. There is already a pretty good tutorial for adding a USB port to the device available here.

This instructable will cover the following steps:

Accessing Windows Explorer
Fixing the M button "bug"
Speeding up "Fly Over" mode
Accessing the Operating System

Much of the information presented here is not my own work. It is a result of collecting info from various sources across the internet, most of which is targeted at similar devices from other manufacturers. The techniques have been adapted to the specific environment of the V7 1000 device and to my personal preferences. The GPSpassion forum is a great resource for more information.

GPS is now widely applied for car, outdoor, fitness, specialty and cell phone, etc. It receives signals from GPS satellites, and the quality of signal is determined by many factors, like solar radiation, atmosphere conditions and terrain. Car DVD GPS

Hi Felllows, Recently bough used V7 Navigation 1000 but later noticed there was no card or any map(s) loaded in the device. Please help me how to resolve this issue, where I can get software etc. Thanks Ron
I can burn you an iso copy of the software CD that came with my 1000 but I need a favour in return - I need the flash folder files that are located in the unit. You can copy the folder onto any 2 or 4 MB SD Card and then zip it and e-mail it to me - once we've established that you can boot your system after you get the iso disk from me. Let me know.

I followed the instructions for most of the fixes but came to a wall in the MyGuide folder as the zip file and probably a couple of others isn't there. I have a V7 1000 and it was 'taken' from my vehicle and when I got it back it wouldn't work. Now it works some but I can't access the navigation panel - doesn't show at all. Where can I go to obtain the flash so I can reload it?

I wonder if this thing has a serial port, you could possibly add bluetooth

I purchased a v7 1000 in August 07. I love the unit. I sent it in in February of 08 and received an upgrade. Recently my battery went bad and I sent it to MygGuide in Santa Clara for a replacement battery. They sent me a new unit that has not been upgraded so my SD card doesn't work. I am getting no help from them at all. When I turn the unit on to navigate I get a message that some of the map files are locked and it won't let me do anything else. Dose anyone know how to fix this problem?

Great Job!!! I tried to load my Brazil.fbl (iGo) map into maps folder, but myguide says the map is locked... anyone knows how to unlock this map and make it work? Thanks a lot!
Hello, I´m trying to find a Brazil.fbl to download, Could you share this file with me? Thanks a lot.
Try to download "Igo" from a torrent web site, they have tons of maps, including Brazil. You will have to download a software to your computer to download torrents first, then look for Igo on "torrentz.com" you'll get many options, it will take a while to download the whole thing but once it is done look for the "maps" folder and you'll see it.

I got to the part, to speed up the fly over bug, and after i pasted the data into the myguide folder, the system shut down. I turned the system back on, and got an error message. The message reads as this. FortunaODMKeyDoor1119 Exeption occured Callstack dumped to \crash.txt if i click ok, it just goes to the myguide background image, and does nothing else. the thing is useless now!!! Anything I can do???
jmills6167 years ago
It looks like after unlocking I might be able to install Igo/MioMap? for example? I really want to add the "text to speech" TTS functionality. Otherwise I'm going to sell it and get a MIO230 with TTS. Any suggestions?
jmills6167 years ago
I just picked up a v7 NAV700. Will this hack work on it? The v7 site has shut down access to updating. Will any of the other GPS maps work? I've found very little mention of the NAV700 anywhere. I guess it's to new or not very popular.

I dont understand this step 6. Can someone help me out.
Great hacks, well explained, nice pics and layout...better explained than the manual that came with the unit! FYI, the MyGuide Navigator 6.1 upgrade is now available and has some nice improvements over the older version. Cheers

I prefer:

Games = "icons/games.bmp", "", 0
Navigate = "", "\\Flash Disk\\myguide\\myguide.exe"
Explorer = "", "\\"

Solitaire= "", "\\Storage Card\\games\\solitaire\\solitaire.exe"
Flux= "", "\\Storage Card\\games\\flux\\flux.exe"
Asia = "", "\\Storage Card\\games\\asia\\asia.exe"
Arvale = "", "\\Storage Card\\games\\arvale\\arvale.exe"

This puts the explorer link on the main screen.
That format doesn't work on the NAV730.
kronx1127 years ago
i try this when i click on explorer and it say: "A system shell must be present to support executing folders paths or shell extensions." this is on device Nav730
V7 Navigation = "icons/V7.bmp", "\\Storage Card\\iGO\\iGOpna.exe"
Explorer= "icons/files.bmp", "\\Windows\\Explorer.exe"

It worked for me. Good luck. Let me know what good things you fine.
hey it works! it load to wince when you did for the 1st time on startup but when you close it and try to go to wince again it won't load wince but load up the explorer. so then I close the explorer but it send me back to the menu screen. then i did a hard boot then it works on 1st run=wince, 2nd=explorer until hard boot. But for me i don't care.........I'm glad it's hack, now i can play my wince games. thanks EdenCrest/dadefatsax (you guys are the BEST!!!!!) i wonder how you know the directory and files in the device? you guys Amazing!!!!

Hi all Can anybody tell me where i can get the sofrware from my dog got hold of my SD card and it won't work and i can't copy it on to a new card. Any help. Regard's Alan.
effigy38 years ago
I was playing around in the SD card files and I note that the voice files contained in the .zip for each language are .ogg files. I'm going to see if I can create a custom voice/language option using Audacity to edit the .ogg files. Has anyone tried this yet?
did it work?

Something extra for the device:
I have the complete command list of IGO below:

I map the M key to FOLLOW_OR_ANNOUNCE, so when I press it, it will tell me the route instruction again.

Also I change the IGOPATH.txt to
[modules]Settings = “icons\settings.bmp”, “settings”, 1Multimedia= “icons\media.bmp”, “Multimedia”, 0Explorer = “icons\files.bmp”, “\\Windows\\Explorer.exe”…..Now explorer will always available in the front, with or without SD.3.More, to change the voice you like, take a look in “Flash Disk\data.zip”. Under “ui\settings” there is a lang.ini file. You can edit it to fit your wayFor example, I use English US as the language but I will like to use the UK female voice as the guidance. So I edit that lang.ini….[languages]lang = “english US”, “ui\settings\flag_usa.bmp”, “English (US)”, “english_m1_us”I change it tolang = “english US”, “ui\settings\flag_usa.bmp”, “English (US)”, “english_f1_uk”Now I can enjoy the voice more while still using the US english as the language. Even though I don’t know what’s the difference between US and GB English.
do you know what is the largest SD card the unit will accept?.. and does anyone have the new map update?....I just read that the update is by exchange of the original 1g sd card, and sending in the unit along with $100.00 to be exchanged for a 2g SD.....any clues?... thanks RS
