Garmin Nuvi 205 can't unlock maps


First, check to make sure the map file is there. The file name is gmapprom.img. It's located in the Garmin directory. It should be 1GB in size. To do this you need to connect the Nuvi to a PC with a USB cable.

Next, please tell me what year of map you have on your unit, 2009, 2010, etc.

Them, email me your units internal serial number. Its a 10 digit number (not the number on the outside). The number starts with a "3" and can be found by pressing the tools button, then system and then "about".

Please email me at sharcnet-usa AT sharc DOT NET

I TRIED TO UPDATE MY GARMIN 330 STREET WITH THE NEW DISK


TO GET 2009 MAP IS NOT EASY! Software update is, from the Garmin site you can update software easily BUT THE MAP... you must purchase for $69.99 OR if you're a technical person who knows the following instructions you can save some $$$

search torrent for
"CNNANT2009-1 MapID 396"
under torrent sites, you know what you're doing.

Use these instructions if you have downloaded it.

Download these first:
cgpsmapper.exe
gmaptool.exe
MapSetToolKit.exe
and MapSource where u can directly get from Garmin site
http://www8.garmin.com/support/download_details.jsp?id=209

Create these folders on the root drive: (I will choose one to make things easier, you can change)
C:/grmtmp
C:/grmtmp/extract

Connect your GPS to USB, and BACKUP then remove
X:/Garmin/gmapprom.img and gmapprom.sum (may be gmapsupp.[img+sum]) approx. 1GB

1) Copy gmapsupp.img from this torrent to C:/grmtmp;
2) Extract gmaptool.exe, cgpsmapper.exe and mapsettoolkit.exe to C:/grmtmp/extract
3) Open a command prompt, and navigate to the extract folder ("cd/grmtmp/extract")
4) Run "gmaptool -S ../gmapsupp.img" Note that is -(CAPITAL S), lower case s is for different option
5) The above will extract files, you will get some warnings about 10 degrees. Ignore them.
6) Run "cgpsmapper mapset00.mp"
7) Run "MapSetToolKit"
8) In MapSetToolKit, press "Install A Existing Mapset"
8a) TDB File: "mapset00.tdb
8b) Overview map: "mapset00.img"
8c) Registry name: "WhateverYouWant" (I did "Grm2009.1Update")
8d) Leave TYP files blank, and hit "Install"
9) Close MapSetToolKit and run MapSource
10) Ignore any requests to unlock map, not ready yet.
11) Go to "Utilities-Get Unit ID" and Find Device with your GPS plugged in USB. Write down Unit ID.
12) Run Garmin Unlock Utility, Enter that Unit ID at the top.
13) Select under "Select Map Product"
14) Ender 396 for the FID/MapID, use the Generate button to get 25char code.
15) In MapSource go to "Utilities-Manage Map Products"
16) Go to "Unlock Regions" Tab, and hit "Add...", enter 25char code, comment optional
17) Now on the main MapSource screen, type 'm' to enable map tool.
18) You should see a large white rectangle, with rectangle outlines (these represent NA maps)
19) Click and drag to select them all, you can click "Map Set Name" if wanted.
20) Click the "Send to Device" button. Wait an hour. Enjoy.

Garmin 330 GPS using abroad


In order to use the C330 in foreign countries, you need to purchase the maps for those countries and insert the SD card into your unit. You will then have to select the proper maps to use on the unit. These maps are available for purchase at www.garmin.com.

As far as getting around closed roads, your unit will automatically recalculate your route if you are unable to take the suggested route. You can purchase updated maps, but I do not believe this will help you will roads closed for repair.

New Garmin 330 stuck on kansas


Take the unit outside and turn it on. Then select View Maps, at the top of the screen it will say either "Locating satellites" or "Acquiring Satellites". Once the garmin has locked onto the overhead satellites, then it will say "Ready to Navigate".

Locating Satellites take longer than Acquiring Satellites.

Garmin StreetPilot 33o


Did you try to upgrade your Garmin with 2008 maps? If you have the map registration code then you will have to go to garmin's website and get an unlock code. You will need the registration code and also the unit serial number before you can get a new unlock code. The unlock code is base upon your unit serial number and will only work with that unit.

My garmin 330 doesn't show maps


Did this problem occured after trying to install an update?

Try doing a hard reset on the Garmin

First remove the faceplate from the Garmin C330. To accomplish this there is a small indentation under the word Garmin where you can get a finger nail in and pop the faceplate off. On the right side of the unit is a reset button.
